Question

which of the following poses a significant struck - by - flying - object hazard to employees? cleaning up loose debris within a wrecker’s swing radius using a pneumatic nail gun to lay shingles

Explanation:

To determine the correct answer, we analyze the two options:

1. Option 1: Cleaning up loose debris within a wrecker’s swing radius

A wrecker (e.g., a crane or lifting device) has a swing radius where objects or the equipment itself can move. However, loose debris here is not typically “flying” in the sense of being propelled with force.

1. Option 2: Using a pneumatic nail gun to lay shingles

Pneumatic nail guns propel nails at high speed. If a nail misfires, or debris is ejected, the flying nail (or object) poses a direct struck - by - flying - object hazard, as the nail is actively launched (flying) during operation.
