FOREWORD This manual has been prepared for the guidance and safety of all employees of publicly-owned electric utilities. Strict observance of safety rules is necessary to prevent accidents. Lack of enforcement or repeated and flagrant violations of rules can only result in accidents, with accompanying injury and economic loss. In order to facilitate the implementation of the requirements of this manual, a qualified person shall be assigned by the Utility to coordinate the implementation. An accident is defined as an unplanned event invariably preceded by an unsafe act(s) and/or unsafe condition(s) that frequently results in injury or damage and interrupts the completion of an activity. Accidents are an unnecessary waste of both our human and economic resources. Though many accidents are due to unsafe conditions and can be minimized with periodic inspections and preventive maintenance, the majority of accidents are due to unsafe acts and human failure. It is the responsibility of every employee to comply with safety and health standards and all rules that are applicable to their own actions and conduct. In the preparation of this manual, it is recognized that local conditions, laws, and regulations may cause some minor conflicts. In the event of such conflict, you are advised to adhere to the most restrictive regulations governing the situation in question. The publicly-owned electric utility has the responsibility for making interpretations of the rules contained in this manual. This manual shall be observed in all situations to which it applies, without respect to where statements may appear. The American Public Power Association (APPA) has acted as the publisher of this Safety Manual for its member utilities since 1977. The Manual is provided as part of an advisory service of APPA; the use of the Safety Manual by any APPA member is strictly voluntary. Each APPA member and its employees decide the obligations and sanctions that emanate from the use of this Manual. APPA, its Safety Committee Rev. 14, 2007 i

Addendum to the Santee Cooper Safety Manual The Santee Cooper Corporate Safety Committee has chosen not to adopt the following safety rules from the 14th edition of the American Public Power Association’s Safety Manual: Section # Rule # Title 2. 206 Hours of Service Act 4. 401 Personal Protective Equipment (PPE) 5. 503.5 f) Parking -- Only letter ‘f’ of this rule is not adopted. 5. 507.21 a) Metering – Santee Cooper does not require long sleeved shirt for this application due to the protection of rubber gloves. In addition, Rule 113 in Section 1 has been amended to read: 113. Cellular Telephones a) Use of cellular telephones will be limited to the following guidelines: (1) Cellular telephones should be used only for business or high priority personal communication and not for casual use. (2) The volume of the ringer on the cellular telephone must be kept at a minimum as not to startle other workers performing tasks. (3) If a call must be received or made, the worker must ensure that the work area and all personnel in the work area are safe before answering or calling. (4) Cellular telephones will be turned off or placed on voice mail any time you are working with a crew or by yourself where the call would create a safety issue or unnecessary work stoppage.

114 First Aid 114.1 Introduction The material in this section is intended to act as an overall guide to first-aid activities. It is not designed as a self-teaching course, but merely reviews some aspects of first-aid techniques for those who have received training in first aid. The information given is very generalized. Specific action that must be taken at the scene of an emergency cannot be predetermined and will necessarily be modified by the situation. It is important that employees be familiar with the contents of this section and local emergency procedures so as to be better prepared to assist fellow employees in the event of an accident. Employees should follow the current techniques of their employer’s CPR/first aid training provider. Details for first aid may be found in the American Red Cross Textbook on First Aid and the U.S. Bureau of Mines First-Aid Manual. 114.2 General a) Due to potential hazards associated with bloodborne pathogens that cause diseases such as Hepatitis B and AIDS, care shall be taken to limit or eliminate contact with blood or body fluids when administering any type of first aid. Use of rubber gloves, goggles or safety glasses, and a specialized mask for administering CPR is recommended. Employees shall wash hands and other potentially contaminated body areas and remove all contaminated clothing immediately after administering first aid. Employees shall immediately report all exposure to blood and body fluids to their supervisor and follow their Utility exposure control procedures. All blood, body fluids, and used first aid supplies shall be properly cleaned up and disposed of according to federal, state, and local regulations. b) Employees shall be familiar with the basic techniques for first aid so that they may provide emergency treatment to fellow employees. Personnel should be knowledgeable of the treatment for traumatic shock, means of giving artificial respiration, and control of bleeding. Preplanning for a potential emergency situation is most valuable. All 32 Rev. 14, 2007

employees should be aware of the medical services available and how to obtain them. c) Personnel engaged in overhead line work shall know the essential elements of pole top rescue. They should also be familiar with resuscitation techniques and how to apply such techniques in an elevated position. d) Where first-aid kits are supplied, employees shall be familiar with the location, the contents, and the instructions given with the first- aid kit. Each employee shall learn to use this equipment, so they can render treatment when needed. Except for minor injuries, the services of a physician shall be obtained. e) The contents of the first-aid kits shall be inspected to maintain adequate supplies for employee protection. Inspections shall be conducted as frequently as necessary. f) For additional information concerning first-aid requirements, refer to OSHA Standards 29 CFR 1910, Subpart K and 29 CFR 1910.1030. 114.3 Wounds and Control of Bleeding a) A person can bleed to death in a very short time--less than 1 minute. Therefore, in the event of an injury that results in significant bleeding, immediate steps must be taken to prevent the loss of blood. b) Bleeding may be controlled by the following methods: Preferred Method: (1) Direct pressure: Application of pressure directly on the wound. Use of a sterile dressing is preferred. In an emer- gency, use any dressing. Alternate Methods: (2) Indirect pressure on pressure points: Application of pressure on the arterial pressure points in the arm or leg. Pressure points may be combined with direct pressure to restrict severe bleeding (Refer to Figure 1.1). (3) Elevation: Loss of blood can be slowed by raising the wound above the level of the heart. Extreme Method: (4) Tourniquet: The use of a tourniquet is a desperation action. It shall be used only for severe, life-threatening Rev. 14, 2007 33

bleeding that cannot be controlled by any other means. Tourniquets should be applied as close to the wound as possible and should not be loosened except by trained, professional medical personnel, normally at the hospital. (If the tourniquet is loosened, severe shock can result.) 34 Rev. 14, 2007

Figure 1.1 Six Pressure Points to Stop Arterial Bleeding Rev. 14, 2007 35

114.4 Shock a) Shock usually occurs following a severe loss of blood or some type of serious injury. It can occur from a minor injury or even from anxiety or emotional stress. Regardless of the cause, the symptoms are the same and similar treatment is required. b) Shock is easier to prevent than to cure. Every injured person is potentially a shock victim and should be treated as such, whether the symptoms of shock are present or not. c) The following are symptoms of shock: (1) Chalk-like appearance. (2) Dull or anxious expression. (3) Shallow breathing. (4) Weak rapid pulse. (5) Cold, moist skin. d) Recommended treatment for shock includes the following: (1) The victim should be kept warm and comfortable, but not hot. In many cases, the only first-aid measure necessary and possible is to cover the victim underneath as well as on top to prevent loss of body heat. (2) Keep the victim’s body horizontal or, if possible, position him so that his feet are at least 6 inches higher than his head. In any case, always keep the victim’s head low. The single exception to this positioning is the case of a victim who obviously has an injury to his chest and has difficulty breathing. This victim should be kept horizontal with head slightly raised to make his breathing easier. (3) Clear the victim’s mouth of all foreign bodies and make sure he is breathing properly. (4) Loosen tight clothing at the neck, the chest, and the waist. (5) Proper transportation is never more imperative than in the case of a person who may develop shock. It constitutes the most important single measure in the prevention and treatment of shock. Use an ambulance, if possible. If other means must be used, follow the above points as closely as possible. 36 Rev. 14, 2007

114.5 Eye Injuries a) Foreign Bodies: (1) When a small foreign body, such as dust or a wood flake, is on the eye or eyelid, moderate efforts may be made to remove it. The edge of a clean handkerchief or some similar device may be used. Never use a matchstick, knife, or other such instrument that might damage the eye. (2) Objects embedded in the eye must not be removed, except by a physician. Both eyes of the injured employee should be bandaged loosely and the employee taken to the doctor immediately. The injured employee should be told to relax and try not to move his eyes. b) Chemical Burns, Acid or Caustic: Immediate irrigation of the eye with large quantities of clean water is mandatory whenever a chemical substance enters the eye. Flushing of the eye with running water should continue for 15 minutes. c) All eye injury cases, regardless of first-aid measures taken, should be taken to a physician to be checked, and applicable treatment administered. 114.6 Artificial Respiration--General Whenever a person is found unconscious, check to determine if the person is breathing. If the person is not breathing, rescue breathing is to be started as soon as possible without endangering the rescuer. a) In electric shock cases, do not rush in and become a casualty yourself. If possible, de-energize or insulate the power source. Remove victim from electric lines with a dry, nonconductive material. When safe to do so, start rescue breathing. b) Attempt to stop any serious flow of blood. c) Tilt victim’s head back to open airway. Do not waste time trying to clear anything out of victim’s mouth. Commence rescue breathing but if unable to get air into victim’s lungs, stop and clear air passage of obstruction. Reposition the head and try again to breathe into the victim. If still unable to get air into the victim, give six to ten quick manual thrusts upward on abdomen between the rib cage and navel. Then, with a hooking motion with your finger, sweep through the victim’s mouth to remove any obstruction. Retilt the victim’s head Rev. 14, 2007 37

and start again to give rescue breathing. If unsuccessful, repeat the procedure until air passage is open and you can successfully inflate the victim’s lungs. d) If help is available, notify your office or the system dispatcher while one rescuer is giving rescue breathing: BE SURE TO GIVE EXACT LOCATION OF VICTIM. e) Continue uninterrupted rescue breathing until victim is breathing without help or until additional help arrives. f) One breath is given every 5 seconds. If another individual is available to help, changes in rescuers shall be done as smoothly as possible without breaking the rhythm. If necessary to move victim from imminent danger or to prepare him for transport, rescue breathing may be interrupted for not more than 30 seconds. g) Watch victim carefully after he revives. Do not permit the victim to exert himself. h) Treat victim to prevent shock. Transport the victim to a doctor or hospital for examination and disposition. 114.7 Artificial Respiration--Mouth-to-Mouth (Nose) a) Place victim on back. Place head slightly downhill, if possible. Tilt head backward so chin points straight upward. b) Grasp victim’s jaw and raise upward until lower teeth are higher than upper teeth; or place fingers on both sides of jaw near ear lobes and pull upward. Maintain jaw position throughout resuscitation period to prevent tongue from blocking air passage. c) Pinch victim’s nose shut with thumb and forefinger, take a deep breath, and place your mouth over victim’s mouth making airtight contact; or close victim’s mouth, take a deep breath and place your mouth over victim’s nose making airtight contact. If you hesitate at direct contact, place a porous cloth between you and victim. (For an infant, place your mouth over its mouth and nose.) d) Breathe into the victim’s mouth with two long breaths and watch for the victim’s chest to rise. Each breath should last 1 to 1-1/2 seconds. Allow the victim’s chest to deflate between breaths. e) If you do not see the victim’s chest rise and fall, reposition the head and try again. If repositioning the head is not effective, administer six to ten manual abdominal thrusts and sweep the mouth 38 Rev. 14, 2007

