Grounding a. Unless otherwise performing work with live line or other approved insulated tools, Overhead, Underground or Station conductors and equipment normally operated at a voltage in excess of 600 Volts shall not be worked on until de-energized and the normally energized parts have been tested as de-energized with an approved device for indication of voltage and all conductors have been short circuited and grounded according to business unit procedures. Backfeed from transformers, energized high voltage conductors which cross over a de-energized conductor and unprotected energized conductors which cross under a de-energized conductor shall be considered possible sources of supply. This shall not preclude the removal of grounds for test purposes. When the work on such de-energized conductors involves the wiping or testing of insulators only, high voltage conductors crossing under such de-energized conductors need not be considered a possible source of supply. b. Only approved grounding and jumper equipment shall be used. This equipment shall only be used for grounding purposes. Portable grounding devices shall be secured to permanently grounded objects at the location selected for grounding in the following order of priority: 1. Station ground 2. 4-wire multi-grounded primary neutral 3. Steel structures 4. Anchor rods If none of the foregoing are available, an approved temporary ground rod shall be used. An approved testing device shall be used to prove conductors or equipment is de-energized before grounding. The conductors or equipment shall be grounded and short circuited with approved grounding devices. Grounding devices shall be applied and removed with live line tools. When the primary neutral conductor is used as the grounding medium, grounding devices must be connected to an additional approved ground. Note: A multi-grounded primary neutral, as opposed to a "neutral of 4 kV isolated neutral system" is defined as a neutral conductor on a primary circuit, that has grounds attached to it, at intervals of up to 1,200 feet. If a multi-grounded primary neutral has grounds attached to it at intervals greater than 1,200 feet, it should be reported, however it shall still be considered a priority for grounding purposes, over steel structures, anchor rods, and driven grounds. 5. The grounding devices shall first be connected to a ground before being brought in contact with any conductor to be grounded. When being removed, they shall be removed from all conductors before being disconnected from ground. No employee shall handle any conductive portion of the grounding device while it is being installed or removed from the conductors, except when using live line tools. 6. The employee applying the grounding device shall determine that all persons are a safe distance from any portion of the grounding device before contacting the conductor with the grounding equipment. 7. Grounds shall be installed so that at least one set is visible to one member of the crew, unless one of the grounding devices is accessible only to authorized persons. 8. Grounding devices shall be placed so that employees cannot make accidental contact between the grounding devices and unprotected energized conductors. 9. When working on new lines or equipment under construction or on existing de-energized conductors or equipment, jumpers shall be installed to ensure that no potential difference exists between the equipment being worked upon and any grounded conductors or equipment which might be contacted while the work is in progress. On grounded steel structures, a personal ground shall be installed between each de-energized conductor being worked upon and the steel structure. Before opening or closing any conductor that may be exposed to a difference of potential or that has been grounded to a primary neutral, approved jumpers shall be in place across the point to be opened or closed to ensure continuity of the conductor. When splicing overhead conductors at ground level that are exposed to hazardous differences in electrical potential, an Equal Potential Zone (EPZ) mat shall be used, or a ground shall be installed on each side and within ten feet of the working area. The two ends being spliced shall be bonded together with an approved jumper. 10. When it is necessary for employees of other Business Units to work in substations or generating stations on lines or equipment where portable grounds are required they shall be supplied by the substation or generating station. 11. When work is to be done on one de-energized circuit of a multiple circuit line at the same level and the circuits are separately bonded, tests shall be made to determine that no appreciable difference of potential exists between the grounded conductor and the bond of the circuit to be worked upon. 12. When working on or climbing through energized multiple circuits that are commonly bonded and it is impossible to avoid personal contact with the bond, the bond shall first be grounded before the lineman climbs through or works on the circuit. 13. When work is to be done or contact made on the bond or metal fixture of either a Dreyfuss or squirrel cage fixture supporting energized conductors, it must be done with live line tools or the fixture must be grounded. If the bond wire is #4 copper and is exposed so it can be inspected, only one fixture need be grounded. If not, approved jumpers are required between fixtures.

