What is the proper action if lightning threatens a lifting operation?

• A. Stop lifting, remove personnel from the area, secure loads, seek shelter, and resume only when conditions are safe.
• B. Ignore lightning if you can see the hazard.
• C. Continue lifting but slower.
• D. Move equipment away from area.

Answer: (A)

Lightning poses an immediate and unpredictable danger to lifting operations because cranes and rigging act as tall conductors that can attract a strike, energize electrical components, or cause dangerous load swings. When a lightning threat appears, the safe approach is to stop the lift right away, clear all personnel from the area, secure the load so it cannot move or fall, seek shelter in a sturdy building or enclosed vehicle, and wait until weather conditions are safe before resuming. Lowering the load to a stable position and setting up proper safeguards helps prevent movement or exposure if a strike occurs. Only after there is no lightning within a safe radius and it’s confirmed to be safe should lifting resume. Ignoring the hazard, continuing, or moving equipment while the storm remains present does not eliminate the risk and can result in severe injury or damage.