for any foreign objects. Repeat this step until the victim’s airway is opened. f) If the victim’s chest does rise and fall, take the victim’s pulse at the carotid artery. Maintain the airway by continuing the downward pressure of your hand on the forehead. Use the hand that is holding the victim’s chin up to feel for the pulse. Slide your fingers down from the chin and find the Adam’s apple with your fingertips, about halfway between the victim’s chin and collarbone. Draw your fingers back toward you into the groove beside the Adam’s apple. Press lightly to feel the pulse with the most sensitive part of your fingertips. Remember not to use your thumb because it has its own pulse. Feel very carefully to find a pulse; take at least 5 seconds and up to 10 seconds if necessary. If there is no pulse, begin external cardiac compression as described in Paragraph 114.8. g) If the victim has a pulse, continue rescue breathing at a rate of once every 5 seconds, or 12 times per minute. Lift your mouth away after each inflation, turn your head, and watch the victim’s chest fall as you allow time for the lungs to empty after each breath. h) Check the pulse once a minute (after every 12 breaths) to be sure that the heart is still circulating blood even though breathing has stopped. Continue to breathe for the victim as long as the breathing inadequacy continues or until additional help arrives. 114.8 Cardiopulmonary Resuscitation (CPR) The information given in this section is not intended as instruction for the administration of cardiopulmonary resuscitation. Such treatment should be given only by persons who are properly trained and qualified. The following is a reminder to those persons of the points to be followed. If not administered properly, CPR may result in other serious injuries. Perform CPR only when indicated. If no pulse can be felt, CPR may be started. CPR is always accompanied by rescue breathing. If available, two persons should perform rescue efforts for the victim; one should give rescue breathing while the other performs external heart compression. Five compressions should be given for every one ventilation. If only one Rev. 14, 2007 39

rescuer is present, 30 compressions should be given for every two full breaths. a) Place victim on back on a firm surface. b) Put hands on breastbone. Place heel of one hand on lower one-half of breastbone with other hand on top of first. c) Press downward. Apply pressure until breastbone moves 1-1/2 to 2 inches. d) Lift hands and permit chest to return to normal. e) Repeat compression 80 to 100 times per minute. f) After the first four cycles of compressions and ventilations for one-person CPR and after 10 cycles for two-person CPR, stop and check for a spontaneous pulse. After that, pause every few mintues to check for spontaneous pulse. CAUTION: Never begin chest compressions on someone whose heart is still beating, even if the victim’s pulse is weak or irregular. Performing compressions on a person whose heart is functioning could cause the heart to stop. 40 Rev. 14, 2007

115 Training 115.1 Employee Training a) Employees shall be trained in and familiar with the safety- related work practices, safety procedures, and other safety requirements in this section that pertain to their respective job assignments. b) Employees shall also be trained in and familiar with any other safety practices, including applicable emergency procedures that are not specifically addressed in this section but are related to their work and necessary for their safety. c) Employee training is not confined to this section and can be found throughout this Safety Manual in more specific sections. 115.2 Qualified Employee Training a) Qualified employees shall be trained and competent in the skills and techniques necessary to distinguish exposed live parts from other parts of electrical equipment. b) Qualified employees shall be trained and competent in the skills and techniques necessary to determine the nominal voltage of exposed live parts. c) Qualified employees shall be trained and competent in the skills and techniques necessary to determine the minimum approach distances corresponding to the voltages to which they are exposed. d) Qualified employees shall be trained and competent in the proper use of the special precautionary techniques, personal protective equipment, insulating and shielding materials, and insulated tools for working on or near exposed energized parts of electrical equipment. e) Training may be classroom or on-the-job. f) Training shall establish employee proficiency in the work practices required. 115.3 Safety Compliance Regular supervision and inspections, conducted on at least an annual basis, will determine that each employee is complying with the safety- related work practices required. Rev. 14, 2007 41

115.4 Additional Training and Retraining An employee shall receive additional training (or retraining) under any of the following conditions: a) If supervision and annual inspection indicate that the employee is not complying with safety-related work practices. b) If new technology, new procedures, or changes in procedures cause new safety-related work practices to be introduced. c) If the employee must use safety-related work practices that they do not normally use (used less than once a year). 42 Rev. 14, 2007

115.5 Job Briefings a) The employee in charge shall conduct a job briefing with the employees involved before the start of each job. The job briefing will at least cover the following subjects: hazards associated with the job, work procedures involved, special precautions, energy source controls, and personal protective equipment requirements. b) If the work or operations to be performed during the work day are repetitive and similar, at least one job briefing shall be conducted before the start of the first job of each day or shift. Additional job briefings shall be held if significant changes, which might affect the safety of the employees, occur during the course of the work. c) A brief discussion is satisfactory if the work involved is routine and if the employee, by virtue of training and experience, can reasonably be expected to recognize and avoid the hazards involved in the job. A more extensive discussion shall be conducted if the work is complicated or extremely hazardous, or the employee cannot be expected to recognize and avoid the hazards involved in the job. d) An employee working alone need not conduct a job briefing. However, the employee shall ensure that the tasks to be performed are planned as if a briefing were required. 115.6 Pole-Top Rescue Electric contacts may occur at elevated locations. When such a contact does happen, immediate rescue is necessary. Rescue operations will vary, depending upon the prevailing situation. The information in this section is intended to serve only as a guide. Preplanning and training for a possible emergency is important. a) Size up the situation. The rescue effort will be far more effective if a few seconds are devoted to full identification of the situation. b) Radio for help. Prepare the equipment you will need. c) Protect yourself. Apply necessary protective equipment. Use necessary personal protective devices. Then clear the victim from the hazards. d) Position yourself for rescue. Rev. 14, 2007 43

e) Proceed with rescue or resuscitation as dictated by the conditons: (1) If victim is conscious: (a) Reassure the injured. (b) Be watchful for shock. (c) Help injured descend the pole. (d) Administer first aid. (2) If victim is unconscious and breathing: (a) Watch breathing closely. (b) Lower injured to ground. (c) Give first aid. (d) Summon medical assistance. (3) If victim is unconscious and not breathing: (a) Give victim two full breaths. (b) Lower the victim to the ground as soon as possible and initiate CPR. Note: If it becomes apparent that the victim cannot be lowered to the ground in a short period of time, it may become necessary to apply pole-top resuscitation. f) Pole-top resuscitation: (1) Mouth-to-mouth artificial respiration should normally be used. The method is similar to that described above, except for the position of the victim. g) Lowering victim from the pole: (1) For field expediency, the following method is presented: (a) Place handline on crossarm, preferably 2 or 3 feet from pole. (b) Make one wrap of line. Do not cross line over fall line. (c) Pass handline under armpits. (d) Tie three half-hitches. (e) Cinch line tightly around victim. (f) Remove slack in line. (g) Cut victim’s safety. (h) Lower victim. 44 Rev. 14, 2007

(2) Depending upon the situation, alternate hitching or lowering methods might be more desirable. 115.7 After Rescue All victims of electric contact shall be transported to a doctor or a hospital for examination and observation. 115.8 Training in Resuscitation and Rescue All employees engaged in electrical work shall receive training in resuscitation and in rescue from their working environment (poles, structures, manholes, boilers, aerial baskets, confined or enclosed spaces, etc.). Rev. 14, 2007 45

Section 2 HEALTH AND ENVIRONMENTAL CONTROL This section deals with general health areas and depicts some of the control methods that employees must use for their protection. The general principles outlined in this section are applicable to all work activities. However, specific control measures applicable to a specific work activity are covered in the section dealing with that work activity. Work processes and work locations can present health hazards to the employee. Because most of these health hazards do not pose an immediate danger, they are frequently not given the attention that is necessary. In order for employees to be fully protected, they must become as knowledgeable as possible of potential health hazards. Thorough understanding of the principles of this section is essential. 201 Confined or Enclosed Spaces A confined space is large enough for an employee to enter and perform assigned work and has limited or restricted means for entry or exit and is not designed for continuous employee occupancy. A permit-required confined space has one or more of the following characteristics: (1) contains or has a potential to contain a hazardous atmosphere(s); (2) contains a material that has the potential for engulfing an entrant; (3) has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross section; or (4) contains any other recognized serious safety or health hazard. Determine if the space to be entered is a permit-required confined space and enter accordingly. a) Only employees who have been properly trained on the hazards associated with confined or enclosed space work shall be allowed to enter a confined space or enclosed space. 46 Rev. 14, 2007

b) Employees who enter enclosed spaces or who serve as attendants shall be trained in the hazards of enclosed space entry, enclosed space entry procedures, and enclosed space rescue procedures. c) Before any entrance cover to a confined or enclosed space is removed, it shall be determined that there are no temperature or pressure differences, or other hazardous conditions that may injure the employees removing the cover. d) When covers are removed from confined or enclosed spaces, the opening shall be guarded by a railing, temporary cover, or other temporary barrier. e) Before entering a confined or enclosed space, all levels of the space shall be tested for lack of oxygen and then for the presence of flammable or toxic gases and vapors. Monitoring instrumentation must be calibrated. f) If a hazard increasing work activity is to take place in a confined or enclosed space (i.e., welding, painting, working with solvents and coating), the air in the space shall be continuously tested for the presence of flammable or toxic gases and vapors or insufficient oxygen. Forced ventilation shall be used as required. g) If flammable or toxic gases or vapors are detected or if an oxygen deficiency is found, the space shall be continuously tested and forced ventilation shall be used to maintain oxygen at a safe level and to prevent a hazardous concentration of flammable or toxic gases and vapors. h) While work is being performed in an enclosed space, a person with CPR and basic first aid training shall be immediately available to render emergency assistance if there is reason to believe that a hazard may exist in the space or if a hazard exists because of traffic patterns in the area of the opening used for entry. If work is to be performed in a confined space, the Utility’s written permit system shall be followed. A properly trained attendant shall be stationed outside the confined space. The attendant shall maintain continuous communication with the employees authorized to be in the confined space. The attendant shall be able to recognize confined space hazards and changing conditions in the confined space that could affect employees in the space. In the event of an emergency, the attendant shall not enter the Rev. 14, 2007 47

confined space, but shall be able to summon emergency and rescue services. i) Entry into a confined or enclosed space with an unsafe atmosphere shall be avoided if at all possible. Employees required to enter a confined or enclosed space with an unsafe atmosphere shall be equipped with a fresh-air breathing apparatus, body harness, and lifeline monitored by a properly trained attendant. Necessary rescue personnel and equipment shall be available in the event of an emergency. j) Electric welding, gas welding, cutting, or any other hot work shall not be performed on the interior, exterior, or near the openings of any confined or enclosed space that may contain flammable or explosive gases or vapors until the space has been properly cleared. k) Compressed gas bottles shall not be taken into a confined space. l) Safe access to the confined space shall be maintained at all times. If possible, all cords, hoses, leads, etc., shall be routed through an entrance other than the employee access into the confined space. m) Before employees are allowed to enter a confined space, all electrical and mechanical energy sources that could affect the employees working in the space shall be physically rendered inoperative, locked out, and tagged. If required, the space shall be drained, vented, and cleaned. n) For additional information concerning confined space requirements, refer to OSHA Standards 29 CFR 1910.269 and 29 CFR 1910.146. 202 Hazardous Energy Control/Lockout-Tagout (Refer to Utility Dispatching Policies) a) Before starting work on any circuit, machine, belting, shafting, or other apparatus that is out-of-service, employees shall assure themselves that the apparatus is physically rendered inoperative and that a standard Hold Card, tag, and/or lockout device is properly attached to the apparatus control. b) No switch, governor, valve, throttle, or other device used to put a circuit or equipment into service shall be operated while a Hold Card or similar device is attached to it. 48 Rev. 14, 2007

c) A Hold Card, or similar device, that has been placed for the protection of workers shall be removed only by authorization of the person in whose name it was placed, and then only after the work has been completed and workers and tools are in the clear. (Follow Utility operating instructions pertaining to the equipment involved.) d) Each employee in charge of work on any equipment shall have their Hold Card or similar device secured to the apparatus control. Note: See Paragraphs 510.1, 510.2, 510.3, 510.4, and 510.15 covering Generating Stations. e) For additional information concerning Hold Cards and tag requirements, refer to OSHA Standards 29 CFR 1910.269 and 29 CFR 1910.147. 202.1 Control of Hazardous Energy/Lockout-Tagout Includes employees authorized to work on Utility System. a) Safety (1) Safety must be the first consideration. All safety rules of the company plus the APPA Safety Manual must be known and followed by each employee. Employees are expected to use judgment, common sense, and diligence in following these rules. Visually inspect all equipment for damage and identify possible problems before starting work or switching. Lines, cables, stations, or equipment are considered de-energized and ready for work only after the equipment has been identified and isolated, a clearance has been issued, and the equipment has been tested and grounded. b) Authority (1) Authority of the system operator: the system operator has the authority and responsibility for switching and clearances on lines, cables, stations, and equipment of 600V or above. (2) The system operator has the authority and responsibility for switching and clearances on lines 35 kV and lower voltage. System operator shall follow operating guidelines for switching and clearance of lines above 35 kV. “System operator” refers to the employee with jurisdictional authority. Rev. 14, 2007 49

