If a mobile crane contacts a power line, what should the operator do?

• A. Stay in the cab and attempt to disengage
• B. Jump out immediately
• C. Call for help and keep working
• D. Lower the load slowly

Answer: (A)

When a mobile crane contacts a power line, the immediate goal is to prevent electric shock by avoiding any path to ground. Staying inside the cab is the safest choice because the enclosed, insulated cabin helps keep you protected from energized parts and arcing. From within the cab, you should alert others and get qualified help to de-energize the line before any movement or disengagement is attempted. Exiting the cab or continuing to operate can create a dangerous ground path or bring you into contact with live metal. In this context, staying in the cab and initiating the safe disengagement process from inside (while awaiting utility intervention) is the best course of action. The other options would expose you to serious electrical hazards.
