If there is immediate danger of fire or explosion after power line contact, what is the dismount method?

• A. Jump off the crane at its lowest point by jumping off and landing with your feet together and not touching the crane again.
• B. Shuffle or hop away from the crane taking very small steps.
• C. Remain in the cab and wait for instructions.
• D. Dismount the crane at the highest point by climbing down slowly.

Answer: (A)

When there’s immediate danger of fire or explosion after a crane contacts a live power line, the priority is to break all contact with the energized surface and move away in a way that minimizes a path for electricity through the body. Dismount from the crane by jumping off at the lowest point, landing with both feet together and not touching the crane again. This technique reduces the risk of current traveling up from the ground into a separated limb or across a split-foot stance, which could happen if you stepped or shuffled with feet apart or kept contact with the crane.

Staying in the cab can be fatal if the vehicle or cabin remains energized. Shuffling with small steps can create a path for current through the body and the ground. Dismounting from the highest point doesn’t reliably shorten the distance to safety and keeps you in contact with energized structures longer. Jumping away from the crane with feet together and getting clear as quickly as possible is the safer approach.