(3) System operator may authorize employees to act in the capacity of the system operator for switching and clearances in sections of the system. (4) System operator issues orders to open and close switches (including underground elbows), to place and remove tags, and to de-energize or clear lines, cables, stations, and equipment on which employees will work, except where standing orders or regulations have been given covering such operations. c) Interconnections with Other Utilities (1) The designated representative has jurisdiction over interconnections with other utilities and systems. They shall arrange with other utilities for switching and clearances on all interconnections, and will inform the system operator affected system operation center of the duration and reason for the clearances. (2) Where lines of other utilities are involved in the operation of the system, system operators shall cooperate with those of other utilities who have jurisdiction, giving and accepting switching orders through them switching connecting lines or stations. d) Interconnections with Customer Primary Systems (1) Where the customer primary system is mapped and identified, the system operator may issue orders for switching and clearances on the customer lines, cables, stations, and equipment. (2) Where the customer primary system is not identified, the system operator shall not issue orders for switching and clearances. Employees must ensure the lines, cables, stations, and equipment are de-energized, then identified, isolated, tagged, tested and grounded before work begins. Customers may also have lockout and tag-out procedures that must be observed. e) Communications (1) Communications in connection with switching and clearances shall be given by system operator directly to the employee in charge of operating the switch or receiving the 50 Rev. 14, 2007

clearance. Communications may be relayed through a third party if all parties are in agreement. (2) Switching orders on clearances shall be repeated word for word back to the speaker, using correct designation of lines, cables, or equipment. Speakers shall identify themselves by name each time. f) Safety Tags (1) DANGER DO NOT OPERATE tags are red. These tags must be filled out and attached to the control device or card holder of each switch or breaker that could energize the line, cable, station, or equipment to be worked on. (2) Equipment tagging uses the DANGER DO NOT OPERATE tag in substations, switching stations, distribution equipment, and in special situations. When the DANGER DO NOT OPERATE tag is placed on the switch and control devices normally used to energize the line, station, or equipment to be worked on. (3) Attach the appropriate safety tags to equipment during switching and clearance operations. (4) Attach tags to the control devices of circuit breakers and switches. (5) Place tags in holders provided on or near the operating mechanisms of switch operating mechanisms. (6) Attach tags to switch-operated single-pole disconnect switches in substations and other appropriate locations. (7) Attach tags to cable or fuse handle of underground cable. (8) Tags will be substantial enough to withstand adverse environmental conditions. Tags will have an attachment point with a breaking strength of at least 50lbs. Tags may not be reused. g) Tagging Procedures (1) Follow these steps to use a DANGER DO NOT OPERATE tag when obtaining clearance from the system operator. • Name of employee in direct charge of the work who is requiring the clearance. Rev. 14, 2007 51

• Name of the system operator who is issuing the switching orders. • Time and date that the switch is opened and closed. • Signature of the employee operating the switch. • System operator incident number. (2) Complete a DANGER DO NOT OPERATE tag for each switch to be opened or verified OPEN for the purpose of issuing a clearance. h) You must request a HOLD tag before performing hotline work on lines 35 kV and higher. i) You may request a HOLD tag before performing hotline work on primary circuits of 35 kV and lower. This process describes how to use a HOLD tag: (1) Employee – Requests a HOLD tag before beginning hotline work on lines of 55 kV or higher. (2) Orders the breaker placed on non-reclose, and a HOLD tag attached to the circuit breaker or recloser’s control device. (3) Employee – Attaches the HOLD tag. (4) System operator – Notifies the employee that the recloser is on non-reclose and is HOLD tagged. (5) Employee – Contacts the power dispatcher or system operator if a line relays out while under a HOLD tag. (6) Power dispatcher or system operator – Confirms with employee that the crew is in the clear before re-energizing the line. j) Self-Protection Clearance (1) Requirements: Employees familiar with lines, cables, stations, or equipment may use optional self-protection clearances. Employees also must be familiar with Personal Protective Equipment (PPE) rules. (2) Self-protection clearances may be used only on single- phase and three-phase radial distribution lines where other points of electrical contact or sources of hazardous induced voltage from adjacent energized lines do not exist. (3) No more than one self-protection clearance may be taken on the same line at any one time. 52 Rev. 14, 2007

(4) Requirements: The DANGER DO NOT OPERATE tag becomes the legal record of the clearance and must be completed and returned to the service center with the switching, clearance and customer outage information by the employee who obtained the clearance. These self protection tags must be retained by the service center for a minimum of three years. (5) Follow these steps to obtain and release a self protection clearance. • Fill out a DANGER DO NOT OPERATE tag: • Check the “self-protection” box • Name of employee taking the clearance • Bounds of clearance • Exact location • Switch number • Time (6) Take a self-protection clearance by opening and tagging the section of line with the DANGER DO NOT OPERATE tag. Visually inspect the line to ensure there are no other points of electrical contact (normal opens, etc.) (7) Confirm that the line is identified, isolated, tested, and grounded. (8) Proceed with and complete the job. (9) Release self-protection clearance by removing personal protective grounds and ensuring all workers and equipment are in the clear. 10) In normal operating conditions (non-storm), verify with the system operator that the hotline work switch is in the OFF position before energizing the line, cable, or device. k) Clearance for Interconnections with Other Utilities (1) The Utility shall arrange with other utilities 48 hours in advance for switching and clearances on all interconnections, and will inform the affected system operations center of the duration and reason for clearances on interconnections. (2) Follow these steps to obtain and release a clearance for non-company employees. Rev. 14, 2007 53

• System operator: Issues two clearances to the Utility employee: one for the Utility employee and one for the non-Utility employee. • Employee: Ensures the non-Utility employee understands the full extent of the clearance, and what lines, cables, stations, or equipment are isolated and tagged. • Issues the non-Utility employee their clearance to proceed with the work. The Utility employee may then leave the jobsite. • Non-Utility employee: Proceeds with and completes the job. • Releases the clearance to the same Utility employee. • Utility employee: Inspects the lines, cables, stations, and equipment. • Ensures the non-utility employee is clear and understands the system is to be re-energized. • Releases the clearance to the system operator. • System operator: Orders both sets of tags removed and the system restored to normal. 202.2 Distribution Switching Procedures The following procedures describe basic switching orders for the underground and overhead systems. The procedures and radio communications can be modified to fit particular circumstances. Complete and detailed coverage of all possible situations have not been attempted. Radio communications appear in italics. a) Distribution Hotline Work – Non-Reclose without Hotline Work Switch: 1) At (substation name) place Circuit Breaker (CB) ## on NON-RECLOSE and HOLD tag for (name). 2) To restore: At (substation name) remove (name) HOLD tag and restore the reclosing on CB ## (2) Distribution Hotline Work – Non-Reclose with Hotline Work Switch: 54 Rev. 14, 2007

• At (substation name) place CB ## on NON- RECLOSE and HOLD tag for (name), and turn hotline work switch ON. • To restore at (substation’s name) remove (name) HOLD tag, restore the reclosing on CB ## and turn hotline work switch NORMAL. (3) Distribution Ground Overcurrent Relay and Cutout Switch: While switching in a distribution substation, ground trips should be cut only where an abnormal condition exists, where single-phase switching could trip the CB. • As (substation name) cut out the ground trips to CB ##. • To restore: At (substation name) cut in the ground trips to CB ##. (4) Distribution CB Switching To clear a Station CB Using Auxiliary Bus: Follow these steps when paralleling two CBs on the auxiliary bus that are fed from separate transformers in a two-bank station. • Match the Load Tap Changing (LTC) • Place the controls in the OFF position. • Turn the reclosing OFF and hotline switch ON in each CB. • At (substation name) place CBs ## and ## on NON-RECLOSE, and hotline work switch ON. Close the auxiliary bus disconnects on CBs ## and ##. Open CB ## (the one to be cleared). Check that the contact position indicator shows OPEN. Open its line and main bus disconnects and tag for (name). Restore the reclosing line on CB ##, and turn hotline switch OFF. • To Restore: At (substation name) remove (name) tags. Check that CB ## is mechanically open and on NON-Reclose and hotline work switch is ON. Cut out reclosing on CB ##. Close line and main bus disconnects and close CB ##. Check for load. Open auxiliary bus disconnects on CBs ## Rev. 14, 2007 55

and ##. Restore non-reclosing. Turn hotline work switch OFF in CBs ## and ##. (5) To clear a Station CB Using an Alternate Substation’s Circuit: Follow these steps to clear a station CB using an alternate substation’s circuit. • Before transferring the load, place the CB to which the load is being transferred to NON- RECLOSE. • Place both circuits in NON-RECLOSE so that in the event of a fault on the tie switch, neither breaker would close back in. • Place the LTC at one station (preferably the one whose CB is to be cleared) in the OFF position so the two LTCs do not interact with each other. • At (substation name where the CB is being cleared) place the CB ## on NON-RECLOSE. Turn the LTC control OFF (have switch operator close field switch). • At (substation name) open CB ## (to be cleared), check that the contact position indicator shows OPEN. Open its line and main bus disconnects and tag for (name). Restore the LTC controls to AUTO. • After load transfer is complete, restore the reclosing on the CB to which the load had been transferred. • To restore: Before transferring the load, place the CB that is carrying the load on NON-RECLOSE. • At (substation name where CB is out of service) remove (name) tag. Check that CB ## is mechanically open and on NON-RECLOSE. Turn the LTC controls OFF. Close line and main bus disconnects, and close CB ##. Check for load. (Have switch operator open tie switch in the field). Restore reclosing to CB ##, and restore the LTC controls to AUTO. 56 Rev. 14, 2007

• After load transfer is complete, restore the reclosing on the CB that was carrying the load. 202.3 Distribution Substation Load Tap Changing (LTC) Whenever all load is being transferred from a distribution substation follow these steps. • At (substation name) place the LTC on NEUTAL and OFF. Open the bank low side switch and tag for (name). Open the bank high side switch ####, and tag for (name). • To restore: At (substation name) check that the LTC is on NEUTRAL and OFF. Remove all (name) tags. Close the bank low side switch. Switch to restore load to station, (monitor and adjust LTC voltage level as load increases). Return LTC controls to AUTOMATIC. 202.4 Substation Transformer High Side Protection (1) Follow these steps to clear a station with a high side switch. • Transfer the load. • At (substation name) place LTC on NEUTRAL and OFF.

