What should you do if the boom of the unit you are operating comes in contact with an energized power line and there's no sign of fire?

When operating a hoisting unit, encountering energized power lines presents a severe safety hazard. The correct procedure is to remain in the cab until the lines have been de-energized. This is crucial because if you step out of the cab while the boom is still in contact with the energized lines, you risk electrocution or serious injury. The unit itself is often safer than the surrounding area because it can act as an insulating barrier between you and the ground.

Staying in the cab keeps you away from potentially hazardous ground currents that could occur if you dismount. Additionally, remaining in the cab allows for communication with emergency services or ground personnel to ensure the situation is handled correctly. Once the power lines have been confirmed de-energized, you can safely exit the cab.

It’s important to understand that attempting to leave the cab, escape the unit, or calling for help does not ensure safety and can increase the risk of harm in such situations. Remaining in the cab until the lines are safely de-energized is the established practice for ensuring the operator's safety during an electrical hazard scenario.
