What is the required minimum distance around a suspended load to protect personnel?

• A. A fixed 10-foot circle around the load with no exceptions.
• B. A floating exclusion zone determined by the operator's judgment.
• C. A 30-foot no-entry zone for all situations.
• D. Establish and enforce a clear exclusion zone around the suspended load; no personnel should be in the hazard area; barriers or per-site policy should be used.

Answer: (D)

The key idea is to create a protected area around a suspended load and keep everyone out of that danger zone. Suspended loads can move unpredictably—swing, dip, or drop—due to rigging, movement of the crane, wind, or start/stop actions. Because of that potential for sudden motion, the safe approach is to establish a clearly defined exclusion zone and enforce it. Barriers, warning devices, or site policies should be used to prevent entry, and only trained personnel who are actively involved in the lift should be allowed near the area, with clear communications and precautions in place.

A fixed distance doesn’t work because it can be too small or too large for different lifts—load weight, rigging configuration, span, and environmental conditions all change the hazard. Relying on an operator’s judgment alone or applying a universal distance would fail to address these variations, whereas a defined exclusion zone that is communicated and controlled provides consistent protection.