When choosing fall arrest equipment or positioning devices, consideration should be given to the type of work to be performed and limiting the shock load on the body of the wearer in the event of a free fall. Employees working from aerial lifts shall wear full body harnesses with a shock-absorbing lanyard, attached to the appropriate anchor point on the aerial lift. b) All fall protection equipment shall be inspected prior to use by the wearer as required by the manufacturer and applicable ANSI standard. Rev. 14, 2007 61

c) Employees shall rig fall arrest equipment so that they cannot free fall more than 6 feet or contact any lower object. When positioning devices are used, they shall be rigged to limit free fall to 2 feet. Anchorage points for fall arrest equipment and positioning devices shall be capable of supporting a shock load and located above the employee’s body belt or harness attachment point. d) Body belts shall be worn snug just above the wearer’s hips. e) Employees shall avoid the following lanyard snaphook connections to help eliminate the possibility of accidental disengagement (roll-out): (1) Snaphooks without locks. (2) Two (or more) snaphooks connected to one D-ring. (3) Two snaphooks connected to each other. (4) A snaphook connected back on its integral lanyard. (5) Improper dimensions of the D-ring, rebar, or other connection to the snaphook dimension. f) Snaphooks may not be connected to loops made in webbing type lanyards. g) When vertical lifelines are used, each employee shall be protected by a separate lifeline. The lifeline shall be properly weighted at the bottom and terminated to preclude a device such as a rope grab from falling off the line. h) Horizontal lifelines should be limited to two persons at one time between supports. i) Fall arrest equipment shall be used on poles by qualified employees when such conditions as ice, high winds, design of structure (such as no hand holds) or the presence of contaminants exist that could cause the employee to lose his grip or footing. Exclusion: Fall arrest equipment is not required for qualified climbers who are climbing or changing positions on poles, towers, or similar structures unless conditions such as those listed above exist. This exclusion does not apply to un-qualified climbers undergoing on-the- job training, even though they may be considered qualified employees for other purposes. 62 Rev. 14, 2007

204 Lighting Where natural illumination is not sufficient, artificial lighting shall be used. Temporary lighting (excepting battery powered) shall be protected with approved guards. In areas where flammable or combustible vapors, liquids, gases, dust, or fibers may be present, only intrinsically safe equipment approved for the hazardous location shall be used. 205 Exhaust Ventilation a) Exhaust systems, when provided at the work location, shall be used. b) When an exhaust system does not provide adequate protection, other protective means, such as an approved respirator, shall be used in addition to (or in lieu of) the exhaust system. c) For additional information concerning ventilation requirements, refer to OSHA Standard 29 CFR 1910.94. 206 Hours of Service a) No employee should work more than a total of 16 hours time on duty, immediately preceded by 8 or more consecutive hours off duty time. b) Duty begins when the employee reports to work and ends when the worker is released from work, and includes breaks, interim periods, or time spent engaged in any service for the employer. 207 Fire Protection 207.1 Fire Protection and Emergency Plans a) Employees shall become familiar with and follow all Utility emergency procedures and plans. b) Employees shall familiarize themselves with the emergency exits, alarm signals, and escape procedures when working inside a building or structure.

Fire exits or doors shall not be locked, chained, or barricaded at any time. d) Employees shall be familiar with both the location and the operation of all fire protection equipment in the vicinity of their work area. e) Fire protection equipment shall be properly located at all times. Except for actual use, employees shall not move or remove such equipment without proper authority. f) Only properly trained employees equipped with the necessary protective equipment shall attempt to extinguish or contain a fire. g) Fire brigade members shall follow the Utility’s established policies and procedures. h) For additional information concerning fire protection and emergency plans, refer to OSHA Standards 29 CFR 1910.38 and 29 CFR 1910.156. 64 Rev. 14, 2007

207.2 Fire Extinguishers a) All employees shall know the classes of fire, their burning characteristics, and the proper extinguishing agent to be used: (1) Class “A” fires involve ordinary combustibles, such as wood, paper, some plastics, and textiles. Extinguishing agents include water, multipurpose dry chemical, high- expansion foams, and Halon. (2) Class “B” fires involve flammable liquid and gas fires, such as oil, gasoline, paint, and grease. Extinguishing agents include carbon dioxide, dry chemical, low-expansion foam, and Halon. (3) Class “C” fires involve energized electrical equipment. Extinguishing agents include carbon dioxide, dry chemical, and Halon. (4) Class “D” fires involve combustible metals, such as magnesium, potassium, zinc, and titanium. Extinguishing agents include dry powder. b) Halon is a gaseous extinguishing agent suitable for combating both Class “B” and “C” fires, especially at indoor locations. Both agents are slightly toxic in low concentrations (less than 5 percent) and will cause unconsciousness in a short period of time when the concentration is above 15 percent. When the extinguishing agent is released, precautionary measures similar to those for toxic confined spaces should be used. c) Employees shall not enter confined spaces after using carbon dioxide extinguishers until the area has been thoroughly ventilated. d) Fire extinguishers must not be blocked or hidden behind material or machines. e) All fire extinguishers shall be conspicuously marked and shall be located close to the fire hazard, but not so close that they would be damaged or cut off by the fire. f) Extinguishers that contain carbon tetrachloride or chlorobromomethane shall not be used. g) Inverted type extinguishers such as self-generating soda acid or self-generating foam or gas cartridge water shall not be used. Rev. 14, 2007 65

h) All employees shall be trained on the operation of the fire extinguishers in their work area. The following general guidelines shall be considered when using a portable fire extinguisher: (1) Look to see what is burning and be sure to use the correct extinguisher. (2) Approach the fire from upwind if possible. Try to get approximately 6 to 8 feet close to the fire (depending on the size and type of the fire). (3) Hold the extinguisher upright and aim it at the base of the fire. (4) Be efficient. Most fire extinguishers are emptied in a few seconds. i) Fire extinguishers shall be inspected visually at least once a month and thoroughly inspected at least annually. j) For additional information concerning the requirements for fire extinguishers, refer to OSHA Standard 29 CFR 1910.157. 207.3 Hydrants, Standpipes, and Hose Stations a) Vegetation, snow, and stored equipment shall be kept away from hydrants, hydrant houses, and valve and hose stations. b) Control valves shall be tested frequently and shall be maintained in the proper position. c) Connections should be checked with the local fire department to be sure that they are of a size and thread that will fit their equipment. d) Only lined hose shall be used for hose stations. e) Fire hose station hose and nozzles shall not be used for any other purpose. f) When water flows through a fire hose and nozzle, the reverse action of the nozzle, called “nozzle reaction,” can be considerable, tiring a person in a short period of time. A minimum of two persons should be available to eliminate this effect. g) All movements involving an operating hose line shall be accomplished with slow deliberate movements. h) The hose line should be kept in line with the direction of the nozzle stream flow. A sharp bend directly behind the nozzle will cause severe pressure to turn the nozzle and create excessive work and potential danger to the user. 66 Rev. 14, 2007

i) After use, all hose shall be thoroughly dried and properly racked in the hose station. j) For additional information concerning hydrants, standpipes, and hose stations, refer to OSHA Standard 29 CFR 1910.158. 207.4 Sprinkler Systems a) Sprinkler system valve stations shall be kept free of all obstructions. b) Valves for sprinkler systems shall be maintained in the proper position. c) A minimum clearance of 36 inches shall be kept between the top of material storage and a sprinkler head deflector. d) For additional information concerning sprinkler systems, refer to OSHA Standard 29 CFR 1910.159. 208 Security 208.1 General a) Any individual or group with the intent to attack employees and damage/destroy your plant in order to achieve economic and psychological effects and which also possesses the capability (organizational structure, motivated and trained personnel, weapons, explosives, intelligence and logistical support) is a threat to your plant and personnel. b) The threat’s capabilities, target the plant’s overall physical security traits, the physical environment (geography, urban, rural, transportation infrastructure, etc.), how susceptible you the plant is to surveillance, weather and other tangible and intangible items add up to just how vulnerable the plant really is. In terms of tangible traits, the perceived value of the plant as target and the amount of economic and psychological damage that its destruction could bring to a community, region, state or even a nation. The attitudes of plant personnel regarding security awareness and their willingness to maintain a proactive approach toward security are also an intangible, but vital, part of your facility’s overall vulnerability. c) In order to determine the level of threat that may be imposed on the plant, consider the following: Rev. 14, 2007 67

• How critical is the plant, in terms of target value? Would severe damage or total loss impact significantly on local, regional, or national economies, politics, government operations and civil society? • How accessible is the plant, physically to surveillance? Is it easy to bring vehicles into and out of the facility? How effective is the access control program? How vulnerable are our IT systems to hacking and penetration? Are handheld and vehicular radios routinely used, and, if so, can the transmissions be encrypted? • How long would it take to recupe and return to full operational status following a disaster or attack? How long to repair or by-pass (if possible) critical mechanical or control systems within the plant? What components would take the longest to repair or replace and are, therefore, most critical? • How vulnerable is the plant to an attack that could achieve a significant level of damage? • If an attack is successful, what is the potential effect? Political, economic, psychological, symbolic, or all of the above? • How easy is it to recognize the plant and critical nodes/components within the facility? Signs that identify critical components/offices and a website “gives away” critical information. d) For further information on cyber or physical security refer to the North American Electric Reliability Corporation Security Guidelines. See the NERC website for more information at www.nerc.com. 208.2 Personal a) Although the technical portions of vulnerability identification and mitigation recommendations fall to the plant’s Security Director/Manager and/or a contract security consultant, there is much that can be done by everyday plant employees and plant management. It starts with the simple principle of awareness of ones’ surroundings. Awareness of what goes on inside and in the immediate area within a 68 Rev. 14, 2007

distance of about 200 meters from the plant, in all directions should be maintained at all times. Making a general note of conditions of fencing and gates, security lighting, surveillance systems and alarm systems is a great way to make strides toward identifying vulnerabilities. b) Include in this effectiveness of security procedures, a lock and key control program, professional security guard services, a layered system of access control measures, and pre-hire background investigations. c) Never lose sight of the fact that protection of people takes precedence over protection of things. Employees are the greatest assets within any business and their safety and welfare always comes first. In most cases, positive access control to the facility is the single most critical element, along with well-trained security officers, and a proactive background investigation policy for new hires and contractors. 208.3 Generating Facilities a) Determine how susceptible to surveillance your plant is. Look for vulnerabilities in procedures or barrier systems. Remember that in order to assess vulnerabilities effectively, one must fully understand the nature of any threat against your plant, whether terrorist or criminal. b) Assessing vulnerabilities has to be done in concert with local, state and federal law enforcement, other private or public utilities in your area, industrial facilities and any professional associations in an aggressive program of information and intelligence sharing. Federal Emergency Management Agency (FEMA), local fire and emergency service providers, regional and local Red Cross, hospitals and others can complete the picture as to overall vulnerability to attacks and the potential impact on your personnel and the community as a whole. 208.4 Emergency a) In the event of a terrorist attack on your plant, your goal is to respond, mitigate and restore. Also, nothing you do regarding security can be guaranteed to prevent an attack. Rev. 14, 2007 69

Section 3 CHEMICAL AND PHYSICAL HAZARD CONTROL 301 Material Handling and Storage a) An employee shall obtain assistance in lifting heavy objects or use power equipment. b) When two or more persons carry a heavy object that is to be lowered or dropped, there shall be a prearranged signal for releasing the load. c) When two or more persons are carrying an object, each employee, if possible, should face the direction in which the object is being carried. Employees shall not attempt to lift beyond their capacity. Caution shall be taken when lifting or pulling in an awkward position. The right way to lift is easiest and safest. Crouch or squat with the feet close to the object to be lifted; secure good footing; take a firm grip; bend the knees; keep the back vertical; and lift by bending at the knees and using the leg and thigh muscles. d) Employees should avoid twisting or excessive bending when lifting or setting down loads. e) When moving a load horizontally, employees should push the load rather than pull it. f) When performing a task that requires repetitive lifting, the load should be positioned to limit bending and twisting. The use of lift tables, pallets, and mechanical devices should be considered. g) When gripping, grasping, or lifting an object such as a pipe or board, the whole hand and all the fingers should be used. Gripping, grasping, and lifting with just the thumb and index finger should be avoided. h) In areas not restricted to qualified employees only, materials and equipment may not be stored closer to energized lines or exposed energized parts of equipment than the following distances plus the maximum sag and side swing of all conductors and providing for the height and movement of material handling equipment: (1) For lines and equipment energized at 50 kV or less, the distance is 10 feet. 70 Rev. 14, 2007

