If the boom is struck or damaged, what is the safest course of action?

• A. Lower the load if possible and wait for an assist crane to lower it safely.
• B. Lower the load immediately without assistance.
• C. Continue lifting and adjust later.
• D. Ignore the damage and proceed.

Answer: (A)

Damaged or struck boom means the crane's main structural member may have weakened or become unstable, so you must stop lifting and bring the load down in a controlled, supported way. The safest course is to lower the load if you can do so safely and wait for an assist crane or qualified personnel to help lower it securely. This reduces the stress on the damaged boom, minimizes the chance of sudden failure or uncontrolled movement, and gives time to assess the damage and prevent a fall or tip.

Lowering immediately without help, continuing to lift, or ignoring the damage can lead to loss of control, a crane collapse, or a falling load, putting workers at serious risk.
