Which PPE item is a key component of arc flash protection?

• A. Flame-resistant clothing
• B. Cotton shirt
• C. Regular safety glasses
• D. Flip-flops

Answer: (A)

This tests understanding that flame-resistant clothing is a key part of arc flash protection. Arc flash can release extreme heat and radiant energy, so the first line of defense is clothing that resists ignition and self-extinguishes. Flame-resistant garments slow heat transfer to the skin and reduce burn severity, giving you time to react or escape. A cotton shirt can ignite and burn, potentially making injuries worse. Regular safety glasses protect eyes from debris but don’t shield you from the intense heat of an arc; you need arc-rated eye and face protection for the heat and radiant energy. Flip-flops offer no protection at all and are unsafe around energized equipment. So, flame-resistant clothing is the best choice for protecting against arc flash.