(2) For lines and equipment energized at more than 50 kV, the distance is 10 feet plus 4 inches for every 10 kV over 50 kV. i) Materials stored near energized lines or equipment must meet the spacing requirements of OSHA Standard 29 CFR 1910.269 (k) and 1910.176. 302 Explosives a) The transportation, handling, storage, and use of dynamite and other explosives, including blasting agents, shall be directed and supervised by persons of proven experience and competency in blasting and use of explosives. b) A blaster shall be qualified, by reason of training, knowledge, or experience, in the field of transporting, storing, handling, and use of explosives, and have a working knowledge of state and local laws and regulations which pertain to explosives. Blasters shall be required to furnish satisfactory evidence of competency in handling explosives and performing, in a safe manner, the type of blasting that will be required. In addition, blasters shall be able to give and understand written and verbal orders; shall be in good physical condition; and not addicted to, or under the influence of, intoxicants, narcotics, and similar drugs. (Similar drugs may include certain prescription drugs if such drugs diminish the physical ability or mental capacity of the blaster.) c) Notification shall be made before any explosives or blasting agents are brought on the jobsite. Such notification should accompany a comprehensive detailed blasting program. The required program must, as a minimum, show proposed methods and procedures for conforming with these and referenced standards and regulations, including the following: • Method and equipment for transporting explosives and detonators. • Type and location of storage facilities. • Type and quantity of explosives and detonators. • Primer assembly procedure and location. • Employee training programs. • Provisions for protecting persons, structures, and private and public property. Rev. 14, 2007 71

• Provisions for developing and distributing a daily blasting plan covering hole diameter, spacing, loading, and delay patterns. • Provisions for disposal of explosives, blasting agents, and associated materials. d) The contractor shall provide such reasonable and adequate security as is necessary to prevent loss or theft of explosives. He shall maintain an inventory of all explosives on the jobsite, including a record of explosives received and withdrawn from the magazines. e) Blasting operations in the immediate vicinity of buildings, public roads, overhead power lines, utility services, or similar facilities shall not be undertaken until the owners and/or the operators have been notified and all necessary precautions taken for safe control of the blasting operations. f) Explosives are intentionally manufactured to explode, and when supplied with sufficient initiating energy, will do so. Furthermore, explosives will not distinguish between initiating energy supplied purposely and initiating energy supplied accidentally. Therefore, the burden of protecting explosives from accidental sources of initiating energy must rest with those who handle and use explosives. g) Only persons authorized by the Utility to do so shall use explosives or explosive material. These persons shall be qualified by training and experience in the safe handling, transporting, storing, and use of explosives and shall have a working knowledge of applicable federal, state, and local laws. Many jurisdictions require the qualified person to hold a license. These persons shall be a minimum of 21 years of age; not addicted to narcotics, intoxicants, or similar types of drugs; and able to understand and give written and verbal orders. h) Explosives and blasting caps (detonators) shall not be transported on the same vehicle, except by permission of the authority having jurisdiction. Blasting supplies shall not be transported with other materials or cargoes. i) Explosives and detonators shall be carried and transported in the original manufacturer’s container or other approved container. j) Vehicles transporting explosives, detonators, and other blasting supplies shall have any exposed spark-producing metal on the 72 Rev. 14, 2007

inside of the body covered with nonsparking material; be marked or placarded on both sides, the front, and the rear with approved “explosives” signs; be equipped with fire extinguishers in good mechanical condition; and be driven by an appropriately licensed driver. k) Motor vehicles or conveyances containing explosives, blasting agents, or blasting supplies shall not be taken inside a garage or shop. No repairs shall be performed on a motor vehicle or conveyance loaded with explosives, blasting agents, or blasting supplies. l) Motor vehicles or conveyances containing explosives or blasting agents shall at all times be attended. m) Because electric blasting caps, when not shielded by a closed metal box, have been known to be detonated by the operation of two- way radios in vehicles as well as by regular radio transmitter stations, no vehicle equipped with a radio transmitter shall be allowed within 100 feet of blasting operations or exposed electric caps, while the transmitter is in operation. n) When electric blasting caps are used, adequate signs warning against the use of mobile radio transmitters shall be prominently displayed. o) The blaster, prior to connecting the charge or initiating the explosives, shall ensure the protection of both the public and Utility employees through the use of warning signs and/or personnel stationed around the perimeter of the danger area. p) Electrical connections shall be made only after the hole has been charged and the area is clear. q) Before the blast is fired, a loud signal shall be given by the blaster who shall have made certain the area is clear of persons and extraneous materials. Blasting signals shall be posted as follows: (1) Warning Signal: A 1 minute series of long blasts given 5 minutes prior to blast signal. (2) Blast Signal: A short signal of blasts 1 minute prior to the shot. (3) All Clear Signal: A prolonged blast following the inspection of the blast area. r) In cases of misfires, no person shall return to the blast area until permitted to do so by the blaster. Misfires shall not be inspected Rev. 14, 2007 73

until a sufficient waiting period has elapsed. For nonelectric blasting, the minimum waiting period is 1 hour; for electric blasting, the minimum period is 30 minutes. s) Blasting cap leg wires shall be kept short-circuited (shunted) until they are connected into the circuit for firing. t) For additional information concerning explosives, refer to OSHA Standard 29 CFR 1910.109. Note: In addition to the above, all local, state, and federal laws covering the transportation and use of explosives shall be observed. 303 Compressed Gasses a) Care shall be exercised in handling all compressed gas cylinders. They shall not be dropped, jarred, or exposed to temperature extremes. b) Cylinders shall have the valve cap or valve protection device in place at all times, except when in actual use or connected to a welding set. c) Cylinders shall not be rolled and shall not be lifted by the valve or valve cap; a suitable cradle or other device shall be used. d) Cylinders shall have their contents properly identified. e) Cylinders not having fixed handwheels shall have keys, handles, or nonadjustable wrenches on the valve stems while the cylinders are in service. f) Compressed gas cylinders, whether full or empty, shall be stored in an upright position and chained or otherwise secured so that they cannot fall or be upset. g) When cylinders are transported by powered vehicles, they shall be secured in a vertical upright position with the valve cap or valve protection device in place. h) Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease) by a minimum distance of 20 feet or by a 5 foot high noncombustible barrier. i) Cylinders shall not be placed where they might become part of an electric circuit or within 5 feet of an electrical outlet. 74 Rev. 14, 2007

j) Hydrogen and fuel-gas cylinders shall be stored only in a separate room, compartment, building, or shelter specifically designed for that purpose as described in OSHA Standard 29 CFR 1910.253(B)(3). k) Employees shall never force connections that do not fit nor shall they tamper with the safety relief devices of cylinder valves. l) Before the regulator is removed from a cylinder, the valve shall be closed and all pressure released from the regulator. m) A leaking cylinder shall not be used.

SECTION 4 PERSONAL PROTECTIVE EQUIPMENT 401 Personal Protective Equipment (PPE) a) All employees shall be equipped with the appropriate PPE necessary to safely perform their jobs. The employer shall ensure that a preliminary assessment of work operations is performed to adequately evaluate the hazards and select suitable PPE for the employees. Any time PPE is worn, a job hazards analysis (JHA) should be completed prior to starting work. b) Before any employee is assigned a new article of PPE to use during the course of their job, training should be conducted to instruct the employee on the use, care, inspection, and maintenance of the PPE. c) When working on or near live electricity, the employer shall consider an arc hazard assessment of the electrical system. The arc hazard assessment would provide the qualified electrical workers with the flash protection boundary based upon the incident energy produced. See tables 4.1 and 4.2. 402 Eye and Face Protection Appropriate and approved eye and/or face protection shall be worn when an employee is engaged in the following work activities or when required by Utility policy: a) Drilling or chipping stone, brick, concrete, paint, pipe coatings, or metal. b) Power grinding, buffing, or wire brushing. c) Flame welding, cutting, or burning (approved colored lenses shall be used). d) Hand drilling or sawing of overhead objects. e) Use of powered tools such as drills, saws, or sanders. f) Dust or flying particles (compressed air used for cleaning purposes must be less than 30 psi, and then effective chip-guarding and personal protection must be used). g) Gunniting, pouring hot lead or hot compounds, or using other hot or injurious substances. Rev. 14, 2007 87

h) Handling acids, caustics, chlorines, ammonia, or other similar liquids or gases, except when approved complete head coverings are worn (chemical goggles are necessary). i) Brush chippers. j) Thermite (cadweld) type welders. k) Flying particles caused by other workers, if employee is within the range of such particles (a suitable screen around the work may be used instead). l) Any other danger of injury to the eyes, or at the direction of a supervisor. m) Any time there is a possibility of electrical flash, or work activities (as determined by JHA) generate airborne particulates, appropriate protective shield or safety glasses shall be worn. If a worker may be exposed to an electrical hazard, all protective headwear, including prescription eyewear, must have an appropriate non- conductive rating. Refer to ANSI Z89.1-2003 for prescription eyewear purchased after July 5, 1994. The employer shall ensure employees are equipped with non-metallic prescriptive eyewear. n) While using powder-actuated tools. o) Protective eyewear appropriate for the lighting condition shall be worn. Glasses with dark lenses shall not be worn in poor lighting conditions, before sunrise or after sunset. For additional information concerning eye and face protection requirements, refer to OSHA Standard 29 CFR 1910.133. 403 Head Protection a) Approved safety head gear shall be worn by all employees in areas where falling objects, electrical contact, or other hazards may cause a head injury, and when required by Utility policy. b) Safety head gear or head band assembly shall not be defaced or altered in any manner without approval. c) Approved head shields or hoods shall be worn when welding with hydrogen, heliarc, or electric arc. d) All employees whose hair length (facial hair included) may cause a hazard when working around moving machinery or an external 88 Rev. 14, 2007

heat source sufficient to cause a fire, shall keep the hair to a safe length or wear a hair net or other device to keep the hair from causing hazards. e) For additional information concerning head protection requirements, refer to OSHA Standard 29 CFR 1910.135, ANSI Z89.1 for industrial workers, and ANSI Z89.2 for electrical workers. 404 Wearing Apparel Each employee shall wear gloves and other clothing suitable for the work performed. Rubber glove protectors shall not be used as work gloves. Appropriate footwear required for special work shall be worn as directed by the employee in charge. All employees must wear appropriate footwear for assigned jobs that will ensure minimum protection. When protective footwear is required, it shall meet the requirements of OSHA Standard 29 CFR 1910.136. (Other protective devices are to be used in specific types of work to provide adequate personal protection.) Also refer to clothing restrictions in Paragraph 405. 405 Clothing a) All employees shall always wear clothing and shoes that are suitable for the particular type of work which they are doing, and that are in compliance with Utility policy. The employer shall ensure that each employee who is exposed to the hazards of flames or electric arcs does not wear clothing that, when exposed to flames or electric arcs, could increase the extent of injury that would be sustained by the employee. As per National Electrical Safety Code (NESC)requirements, wearing appropriate clothing has been shown to limit the lasting effects of being caught in a flashover. The level of injury sustained by a worker involved in a flashover can be substantially reduced by careful selection of the clothing materials to be worn (to avoid fusing melted plastic to the skin, skin damage due to burning clothing, and unnecessary exposure of the skin to heat during a flashover.) Long sleeves are recommended and shall be worn with sleeves rolled down in order to help reduce the amount of exposure to heat on the arms. Rev. 14, 2007 89

