Nomex does not burn like a cotton fabric and will not drip like polyesters, instead it expands while absorbing the heat energy to help prevent heat transfer to the worker exposed to fire or arc flash. A Nomex IIIA coverall and other garments give a worker time to escape allowing the garment to self-extinguish once the worker has been removed from the flame source. These protective qualities are why Nomex is used in a variety of different industries including but not limited to electricians, utility workers, the military, and those working in the oil and gas industry. Basically Nomex can be worn in any industry where there is need for protection from fire or electrical arc flash.
One of the most common garments worn across a variety of industries is Nomex Coveralls. Bulwark manufactures a Premium Nomex IIIA Coverall that is only 4.5 ounces.
