A site has several structures within the potential swing radius of a crane, requiring an exclusion zone. Which of the following statements best describes the most stringent requirement for establishing an exclusion zone around a crane's swing radius when personnel are present, as per provincial OHS regulations?

Question: A site has several structures within the potential swing radius of a crane, requiring an exclusion zone. Which of the following statements best describes the most stringent requirement for establishing an exclusion zone around a crane's swing radius when personnel are present, as per provincial OHS regulations?

Answer options:

• Personnel are permitted within the swing radius if the crane is not actively swinging a load.
• An exclusion zone must be established if there is any pedestrian traffic nearby. ✅ The exclusion zone must prevent personnel from being struck by the crane's rotating superstructure, hoisted load, or anything that might fall from them.
• Only the area directly under the load requires an exclusion zone.

Correct answer: The exclusion zone must prevent personnel from being struck by the crane's rotating superstructure, hoisted load, or anything that might fall from them.

Explanation: Provincial OHS regulations emphasize preventing personnel from being struck by any part of the crane's rotating components, the load itself, or any material that could fall. Therefore, the exclusion zone must encompass this entire potential hazard area, not just the load path.