Tables 4.1 and 4.2 are given as a guideline for evaluation of flame resistant and flame retardant clothing. A calculation should be completed by each utility to estimate arc exposure values based on their own fault current and work practice separation distance from the arc to the employee.

b) Appropriate flame retardant clothing is acceptable under conditions defined by an arc hazard assessment. Clothing made of acetate, polyester, nylon or rayon (either alone or in blends) may not be worn unless it has been adequately treated or is worn in such a manner as to eliminate the ignition and melting hazards. An electrical safety hat with appropriate protective shield or safety glasses (see Eye and Face Protection, paragraph 402 and Head Protection, paragraph 403) shall be worn when working on or near live parts where the possibility of an electric arc exists. The wearing of short pants when performing any type of electrical line work shall be prohibited. c) When work is performed in the vicinity of exposed energized parts of equipment, employees shall remove all exposed conductive articles such as key or watch chains, rings, or wrist watches or bands, if such articles increase the hazards associated with inadvertent contact with the energized parts, moving equipment, and to avoid pinching, crush hazards, and being caught on or in something such as with loose clothing. Loose clothing can also catch on exposed hardware or extend into energized areas. d) Finger rings or unnecessary jewelry shall not be worn while climbing on or off structures or vehicles or while performing any task where the ring might be caught under or snagged by a projecting item. Rings and wrist watches with metal case and watch bands shall not be worn while working on or near energized equipment or lines. Medical alert bracelets may be worn with transparent bands that hold the bracelets snugly to the skin. e) Each employee shall wear gloves suitable for the work. Rubber glove protectors shall not be used as work gloves. Metal articles worn under rubber gloves may provide a pressure point or chafe glove, thus increasing the opportunity for failure at that point. f) Due to the potential for heat-related illness when wearing protective clothing in ambient temperatures greater than 78 degrees F, employers shall provide employees additional awareness training regarding the recognition and prevention of signs and symptoms of heat-related illness. (Refer to the American Conference of Governmental Industrial Hygienists 2007 Threshold Limit Value’s and Biological Exposure Indices Manual) 92 Rev. 14, 2007

g) Employees shall refer to Utility policies for additional clothing requirements. 406 Use and Care of Rubber Gloves Note: Supervision or Utility rules may require the use of rubber sleeves in addition to rubber gloves. a) The use of rubber gloves shall be in accordance with the following table: Table 4.3 Maximum-Use Voltage for Rubber Gloves Class of Glove Voltage, V (RMS) Phase-Phase 00 500 0 1,000 1 7,500 2 17,000 3 26,500 4 36,000 The maximum use voltage is the ac voltage (rms) rating of the protective equipment that designates the maximum nominal design voltage of the energized system that may be safely worked. The nominal design voltage is equal to the phase-to-phase voltage on multiphase circuits. Exception 1: If there is no multiphase exposure in a system area (at the worksite) and the voltage exposure is limited to the phase (polarity on dc systems) to ground potential, the phase (polarity on dc systems) to ground potential shall be considered to be the nominal design voltage. Exception 2: If electric equipment and devices are insulated, isolated, or both, such that the multiphase exposure on a grounded wye circuit is removed and if supplemental insulation (e.g., insulated aerial device or structure-mounted insulating work platform) is used to insulate the employee from ground, then the nominal design voltage may be considered as the phase-to-ground voltage on that circuit. Courtesy of National Electrical Safety Code 2007, Table 441-6 b) Voltage shall be considered to be phase-to-phase voltage unless all conductors except the one being worked are insulated (with Rev. 14, 2007 93

protective devices) or isolated so that physical contact cannot be made with any energized part. In that case, phase-to-ground voltage will determine maximum-use voltage. c) Rubber gloves are recommended to be worn while working on any pole or other structure on which energized lines or equipment are located, on which lines and equipment that could be energized are located, or that are located close to energized lines or equipment where an employee could make contact (see paragraph 507.1 for limits on voltages 5kV or more). The rubber gloves should be put on before the employee ascends a pole or structure or raises an aerial device off the ground or device’s cradle. Furthermore, employees should not remove the gloves until they have descended the pole or structure or returned the aerial device to the ground or cradle. As a minimum requirement, gloves shall be put on before the employee comes within falling or reaching distance (based on the AC Live-Line Work Minimum Approach Distance as indicated in Table 5.2) of unprotected energized circuits or apparatus or those that may become energized, and they shall not be removed until the employee is entirely out of falling or reaching distance of such circuits or apparatus. Employees shall refer to Utility policy regarding additional rubber glove requirements. d) In addition, rubber gloves shall be worn during the following conditions: (1) Working on or within falling or reaching distance of conductors, electrical equipment, or metal surface (crossarms, crossarm braces, or transformer cases), which are not effectively grounded and which may be or may become energized. (2) During wet or stormy weather, working on or within falling or reaching distance of any conductor or equipment that may be or may become energized at any voltage. (3) Required by supervision. (4) Removing lead sheath and sleeves from cables and joints and opening or cutting cables (until they have been proven to be de-energized at the work location by positive tests). (5) Performing tests on cables using approved testing devices. 94 Rev. 14, 2007

(6) Operating manually controlled air-break switches. (7) Opening and closing manually operated oil circuit breakers. (8) Using approved switch sticks or live-line tools for opening, closing, removing, or replacing hot clamps, fuses, or fuse doors on cutouts or when making or breaking any circuit and during inclement weather. (Exception: gloves may not be worn when using an extendo stick from the ground at a minimum of 20 feet.) (9) Using approved switch sticks or live-line tools for making tests to determine if lines are de-energized, in applying and removing grounding devices, and during incle- ment weather. (10) Working on or near series street lighting circuits even though they are disconnected from the source of power. (11) Repairing series fixtures or attachments, the circuit of which is exposed to energized conductors, except where the fixtures are disconnected from the line. (12) Pulling in wires or handling other conducting materials near circuits, apparatus, or equipment that is or may become energized. (13) Working on or near telephone or other circuits that are subject to induced voltages from energized high voltage circuits, unless such circuits to be worked are adequately grounded. (14) Making physical contact with protective devices installed on energized conductors. While setting or removing poles between or near conductors energized above 600 volts, observe the following: (i) If safe clearance cannot be maintained, the conductors shall be de-energized or covered with protective devices and spread, or pole guards shall be used to minimize accidental contact. (ii) Workers handling the butt of the pole shall wear rubber gloves whether or not cant hooks, peaveys, or slings are used. Rev. 14, 2007 95

(iii) Until a pole is positively secured from moving against an energized conductor, no one shall step on or off the truck or touch any part of it without using rubber gloves, if the employee is standing on the ground. (15) Also refer to Paragraphs 509.9. Note: “Reaching distance” includes the employee’s reach as extended by handling conductive material and/or work equipment. e) Rubber gloves shall never be worn inside out. They shall be exchanged any time they become damaged or the employee to whom they are assigned becomes suspicious of their condition. Leather protection should be worn over insulating gloves except as follows: (1) Protector gloves need not be used with Class 0 gloves under limited use conditions, where small equipment and part manipulation require unusually high finger dexterity. In this case, extra care will be needed in the visual examination of the glove and in the avoidance of handling sharp objects. (2) Any other class of glove may be used for similar work without protector gloves if the possibility of physical damage is small and if the class of glove is one class higher than that required for the voltage involved. Insulator gloves used without proper protector gloves may not be used at a higher voltage until tested. f) Leather protectors or overgloves shall not be worn except over rubber gloves. Their use shall conform to the following table: 96 Rev. 14, 2007

Table 4.4 Minimum Distance Between Protector Gauntlet and Cuff or Rubber Glove Minimum Distance Class of Rubber Glove (inches) 0 1 1 1 2 2 3 3 4 4 g) Rubber gloves shall be inspected and given an air test before each day’s use and immediately following any incident that could reasonably be suspected of having caused damage. h) Gloves, when not in use, shall be kept in canvas bags or other approved containers and stored where they will not become damaged from sharp objects or be exposed to direct sunlight. They shall never be folded while stored nor shall other objects be placed upon them. i) Rubber gloves shall be stored in the glove bag with the cuffs down to permit drainage and better ventilation and to reduce the possibility of damage. j) Rubber gloves shall be produced by a seamless process and will be marked with the appropriate class and type.

During the test procedure, each employee will use insulating equipment and shall be isolated from any hazards involved. h) Grounding Electrode: When grounding electrodes are used, such electrodes shall have a resistance to ground low enough to remove the danger of harm to personnel or permit prompt operation of protective devices. i) Grounding Tower: Grounding to tower shall be made with a tower clamp capable of conducting the anticipated fault current. j) Ground Lead: A ground lead, to be attached to either a tower ground or driven ground, shall be capable of conducting the anticipated fault current and shall have minimum conductance of No. 2 AWG copper. k) Lifting equipment, bucket and material handling trucks, digger/derricks line trucks, shall be bonded to an effective ground or considered energized and barricaded when used near energized equipment or lines. Employers may elect to barricade lifting equipment, bucket and material handling trucks, digger/derricks line trucks, instead of bonding to the best available ground. In either case a physical barricade must be in place to keep employees or the general public from coming in contact with the equipment. When installing truck grounds, the employee installing the ground must use a hand line to raise and lower the ground. l) When a ground is to be attached to a line or to equipment, the ground-end connection shall be attached first, and then the other end shall be attached by means of a live-line tool. m) When a ground is to be removed, the grounding device shall be removed from the line or equipment using a live-line tool before the ground-end connection is removed. Rev. 14, 2007 159

n) When work is performed on cable at a location remote from the cable terminal, the cable may not be grounded at the cable terminal if there is a possibility of hazardous transfer of potential should a fault occur. 507.14 Equal Potential Grounding a) A chain binder, with provisions for attaching a personal protective ground, shall be tightened around the pole at a position below where the lineman will place his feet. b) A personal protective ground shall be attached to the chain binder and extended to the system neutral. If the neutral is not present or cannot be approached safely, refer to Paragraphs 507.13-h and 507.13-i for alternate grounding. c) Personal protective grounds shall be extended from the chain binder to a single phase, and from that phase to the other phases in a short circuit fashion. d) When work is completed, the personal protective grounds shall be removed in reverse order of installation. e) When a circuit is to be opened (e.g., opening jumpers at a junction pole or cutting slack), a temporary personal protective ground shall be installed across the open point. f) When it is not practical to use single-point grounding at the pole where work is to be performed, such as when wires are down, grounds shall be installed on both sides of the work location but not further than adjacent structures. 507.15 Pole Temporary Storage a) If it becomes necessary to store poles at the location where they are to be set, they shall be so placed that they will not interfere with traffic. b) If poles left on or near streets, highways, or walkways overnight create a hazard, they shall be safeguarded by red lights or well-lighted warning signs. c) Poles shall be so placed or blocked that they will not roll. d) Employees shall not remain on a pole pile while poles are being hoisted. 160 Rev. 14, 2007

e) Poles, loaded on a truck or trailer, shall be securely fastened every 10 feet to the truck or trailer. f) When a load of poles is within working distance of the ground, load binders shall be so installed that they can and will be operated by employees while standing on the ground. g) Employees shall not ride pole dollies or trailers. h) The wheels of the transporting vehicle shall be chocked and securely braked prior to loading or unloading. i) Refer to Paragraph 503.8 for additional requirements on hauling poles and ladders. j) Poles--Average Weights (When furnished to A.S.A. specifica- tions): Poles, even within the same class, vary in diameter and, hence, weight. Also, the moisture content of a pole changes under various conditions. Therefore, while weights given in the following tables should be taken as average values only, they should prove sufficiently reliable. Refer to Tables 5.9, 5.10, and 5.11. 507.16 Setting and Removing Poles a) If any holes are left unfilled at the end of the work period, they shall be protected with substantial coverings. b) All persons not engaged in pole-setting operations shall keep out of the work area. c) No one shall be on a gin pole when it is being used to raise another pole. d) While setting or removing poles between or near conductors energized above 600 volts, observe the following: (1) Ground wires should not be attached on the pole being set or removed from an energized line higher than ten feet from the ground. (2) If safe clearance cannot be maintained, the conductors shall be de-energized or covered with protective devices and spread, or pole guards shall be used to minimize accidental contact. (3) Workers handling the butt of the pole shall wear rubber gloves whether or not cant hooks, peaveys, or slings are used. Rev. 14, 2007 161

