Workers who work in areas where there are electrical hazards are recommended to wear arc flash and flame-resistant coveralls at all times. Wearing a coverall is like wearing a single piece of clothing over your own clothing or under flame-resistant clothing worn as a base layer. Rather than putting on separate shirts and pants, they cover the worker's front, back, arms, and legs continuously, preventing sparks and spatter from entering the worker's waistline. For use near electrical equipment with arc flash hazards, arc flash protective garments must meet the NFPA 70E standards for use near electrical equipment. A flame-resistant and arc flash-resistant material is a self-extinguishing material that does not burn, melt, or cause a fire to occur. It should be noted that flame-resistant clothing is not necessarily arc flash-rated, and arc flash-rated clothing is not necessarily flame-resistant clothing. The wearing of different types of clothing at the same time is common in order to provide a greater level of coverage.