Mouth-to-Mouth Resuscitation a. Introduction Mouth-to mouth resuscitation is the skill or process of providing ventilation to a victim who shows no sign of breathing, but who does show signs of circulation (pulse). Mouth-to-mouth resuscitation shall ONLY be delivered by those personnel who have received advanced training in the technique. For all other responders, if a non-breathing victim is encountered, they should immediately institute Cardiopulmonary Resuscitation (CPR) (see Rule 1015). b. Symptoms — Respiratory Arrest 1. The victim's color may be abnormal, such as: pale, ashen, bluish in appearance or, in the case of carbon monoxide poisoning, cherry red (this is a rare late sign). 2. No rise or fall of the chest cavity. c. Mouth-to-Mouth Resuscitation 1. Call Emergency Medical Service (911 or follow site-specific instructions). 2. Perform mouth-to-mouth resuscitation as follows: STEP 1. Opening the airway: Put one hand under the victim's chin and the other hand on the victim's forehead. Gently pull the chin away from the back of the throat without closing the mouth. When this is done, the jaw and tongue are drawn forward and the air passage is cleared. STEP 2. With the heel of your hand resting on the victim's forehead, bring your thumb and forefinger across to pinch the nose. Pinch the nose and breathe into the victim's mouth or nose. Pinching the nose will prevent the rescuer's air from escaping. STEP 3. After opening the airway and pinching the nose, you are now ready to breathe into the victim's mouth. Remember, you are breathing for two people, so take a deeper breath than normal. Open your mouth wide enough to encircle the victim's mouth. Air is blown into the victim's lungs until the chest expands visibly. Remove your mouth and take another breath of air while you see or feel the victim exhale. STEP 4. Each inhalation and exhalation is termed a cycle. The rhythm is 12 cycles per minute. Every five seconds, you should give the victim one breath of air. Count 1001, 1002, 1003, 1004, breathe. 3. If the victim's mouth cannot be opened, use the mouth-to-nose technique: STEP 1. Seal the victim's lips with your thumb so no air can escape STEP 2. Take an even deeper breath and blow into the victim's nose STEP 3. After approximately five to ten breaths, the victim's muscles may relax. If so, begin mouth-to-mouth which is the more desirable method of resuscitation. d. Caution 1. If the stomach balloons or expands, air is not being delivered to the lungs. The cause of this is often the speed with which the rescuers breath was forced into the lungs. Take a full 1 to 2 seconds for each breath. Release the air by applying gentle pressure with the heel of your hand on the stomach during the exhalation stage. 2. After the victim has recovered, they should be placed on their side in case they become ill and vomit. If they were to remain on their back, they could choke on vomitus matter. Clear vomitus from mouth and maintain open airway. e. Alternate Method: In rare cases, mouth-to-mouth/mouth-to-nose resuscitation cannot to be performed due to severe bleeding from the mouth, fractures of jaw, and so forth. Therefore, the back pressure arm-lift or Holger-Nielson Method should be used. 1. A rescuer kneels at the victim's head, placing hands in the middle of the victim's back. Theheels of the hands should be placed at an imaginary line between the victim's armpits, with the thumbs touching and the fingers pointing downward. Be careful not to open the hands too widely. 2. Rock forward, keeping the arms straight, exerting pressure on the victim's back. Release the pressure, then grasp the victim's elbows, applying enough lift to feel resistance. Release the elbows and continue this procedure at a rate of 12 times a minute. 3. Periodically, monitor the victim's mouth to see that it is clear of all foreign matter. After recovery, place victim on the side, cover, and treat for shock until medical help arrives.

155

214

Wire Stringing a. When stringing or taking down wires, the number of persons actually handling the wire at any one time shall be held to a minimum. Running lines, hold down lines, and tag lines shall be used and left attached until the wires are in place and properly secured. It is the duty of the employee in charge to see that such means of protection are adopted as are necessary to make the work safe. b. When stringing or taking down wire along or over streets or highways, the equipment pulling the wires shall be provided with flags, front and rear. Other precautionary measures, such as flagmen, cradles, and barriers shall be used as required. c. When stringing or taking down wires from above or below unattached energized lines or on poles or towers on which there are attached energized lines of over 600 Volts, precautions shall be taken to adequately insulate the employees from the wire or wire stringing equipment by the use of rubber protective equipment or other approved methods. Employees shall not contact wire stringing equipment in a manner which would permit their bodies to become a parallel path to ground. When conductors being pulled in or out are to be handled by employees on poles or towers, Rule 141 shall apply. In addition to the above requirements, bare wires (except bare neutrals in multi-conductor cables) shall be pulled over grounded rollers at the first pole or second pole from the payout and takeup equipment and through traveling grounds between the first pole and the payout and takeup equipment. The metal frame of the wire stringing equipment shall be bonded to the traveling ground. NOTE** Service drops are excluded from the above requirements.

