Flame resistant coveralls are required for many industries where flash fire and electric arc flash hazards are or may be present, including the oil and gas industry. There are two types of FR coveralls available – inherently FR and treated FR. Coveralls that are inherently FR, like Nomex, are made flame-resistant for life, which means that no matter how many times they are laundered or how long they are worn, the material will always remain flame-resistant. Treated FR fabrics have a chemical applied to them that makes them flame resistant; however, normal wear, laundering, abrasion, and UV exposure gradually reduces the protective value of the garment over time.