(4) Until a pole is positively secured from moving against an energized conductor, no one shall step on or off the 162 Rev. 14, 2007

Long sleeve shirts are recommended during the setting and removing of poles to minimize the amount of exposure through skin contact. 166 Rev. 14, 2007

Figure 5.4 Suggested Standard Signals for Line Work Signal 1 is used to indicate the direction of pull. Faster or slower motions of this signal are used to indicate speeds other than caution or slow speeds. Where there is a choice of conductors to be pulled, this signal is given with one of the indicating Signals 7-12, inclusive. Signal 2 always follows either Signal 1 or Signal 4 and is an indication of slow speed for caution. This signal must be given continuously while the pull is being made at slow speed and is to be terminated by either giving Signal 1, Signal 4 (depending on direction), or Signal 3. Signal 4 is used to indicate the direction of pull and is used in slacking or lowering as Signal 1 is used for taking up. Signals 7-12 are always used in connection with either Signal 1 or 4 and are given at the same time either Signal 1 or 4 is given. In using Signals 10, 11, and 12, the person’s arm on the wire side to be pulled is used for the indicating signal. Rev. 14, 2007 167

a) If a system operator is in charge of the lines or equipment and their means of disconnection, the following steps shall be taken: (1) A designated employee requests that the system operator de-energize the equipment. This designated employee becomes the employee in charge and is responsible for the clearance. (2) All switches, disconnectors, jumpers, taps, and other means through which known sources of electric energy may be supplied to the particular lines and equipment to be deenergized shall be opened. Such means shall be rendered inoperable, unless its design does not so permit, and tagged to indicate that employees are at work. (3) Automatic and remotely controlled switches that could cause opened disconnecting means to close shall be tagged at the point of control. (4) Tags shall prohibit operation of the disconnecting means and indicate that employees are at work. (5) After the above steps have been taken, the equipment to be worked shall be tested to ensure it is de-energized. (6) Protective grounds shall be installed (refer to OSHA Standard 29 CFR 1910.269(n)). (7) The equipment may now be worked as de-energized. (8) If two or more independent crews will be working on the same lines or equipment, each crew shall independently comply with the above steps. (9) Transfer of clearance shall be communicated to the system operator and the employees in the crew. The new employee in charge shall now be responsible for the clearance. (10) Clearance release requires the employee in charge to notify the employees under his direction that the clearance is to be released, determine that employees in the crew are clear of overhead lines and equipment, determine that protective grounds have been removed, report this information to the system operator, and release the clearance. (11) The person releasing the clearance shall be the same person who requested it, unless the responsibility has been properly transferred. Rev. 14, 2007 175

(12) Tags may not be removed unless the associated clearance has been released. (13) Only after all the above have been successfully accomplished, may the lines and equipment be re-energized. b) If no system operator is in charge of the lines or equipment and their means of disconnection, one employee in the crew shall be designated as being in charge of the clearance. The employee in charge shall then take the place of the system operator and complete steps (2) through (13) above. c) If only one crew will be working on the lines or equipment and if the means of disconnection is accessible and visible to and under the sole control of the employee in charge, then steps (1), (3), (4), (8), and (12) under a) in this section need not be taken. d) For more information, refer to OSHA Standards 29 CFR 1910.269 and 29 CFR 1910.147. 508 Tree Trimming 508.1 General a) The qualified utility arborist in charge before the start of each job shall perform a job briefing.

If a one call service is not available, each individual utility shall be contacted. (2) The person in charge shall conduct a visual inspection of the jobsite looking for conditions that indicate there may be buried utilities or other obstructions in the bore path. Conditions may include: buried utility notices, utility using facilities without overhead lines, gas or water meters, junction boxes, drop boxes, pad-mounted transformers, light poles, manhole covers, sunken ground, or any other irregularity that may indicate previous trenching. (3) The person in charge shall check to see that all utilities marked by other organizations look reasonable and that none appear to be overlooked. If locating equipment is available, spot checks of the locations flagged by others shall be made. If there is a doubt as to the location of a buried utility, the utility should be hand excavated to determine the exact location. (4) One or more of the following boring methods shall be used when operations are within 10 feet of a utility. When practicable, all three should be used: (a) Expose the utility along the bore path by careful hand digging or soft excavating. (b) Have the utility shut down during the boring operation, and upon completion, tested prior to Rev. 14, 2007 201

turning on the service to ensure the utility has not been damaged during the operation. (c) Use a steerable, tracked boring system and electrical strike system. i) During premobilization inspection, employees shall: (1) Check electronics before leaving the facility and follow manufacturer’s instructions regarding calibration. (2) Replace missing or damaged safety shields and safety signs. (3) Inspect boring machine and check all fluid levels before leaving the facility. Look for loose chains, hydraulic leaks, fuel leaks, trailer tires, etc. Make sure all safety equipment is tested and available for use. (4) Check trailer connections--safety chains, electrical connections, electric breakaway, trailer hitch, trailer brakes, and chain binders on boring machine. (5) Before transporting equipment to the jobsite, inspect the site and note the overall grade or slope, including hills, ditches, and trenches. Consider the size of the area needed to set up the directional boring equipment. Also note any obstacles such as buildings, railroad tracks, and bodies of water. j) Transportation: (1) Employees shall find a safe place to park the truck and trailer and shall observe all safety rules regarding traffic control and other warnings for motorists and pedestrians. (2) If the bore is near a road or other traffic, the appropriate federal, state, and local government agencies shall be contacted to determine the safety precautions and regulations to be observed. Appropriate traffic control shall be maintained as required. k) Setup: (1) The directional boring machine shall be firmly anchored on a level boring surface. If a level boring surface is not practicable, the directional boring machine shall be set up with the rod stack on the uphill side. 202 Rev. 14, 2007

(2) Consideration shall be given to existing underground utilities or other obstructions when stacking the boring machine. (3) All boring equipment shall be properly barricaded, as required, to keep spectators away.

(6) Applicable personal protective equipment, including but not limited to, hardhats, safety glasses, dielectric boots and dielectric gloves rated for the voltages involved, shall be worn by employees. l) Bore Operations: (1) Supervisors shall review jobsite hazards, safety and emergency procedures, and individual responsibilities with all personnel before work begins. (2) Employees shall know the right-of-way and depth tolerances and take into account the backreamer diameter when planning the bore path. (3) Employees shall use appropriate manufacturer recommended tools to tighten drill housings, backreamers, etc. Pipe wrenches, which can slip and fly off the rod causing serious injury, shall not be used. (4) The drill string shall never be rotated when a wrench is attached to the pipe. Automated wrenches shall be used when possible. (5) When backreaming and pulling in product, employees shall use extreme caution to keep loose clothing from becoming entangled. (6) Railroad track signals, traffic signal loops, high voltage power lines, and other sources can affect electronic locator operation. Employees shall identify and resolve interferences before starting boring operations. Rev. 14, 2007 203

(7) While drilling and backreaming, employees shall make sure good water flow exists. Fluid cools the head electronics and reduces the amount of force required to bore. (8) Employees shall lubricate drill pipe threads and keep threads free of dirt and debris. (9) Employees shall inspect drill pipe for signs of damage, wear, or fatigue, and replace damaged or worn pipe before a break occurs. (10) Locating, removing head, installing backreamer, pullback process, and hooking up service all require good communication. Radios or other effective means of communication shall be used. (11) Cold weather has an effect on boring machinery and electronics. Employees shall follow manufacturer’s requirements when boring in cold conditions. (12) Employees operating the boring machine shall stop and investigate any sudden change in boring rate or anything that “doesn’t feel right.” m) Electrical Strike Protection: (1) Dielectric hightop boots and gloves rated for the voltages involved shall be worn at all times by the boring crew and locator to reduce the probability of injury. Pantlegs shall be tucked on the inside of electrically insulated boots. (2) Electrically insulated sleeves shall be used when energized parts are not insulated from the employee or when employee’s upper arms are exposed. (3) Employees shall never bore near any power source in excess of the rating of the dielectric boots and gloves they are wearing. (4) Leather protectors shall always be worn over insulating gloves to provide protection. (5) As an added precaution, the locator shall stand 10 feet to the side of the bore path while the bore is progressing. (6) When the directional boring machine requires ground contact by employees to operate, a grid system of wire mesh mats that is electrically bonded to the drill unit, and 204 Rev. 14, 2007

appropriately covers the working areas of the operator and assistants, shall be used in accordance with the manufacturer’s specifications. (7) Barriers should be placed at least 6 feet away from all equipment that is electrically bonded. This shall include directional boring equipment, truck, trailer, entrance trench, exit trench, and bore path. (8) A ground rod shall be driven and securely connected to the boring machine by a heavy-duty cable. If feasible, the ground rod shall be driven at least 6 feet away from the boring machine. (9) If the boring machine is equipped with a voltage limiter, the voltage stake shall be placed at least 6 feet away and must not touch any other part of the equipment. (10) Dielectric hightop boots and gloves rated for the voltages involved shall be worn by employees while installing grounding rods and voltage stakes. (11) Sledgehammers shall not be used to install ground rods or voltage stakes; approved rod drivers shall be used. (12) Each directional boring machine should have a strike detection system that includes a voltage stake, voltage limiter, and an electrical strike indicator. The electrical strike indicator should consist of dual detection sensors, reset feature and self-test circuit. (13) Electronic strike sensing systems shall be tested prior to each use. (14) All portions of the boring system shall be electrically bonded to reduce the likelihood of their damage from high voltage differentials. n) Procedure in Event of an Electrical Strike: Note: The following are guidelines; the specific equipment manufacturer’s instructions shall be followed. (1) A strike sensing system has both test and reset capabilities. If the machine does not have both elements, the crew cannot be certain the boring machine is not still energized after an electrical strike. For directional boring machines without an adequate strike sensing system, the best Rev. 14, 2007 205

policy would be to stay on the machine or grid until the utility has shut down electricity to the area. (2) The operator shall warn the locator and bystanders to stay away. (3) For directional boring machines with both test and reset capabilities, the following procedures shall be used: (a) Do not step off the machine or grid mats and do not allow anyone to approach the work area. (b) Move the drill head or backreamer away from the contact in hopes of disengaging it from the power source. (c) Do not attempt to add or remove joints from the drill string. Breaking off the drill string can result in a lethal touch potential between it and the rest of the drilling unit. (d) Attempt to reset the strike sensing control box. If it resets, go through its operational test. This verifies the current and voltage sensing circuits were not damaged during the strike. (e) If the alarms continue after resetting, the drill string probably remains in contact with the power cable. (f) Wait 1 minute or more for the utility’s automatic reset breakers to complete all attempts to clear the short circuit. If the strike sensing system is operational and alarms remain off, the crew may leave the work area to notify the proper utility company. Employees shall not resume work without the power company’s permission. (g) If one cannot be sure the boring unit is no longer energized, have a person outside of the work area contact the proper utility company to shut off the line before anyone moves from their position. o) Procedure in the Event of a Gas Line Strike: No warning system tells directional boring crews that a gas line has been struck. Usually, the only indicator is the odor or sound of 206 Rev. 14, 2007

