Arc flash and flame-resistant lab coats are worn over personal clothing to protect workers from burns and arc flash when working with flammable and combustible chemicals. Lab coats have a front closure and pockets. 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.
