If only one employee is present, one end of the rope which has been passed over the strand ((shall))must be tied to the bumper of the truck, or other equally secure anchorage. The employee then ((shall))must grasp the other end of the rope and attempt to raise himself off the ground.

(3) Inspection of strand. Where strand passes over electric power wires or railroad tracks, it ((shall))must be inspected from an elevated working position at each pole supporting the span in question. The strand may not be used to support any splicing platform, scaffold or cable car, if any of the following conditions exist:

(a) Corrosion so that no galvanizing can be detected;

(b) One or more wires of the strand are broken;

(c) Worn spots; or

(d) Burn marks such as those caused by contact with electric power wires.

(1) Need for testing wood poles. Unless temporary guys or braces are attached, the following poles ((shall))must be tested in accordance with subsection (2) of this section and determined to be safe before employees are permitted to climb them:

(c) The following method or an equivalent method ((shall))must be used for testing wood poles:

(i) Rap the pole sharply with a lineman's hammer, starting near the ground line and continuing upwards circumferentially around the pole to a height of approximately 6 feet. The hammer will produce a clear sound and rebound sharply when striking sound wood. Decay pockets will be indicated by a dull sound and/or a less pronounced hammer rebound. When decay pockets are indicated, the pole ((shall))must be considered unsafe.

(ii) The pole ((shall))must be prodded below or as near the ground line as possible using a pole prod or a screwdriver with a single blade at least five inches long, driving it in at a forty-five degree angle towards the center of the pole.

(iii) Apply a horizontal force to the pole and attempt to rock it back and forth in a direction perpendicular to the line. Caution must be exercised to avoid causing power lines to swing together. The force may be applied either by pushing with a pike pole or pulling with a rope. If the pole cracks during the test, it ((shall))must be considered unsafe.

(d) The pole should be inspected for cracks. Horizontal cracks perpendicular to the grain of the wood may weaken the pole. Vertical ones, although not considered to be a sign of a defective pole, can pose a hazard to the climber, and the employee must keep his or her gaffs away from them while climbing.

(e) The presence of any of these conditions is an indication that the pole may not be safe to climb or to work from. The employee performing the inspection must be qualified to make a determination as to whether or not it is safe to perform the work without taking additional precautions.

(f) Unsafe poles or structures.

(i) Poles or structures determined by a qualified employee to be unsafe by test or observation may not be climbed until made safe by guying, bracing or other means.
