Arc flash and flame-resistant coveralls protect workers from arc flash burns that can occur when working near electrical hazards. Coveralls are a single garment worn over personal clothing or base-layer flame-resistant clothing. They provide continuous coverage over the worker's front, back, arms, and legs to prevent sparks and spatter from entering at the waist as can happen when wearing a separate shirt and pant. Arc flash protective garments meet NFPA 70E standards for use near electrical equipment where arc flash hazards exist. Arc flash and flame-resistant material resists burning and melting and is self-extinguishing. All arc flash clothing is flame-resistant but not all flame-resistant clothing is arc flash-rated. Different garment types are often worn together to provide more coverage.
