"FR coveralls are designed to protect workers/employees in most fire hazardous industries. Such hazards could include sparks and hot particles, molten metal splashes, electrical arc flash, flash fire, direct flame, radiant heat, solvents, acids, alkalis, oil and other hazardous substances. FR coveralls are designed to ensure that there are no gaps for sparks and molten splash to get through. Flame retardant boiler suits usually have other special features like studded cuffs and neck (to prevent ingress of sparks) and covered zips (the metal in the zip can otherwise get hot)."
