Which item is NOT a head strap/harness inspection concern?

• A. Loss of elasticity
• B. Broken buckles
• C. Breaks and tears
• D. Cracks in facepiece lens

Answer: (D)

The main idea is to know which parts are part of the head strap/harness system and which belong to other components of the respirator. The head strap/harness is checked for wear that would affect how securely the respirator fits on your head: loss of elasticity means the strap won’t pull tight enough to seal, broken buckles can’t hold the straps in place, and any breaks or tears in the straps weaken the harness. Cracks in the facepiece lens, however, involve the eye/face protection of the respirator and its visibility, not the strap system. They’re a separate inspection concern from the head straps, so cracks in the facepiece lens are the item not related to head strap/harness inspection.
