EVALUATE THE SITUATION. Call out to the victim, "Hey! Do You Need Any Help", "Are You O. K.?" If there is no response or if the victim seems stunned or dazed, prepare to do a rescue. At this point, TIME IS EXTREMELY IMPORTANT! While calling to the victim, look at the surroundings. Look for things such as the pole or crossarm being split, cracked or on fire. If the victim is in contact with an energized conductor you will need to clear him or her using rubber goods or hot stick. When evaluating the scene look at the whole scene and not just the victim.

WARNING To ensure your personal safety, you need to wear rubber gloves or sleeves and take enough other equipment to secure your position PROVIDE FOR PERSONAL PROTECTION. 

Consider turning off the electricity, but don't waste time looking for a switch, the rescue is more important. Your safety is very important to the rescue mission Without you, there will be no rescue. This means personal climbing equipment and rubber goods are in serviceable condition. Hot line tools are ready in case needed and physical condition of the pole has been surveyed. Plan your route to the victim now. To be on the safe side assume the pole is energized; unless confirmed de-energized. Leap onto the pole. No part of your body should touch the pole and the earth at the same time.

This prevents your body from providing an alternate path for the electricity. Remember, don't take chances and become a victim also. 

CLIMB TO RESCUE POSITION. Lay out the rescue rope and attach one end to a loop of your body belt. While climbing to the rescue position, be sure to climb carefully and belt in at a safe position. Clear the victim from energized conductors using rubber goods or hot sticks, then reposition yourself and determine the victim's condition. Slightly above and to one side is normally best for checking and working with the victim.

A safe and easy method used to lower the victim to the ground is shown in figure 4-81 and requires a pulley line or a handline attached to a crossarm and tied off around the victim's chest. The knot should be in front of the victim, close to one armpit. lie three half-hitches, and snug the knot so that the rope rides high on the victim's chest Take up the slack, cut the victim's safety strap, and slowly lower him or her to the ground.

MAINTENANCE OF POWER DISTRIBUTION SYSTEMS The elements, accidents, and willful vandalism are the causes of most damage to power distribution

equipment. To repair these damages, the lineman requires experience, a total commitment to safety, and the knowledge to accomplish repairs to the system as quickly and economically as possible.

MAINTENANCE OF POLES, TIMBERS, AND CROSSARMS

The maintenance required on the poles, timbers, and crossarms in a power distribution system is minimal. Normally, this equipment lasts for a period of 20 years or more. The following problems may occur, however, and create a need for maintenance action:

A pole can settle and require straightening. Wood can shrink and cause all hardware to become loose and require tightening.

WOOD POLE MAINTENANCE Wood poles are treated with preservatives to prevent decay, but small organisms, insects, and fungi all contribute to the breakdown of the wood preservatives. The life of a pole can be extended by inspections and treatment, when necessary, to stop pole decay.

The inspection would normally include sounding the pole by hitting it with a hammer from belowground level to approximately 6 feet above ground to determine obvious defects. Also the pole is bored to determine the presence of internal voids. Poles with internal decay can be treated with insecticides. External decay is removed, and the area is treated with preservatives and wrapped with a moisture-proof barrier. Poles weakened excessively by internal or external decay must be reinforced or replaced.

MAINTENANCE OF HARDWARE, CONDUCTORS, ACCESSORIES, AND GUYS Other items that may require maintenance are the hardware, conductors, accessories, and guys.

Over time, guys stretch and require re-tensioning.

Insulators get dirty and require cleaning, especially around the sea where there is salt in the air. Connections become loose with age and must be re-torqued to prevent hot spots.

In time, conductors stretch and require re-sagging. Insulators crack and require replacement. OPERATOR MAINTENANCE RESPONSIBILITY

Operators must keep the vehicle or assigned equipment clean and in serviceable condition and must perform daily operator's maintenance. Equipment must be inspected daily and any defects noted to be corrected before a serious breakdown or mishap occurs. The NCF equipment is scheduled for preventive maintenance every 40 workdays. No piece of equipment can be expected to operate for 40 days without daily operator care. Many units of equipment have hourly and daily lubrication points. This lubrication is the responsibility of the operator. Operators must ensure that equipment is maintained as outlined in the operator's manuals. These manuals can be obtained from the CM shop library.

MAINTENANCE AND TESTING OF AERIAL EQUIPMENT WITH HYDRAULIC BOOM Operation of aerial equipment starts in the same way as other pieces of equipment. The operator must have a valid license, and a thorough prestart inspection must be performed. Maintenance and lubrication must be performed according to the manufacturers' recommendations and guidelines. Daily operator checks, made before placing the equipment in service and again when securing the equipment, will be kept on file for a minimum of 60 days. If the operator detects any condition that would indicate the equipment to be unsafe or unreliable for use, the equipment must be removed from service. A condition inspection, an electrical insulation test, and a load test are to be performed annually. The certifying official of the designated activity is

responsible for the certification of these inspections and tests. A copy of the certification must be posted on the equipment in full view of the operator. The original certification form is to be filed in the equipment history record file.
