4.14.5.1 Before beginning work with equipment near energized lines or equipment where the equipment or extension of the equipment (such as during stringing or pole setting) could become energized through direct contact with lines or equipment or through induced current from nearby energized facilities, the equipment shall be grounded to an acceptable grounding source.  The best grounding source available shall be used.

Scene 5

Scene 7

4.14.6.3 Last resort choices  -when other options are not available

4.14.6.3.1 Anchor rod, fully driven ground rod, screw anchor installed to a depth of at least 5 feet.  4.14.6.3.2 Do not connect to fences, guard rails, signposts, or any other non-approved grounding points.

Scene 8

Be sure to extend truck grounds completely and do not leave them rolled up while in use to reduce any chance of increased resistance in the ground cable. Remember; the purpose of grounding is to cause immediate operation of a circuit protective device.  In other words, the  groundman is not protected from electrical contact if the truck becomes energized. This is why we barricade the truck
