What is the purpose of an exclusion zone around the crane?

• A. To keep personnel away from the lift swing zone and potential hazards.
• B. To mark the boundaries of the crane's parking area.
• C. To measure wind velocity.
• D. To designate area for fuel storage.

Answer: (A)

Keeping people out of the crane's swing zone is the fundamental safety principle. An exclusion zone creates a barrier around the crane so workers aren’t inside the area where a load or the hoist could swing, drop, or move suddenly. This safety buffer protects against injuries from a swinging load, falling objects, or contact with moving crane parts, and it helps ensure everyone stays clear of hazards during lifts. The zone should reflect the crane’s working radius and the dynamic movement of the load, and it’s clearly marked and controlled so all personnel know where they must stay away.

This area isn’t meant for marking where to park equipment, measuring wind during operation, or designating fuel storage; those functions are handled separately, while the exclusion zone focuses on preventing access to crane-related hazards.
