What actions should be taken if a crane contacts a power line?

• A. Stop lifting and walk away from the area.
• B. Stop lifting, attempt to manually disconnect the crane from the line.
• C. Call a supervisor and wait.
• D. Stop lifting, keep clear, contact the utility, and follow emergency and de-energization procedures; do not touch the crane.

Answer: (D)

When a crane contacts a power line, the immediate priority is life safety: stop all movement, keep everyone clear of the crane and the line, and ensure the line is de-energized by the proper authorities before anyone approaches further. Electricity can arc through the crane’s metal structure or the load, so even standing close or attempting to disconnect the line can cause severe shock or fatal injuries. The safest course is to stop lifting, step back to a safe distance, contact the utility company, and follow established emergency and de-energization procedures. Do not touch the crane, the line, or any part of the system until the utility has confirmed it is de-energized and it is safe to approach.

This approach is better because it immobilizes the potential energy source and relies on qualified personnel to safely shut off power, reducing the risk of electrocution or further electrical hazards. Other options either leave the line energized, encourage dangerous attempts to disconnect, or rely on someone who may not be authorized to de-energize the line, all of which can put people at serious risk.