leaking gas. If a natural gas line is struck, use the following procedures: (1) Stop the machine’s engine immediately. (2) Instruct the crew and others to leave the area immediately. (3) Contact the gas utility. (4) Call emergency personnel. (5) Barricade the area off to keep spectators away. (6) Do not let anyone return to the area until the utility company indicates that it is safe to return. p) Procedure in the Event of a Fiber-Optic Strike: (1) Warn people nearby that a strike has occurred. (2) Contact emergency personnel. (3) Contact utility company. (4) Do not look into the ends of fiber-optic or unidentified cable. Vision damage can occur. (5) Do not resume work until given permission by utility company. 509.12 Pulling Cables a) Employees shall not handle pull wires or pulling lines within reaching distance of blocks, sheaves, winch drums, and takeup reels. b) Pull wires, steel pulling lines, or metal rodding shall not be pushed through ducts where energized equipment is present unless another employee is stationed at the other end of the run. c) Employees shall not remain in a manhole or vault during pulling operations involving heavy pulling strains unless they can take a position clear of the pulling line. 509.13 Moving Energized Cables a) Special care shall be taken when moving cables operating at voltages greater than 600 volts and then only when all other methods of movement (such as de-energizing) have been eliminated. A careful inspection of the cable to be moved shall take place before movement occurs. If cracks, voids, insulation damage or leaking oils are detected during the inspection, the cable shall not be moved in an energized state. All portions of the cable that are subject to damage must be Rev. 14, 2007 207

clearly visible. Appropriate electrical protective equipment and live- line tools must be chosen and used during this operation. b) All cables operating at voltages less than 600 volts may be moved at the discretion of the supervisor. They shall not, however, be moved if such movement require changing bends. c) All energized cables shall be handled with rubber gloves except when applying fireproofing materials. d) Energized cables that are moved shall be inspected for defects. 510 Generating Stations 510.1 General a) Visitors or uninstructed workers shall be accompanied by a qualified employee in stations and around Utility properties when life, service, or property might be endangered. b) All employees entering an attended station, except employees regularly working at such station, shall immediately report their presence or purpose according to plant procedures. c) When working on or near exposed energized lines and equip- ment, employees shall adhere to requirements of Paragraph 507.1. d) Employees shall not work on gauge glasses until pressure has been relieved. Gauge glasses shall be pressurized carefully with only authorized personnel present. e) All control, annunciator, and indicating light circuits on the back of control gauge boards shall be considered as energized. Employees working in back of these boards shall use precautions to guard against contact with exposed energized parts. Caution shall be exercised when disconnecting, blowing down, or draining gauge lines to prevent contact with exposed electrical equipment. f) Should the water in the boiler become so low that it is not visible in the water column, the furnace fire shall be extinguished and other procedures followed as recommended by the manufacturer. g) When prolonged welding or burning is to be done in the boiler drum, auxiliary ventilation shall be used. h) On all water tube boilers where drums are equipped with manheads at each end, both manheads shall be removed from each drum before workers enter the boiler. For inspection purposes, only 208 Rev. 14, 2007

one manhead need be removed if a worker is stationed outside during periods of inspection. For drum entry, the requirements of Paragraph 201, Confined or Enclosed Spaces, shall be met. i) Steam lines shall not be worked on while under pressure except for repacking valves or peening pinhole leaks. j) The following rules shall apply to steam leaks: (1) Leaky manhole covers, handhold plates, and bolted flanges shall not be worked on under pressure without specific approval. (2) In the event there is a steam line rupture or leak, an employee should not move until the source and direction of the leak can be determined. (3) All employees shall stay clear of steam leaks or ruptures. The area shall be adequately barricaded off until the system is isolated or repaired. (4) An employee shall not in any instance use any part of his body to check for steam leaks. (5) When it becomes necessary to check for steam leaks, a wooden dowel with a cloth attached, mirror or piece of metal shall be used. k) Before entering the furnace or gas passes of a boiler, the following precautions shall be taken: (1) All fuel shutoff valves shall be closed, physically rendered inoperative, and tagged with a Hold Card.

For additional information on working near exposed energized lines and equipment, refer to Paragraph 507.1. 510.2 Entering Confined Spaces a) Before employees enter a confined or enclosed space, they shall notify their supervisor and shall see that all valves, switches, control devices, and other operating mechanisms have been so positioned, physically rendered inoperative, and tagged with Hold Cards as to prevent closing the exit opening, energizing electrically, evacuating the air, or flooding the space with steam, gas, water, or anything else that may endanger their lives or health. b) To prevent the latching of self-locking doors or hatches while employees are working inside confined spaces, the locking devices shall be made inoperative or the doors (hatches) shall be secured in the open position. c) Only authorized employees shall be allowed to work inside a furnace, boiler drum, pressure vessel, tank, or similar structure. d) Before anyone enters a boiler drum, all valves, including blowdown valves, feedwater valves, steam valves, and fuel valves, shall be closed tightly and approved Hold Cards displayed (one on each of the blowdown valves and one at each of the water inlet valves). These cards shall not be removed until all work on the boiler has been 210 Rev. 14, 2007

completed; all men are out of the boiler; and all handhole, manhole, and heater plates have been replaced. Refer to Paragraph 202 and your utility clearance procedures. e) Only circuits with approved low voltage (6-12 volts) or GFI (ground fault interrupter) power supplies for lighting shall be used in boiler drums, boilers, pressure vessels, and tanks. These circuits shall have extension cords of sufficient length so that the transformers and power supplies are located outside the wet areas at all time. f) Before dismantling valves, flanges, and similar apparatus associated with boilers, pressure vessels, or pressure piping, the pressure shall be relieved and the equipment adequately drained. g) Employees shall not smoke or use open flame in boiler while protective coating containing flammable liquids is being applied. Only explosion proof lamps shall be used. h) Refer to Paragraph 201 for additional confined and enclosed space requirements. 510.3 Boiler Plant a) Waterwall ring header and economizer blowdown valves shall not be operated while the boiler is under load or being fired with other than ignition or pilot torches. b) Should a blowoff line break, a tube fail, or some similar serious leak develop, the fire shall be drawn or retarded immediately and other procedures followed as recommended by the manufacturer. c) When the blowdown line of a boiler being worked on is connected to a common blowdown line with other boilers and it becomes necessary to open the blowdown valves of the boiler being worked on, a Hold Card shall be attached to the blowdown valves and the valves physically rendered inoperative from all boilers. These Hold Cards shall not be removed until the valves of the boiler being worked on have been reclosed. Refer to Paragraphs 202 and your utility safe clearance procedure. d) Employees shall not work on safety valves while the boiler is under pressure except to make necessary adjustments, nor shall they work near unvented safety valves while the boiler is under pressure.

The following precautions shall be observed with these systems: (1) Employees shall not disconnect any fiber-optic cable or splice and stare into the optical connectors terminating the cables because of the potential for eye damage. (2) Under no circumstances should an employee who has not satisfactorily completed an approved training course perform lightwave/fiber-optic operations. (3) Because viewing lightwave emissions directly with an optical instrument, such as an eye loupe, greatly increases the risk of eye damage, an appropriate label must appear in plain view on the front of the main frame or fiber-optic termination/interconnection equipment identifying this hazard. 226 Rev. 14, 2007

c) During service, maintenance, or restoration work, a lightwave transmission system can no longer be considered enclosed. Under such conditions, employees shall observe the following: (1) Only authorized, trained employees are permitted to perform service, maintenance, and restoration work. Employees shall avoid exposing the eye to emissions from unterminated, energized fiber-optic connectors at close distances. The connectors associated with lightwave regenerators are normally recessed, thereby limiting the exposure distance. Under normal conditions, the regenerators can be removed or replaced without fear of eye injury. However, employees performing the removal or replacement work shall not stare or look directly into the vacant regenerator slot with optical instruments or magnifying lenses. (2) Only authorized, trained employees are permitted to use lightwave test equipment during installation/servicing work, since this equipment contains semiconductor lasers. (3) Unauthorized employees shall be excluded from the immediate area of lightwave transmission systems during installation and service work. The area shall be properly barricaded and posted. d) If a fiber-optic cable breaks or is removed from its normal position, employees should observe the following precautions: (1) Do not examine or stare into broken, severed, or disconnected fiber-optic cables. (2) Report any cable problems to your supervisor, who can arrange for authorized, trained installation/service personnel to repair or replace the cables. e) Employees who install, operate, maintain, or repair fiber-optic systems have, in addition to normal safety precautions, the following responsibilities: (1) Observe all Utility rules, procedures, and practices established for the safe operation of these systems. (2) Notify a supervisor immediately of conditions or practices that may cause potential personal injury or property damage. Rev. 14, 2007 227

(3) Report to a supervisor immediately any known or suspected accidental exposure to laser radiation. (4) Use appropriate safety glasses and gloves when working with fiber-optic systems. (5) When using an ultraviolet lamp for curing adhesive during splicing of fiber-optic material, only approved eyewear shall be worn. (6) Employees shall always treat every fiber as active and when using laser, take the appropriate safety precautions. (7) Eating or drinking in the fiber work area is prohibited. (8) Employees shall be informed not to rub eyes or use the restroom without washing hands first. (9) Do not assume that fiber-optic cable does not pose an electrical hazard. The fibers themselves are dielectric, but if the cable contains any metallic parts at all, the cable is conductive and should be treated accordingly. (10) Always apply temporary grounding and bonding harnesses to the cable while working with it. (11) Solvents and chemicals used for stripping fibers and cleaning shall be used in adequately ventilated areas. f) Cleaved glass fibers are very sharp and can pierce the skin easily. Do not let cut pieces of fiber stick to your clothing or drop in the work area. Use tweezers to pick up cut pieces of the glass fibers and place them on a loop of tape kept for that purpose. g) Employees shall wear safety glasses and gloves when handling fibers. h) When using tools such as hook blades to strip cable, employees shall guard against the blade slipping and cutting their hands and arms. i) When using diagonal cutters to cut or trim the metallic strength members of the cable, do not cut more than one strand member at a time and be sure to hold the portion to be cut as close to the floor as possible away from other people. j) When using razor blades for light trimming operations, always cut away from body, do not use a dull blade, do not attempt heavy cutting with a razor blade, and dispose of razor blade properly. 228 Rev. 14, 2007

k) When using utility knives for heavier cutting operations, always cut away from the body, never use a dull blade, and hold the knife in one hand and the cable with the other. l) Fiber cable sheath ease of removal is contingent on temperature. Use extra caution in colder temperatures. 511.2 Radio Frequency Radiation a) Utilization of Radio Frequency (RF) Source Equipment Which Meets Applicable Safety Standards: (1) RF source equipment shall meet all Federal Communication Commission (FCC) RF regulations and other applicable safety standards. (2) FCC certification will be required on all future purchase orders for RF amplified equipment. (3) Any service, modification, or action that has been performed on equipment that is responsible for amplifying or coupling amplified signals will be checked with RF survey equipment immediately after service and before returning that system to operational status. b) RF Hazard Identification and Periodic Surveillance: (1) Screening measurements shall be completed to identify potentially hazardous RF areas. More complex measurements may be necessary when employee exposures approach FCC established maximum permissible exposure (MPE) limits. (Refer to Table 5.13.) (2) Conducting objects in close vicinity shall be evaluated to ensure that they do not constitute RF shock and burn hazards. (3) Surveys of RF levels shall be conducted during the development of work practices to ensure they are effective in preventing excessive exposures to RF radiation. (4) Appropriate work practices must be followed during the repair and maintenance of RF equipment. (5) Surveys of RF levels shall be conducted to ensure that personal protective equipment is applicable and effective for the specific worksite conditions. Rev. 14, 2007 229