209

Working in Elevated Positions a. Before climbing poles or structures, employees shall familiarize themselves with the circuits, voltages, apparatus thereon, and any unusual conditions which might present a hazard. b. Not more than one employee shall ascend or descend a pole at the same time. The first employee shall be in place on the pole or on the ground before the next employee climbs or descends the pole. When it becomes necessary for one employee to work above the other, extreme care shall be exercised. c. Before climbing poles, ladders, scaffolds, or other elevated structures, or riding span wires, messengers, or cables, or entering cable cars, boatswain chairs, or the like, employees shall first assure themselves that said structure or device is strong enough to safely sustain their weight. d. Before allowing employees to work on any pole from which supporting wires or guys are to be removed, or on which in any way the stress is to be changed, the employee in charge shall make sure that the pole will stand the change in stress without falling. If it is necessary to test the pole, see Rule 202. When the condition of the pole to be worked on is in doubt or when it is not practicable to test, the pole shall be supported before work is started. e. Employees shall observe height nail or pole brand to make certain that the pole is set to proper depth. (Manufacturers usually place their pole brand 10 feet from the butt end of the pole on 25-foot to 60-foot poles and 13 feet from the butt on all poles 65 feet or longer.) f. Employees shall not transfer from aerial buckets or baskets to a pole or structure. Transfer from an open platform to poles or structures are permitted. g. Climbers shall not be worn while performing work from an aerial lift. h. Neither the bucket nor boom shall be allowed to contact unprotected energized conductors. This does not preclude the use of attachments to the boom specifically designed to support energized conductors. i. When using power tools, grounded material or equipment such as wire, cable, personal grounds, electric cords, and so forth, approved for use on erected poles, towers, or structures, the tools and all electric supply lines connected thereto shall be kept a safe distance under the level of circuit or apparatus energized in excess of 600 Volts or shall be adequately guarded or secured in such a way as to prevent their contacting energized conductors. j. Only approved portable power saws shall be used from elevated positions on erected poles.

306

Working on De-Energized Cables a. Cable or equipment to be worked upon shall be positively identified by tags, duct location, maps or approved testing means before work is started. Work will then be performed as indicated in Rule 306, b., c., d., and/or e., as appropriate. b. Cable and equipment shall be considered energized and worked with adequate protective devices until it has been tested de-energized with an approved device for indication of voltage and grounded with approved ground devices. c. Clearances, if required, shall be obtained in accordance with established procedures.

