Fan blades seven feet above the floor should be guarded with openings smaller than 1 inch.

Fan blades seven feet above the floor should be guarded with openings smaller than 1 inch.

• A. Smaller Than 1 Inch Openings
• B. Exactly 1 Inch
• C. Larger Than 2 Inches
• D. No Guard Required

Answer: (A)

Guarding rotating parts is about preventing any part of the body from reaching the moving blades. Openings must be small enough that a finger or other body part cannot fit through, which helps stop injuries if someone accidentally reaches toward the shaft. For a fan blade seven feet above the floor, the same safety principle applies: the guard should have openings small enough to block finger entry, hence openings smaller than 1 inch. An opening exactly 1 inch could still allow a finger to slip through, and openings larger than that clearly increase the risk. A guard is required, so saying no guard is required would violate standard safety practice.
