Which protective equipment helps reduce exposure to arc radiation?

• A. Leather gloves
• B. Welder's cap
• C. Shade or tinted face shield
• D. Steel-toed boots

Answer: (C)

Arc welding produces intense ultraviolet and infrared radiation that can burn skin and injure eyes. The best way to cut exposure is to have a filter that blocks most of that radiation while still letting you see the weld clearly. A shade or tinted face shield does exactly this: it reduces the harmful UV/IR and glare reaching your eyes and face, protecting you during the weld. Leather gloves protect the hands from heat and sparks, but they don’t reduce radiation reaching the eyes or face. A welder’s cap offers limited protection against sparks on the top of the head, not the radiation from the arc. Steel-toed boots guard the feet from falling objects or hot materials, not radiation exposure. So the shade or tinted face shield is the protective equipment that directly lowers arc radiation exposure.
