A worker who does not wear an arc- and flame-resistant coverall when they are working near an electrical hazard is at risk of getting arc flash burns. Coveralls are usually worn over flame-resistance clothing and personal clothing in order to provide protection from flames. The garments protect the worker's front, back, arms, and legs from sparks and spatter, as opposed to separate shirts and pants that are worn separately. When there's an arc flash risk near electrical equipment, arc flash protective garments need to meet NFPA 70E. Melting and burning aren't a problem for the self-extinguishing material. Clothing that is arc flash rated is always flame-resistant, but not all flame-resistant clothing is arc flash rated. In order to provide more coverage for the body, different types of garments are often worn together.