Wounds a. Definition Blood borne pathogens (BBP): Microorganisms that are present in human blood and can cause disease in humans. Infection: Infection of a wound is characterized by tenderness, redness, warmth, swelling in some cases, fever and pus appearing on the wound. If infection develops, seek medical attention immediately. A wound is a break in the body tissue, either internal or external. 1. Open Wounds: A break in the skin. There are six types of open wounds. (a). Abrasion: This occurs when the outer layers of the protective skin are damaged by scraping. There is limited bleeding, thus allowing foreign material to remain in the wound. (b). Incision: A clean cut by a sharp object. The bleeding may be rapid and heavy, cleansing the wound of foreign matter. Incisions are usually deep and may cause damage to muscles, tendons, nerves, and blood vessels. (c). Laceration: A lacerated wound is a jagged or irregular cut, characterized by a breaking or tearing of the soft tissues. Bleeding may be rapid and extensive with destruction of the body tissues due to the tearing action. (d). Puncture: A puncture wound is produced by an object piercing the skin, creating a hole in the tissue. External bleeding is quite limited with minor punctures; however, bleeding may be moderate to severe with large puncture wounds. Infection may develop easily, with the possibility of tetanus. (e). Avulsion: An avulsed wound results when tissue is forcibly separated or torn from the victim's body. An avulsed wound if completely removed is also termed an amputation. An incised or lacerated wound, or both, will usually occur when a body part is avulsed. There will be heavy and rapid bleeding. Any time this situation occurs, the avulsed body part should be sent along with the victim to the hospital. Wrap avulsed part in a cool moist dressing. Do not freeze. (f). Impaled Objects: When an object protrudes from the wound do not remove it. Stabilize or secure with bandage in place to prevent movement of object. 2. Closed Wounds: Damage to underlying tissues without a break in the skin. Examples of these wounds are: (a). Contusions: Bruises, black eyes, and so forth. (b). Internal Hemorrhaging: Not readily evident in most cases. May involve damage to internal organs due to puncture wounds, impaled objects, or a traumatic impact. 3. Chest Wounds: An open or closed injury to the chest. (a). If you hear air, a hissing noise or see bubbles that is a sign that the chest cavity has been opened or breached. Apply pressure directly to the wound until airtight dressing can be applied (found in the First Aid Kit gauze compress). (b). If the wound extends into the chest cavity, cover opening with an airtight dressing, preferably the 24 X 72 inch gauze compress found in the First Aid Kit. (c). Place the victim with the injured side lower to assist breathing. b. Symptoms Bleeding: There are three types of bleeding the first aid responder will encounter. They are arterial, venous, and capillary. 1. Arterial: Bleeding from a cut artery occurs in spurts. The blood is bright red in color. 2. Venous: Bleeding from a cut vein can be recognized by the dark red color of the blood and the manner in which it wells or flows evenly from the wound. 3. Capillary: Capillary bleeding is the oozing of red blood, generally from an abraded surface. It may be severe, but can be readily controlled. c. First Aid Minor Wounds: All minor wounds that do not need medical attention should be treated as follows: 1. Cleanse wound thoroughly with soap and water (use antibacterial soap if available, avoid using detergent soap. Otherwise, copious amount of water is sufficient). 2. Apply antibiotic ointment if able to confirm that the victim is not allergic to it. 3. Place bandage or dressing over the wound. 4. Observe wound for signs of infection. If redness, pus, or fever develops, seek medical assistance. d. Major Wounds: There are three methods used in the control of bleeding and should be used in the following order if possible: direct pressure, elevation, and tourniquet. The tourniquet is seldom used and only as a last resort. 1. Direct Pressure: Place a sterile compress directly over the wound and apply pressure. In an emergency, pieces of clothing, rags, or gloved fingers may be used. This method is the only available method to control bleeding on the head, face, and torso. 2. Elevation: Where direct pressure is used on extremities, control of bleeding can be helped by elevating the limb. Do not elevate limb if fracture is suspected or if victim has head, chest, or neck injuries. 3. Tourniquet: Rarely used. May result in loss of limb. A tourniquet may be applied to the arms or legs only. A tourniquet should be applied only when direct pressure on the wound, and/or elevation of the limb fails to stop the bleeding. Once the tourniquet has been applied, it should not be released except on the advice of a physician. Releasing the tourniquet increases the danger of shock, blood clots, and bleeding. PROCEDURE: If the tourniquet in SCE First Aid Kit is used, follow the instructions on the box it comes in; if not proceed as follows: (a). Use a strip of cloth at least two inches wide, such as a folded triangular bandage. Do not use narrow materials such as rope or wire as these may damage the flesh. (b). Wrap the cloth or bandage tightly twice around the limb close to the wound, between the wound and the heart. (c). Tie one overhand knot in the bandage. Place a short, strong stick on top of the knot, and then tie two overhand knots on top of the stick. (d). Twist the stick to tighten a strip of cloth around the limb, until the bleeding is greatly reduced or stops. Wrap and tie in place another strip of cloth around the stick and limb so the tourniquet will not unwind. (e). Do not cover the tourniquet. (f). Attach a highly visible note on the victim indicating the location of the tourniquet and the time when applied. Place the note on the victim's clothing by the collar. e. Caution Shock: When moderate to severe bleeding is present, first aid for shock should be started as soon as possible (see Rule 1003).
