Which item is used to protect against arc burns?

• A. Fire-resistant clothing
• B. Rubber sheeting
• C. Insulating blankets
• D. Safety shoes

Answer: (A)

Arc burns come from arc flash, a sudden release of heat that can injure exposed skin. The best protection against this risk is flame‑resistant, arc‑rated clothing. Fire-resistant clothing is designed not to ignite or to self‑extinguish when exposed to intense heat, and it limits how much heat reaches the skin, reducing burn severity if an arc occurs.

Rubber sheeting isn’t worn on the body and isn’t designed to handle the high heat of an arc; it could melt and offer little real protection. Insulating blankets are used to cover or insulate equipment, not to protect a worker’s skin from arc heat. Safety shoes protect feet from shocks and some physical hazards, but they don’t shield the larger portions of the body from arc heat.
