NOMEX® flame resistant coveralls from Bulwark® are used by professionals in high risk occupations such as the Petrochemical industry, and by fire fighters, auto racers, military, and utilities personnel. Pictured here: Deluxe Coverall HRC2 (Product ID CEB2).

NOMEX® coveralls are made from flame resistant 9 oz. 100% cotton twill. They have an arc rating of ATPV 11.2 calories/cm2, meaning they can protect the wearer from an arc flash or arcing faults that pass through normal fabrics. The term HRC2 indicates the risk level of the occupations that typically use this coverall.

The Nomex coverall’s flame resistant property does not degrade, even after multiple washings. The coveralls’ fibers are unaffected by bleaches, solvents, and most acids (as long as it is not exposed for a long time to these chemicals) and generally has good resistance to alkalis. However, the fabric does not provide personal chemical protection to the wearer. Where chemical exposure is a hazard, appropriate specialized barrier garments should be selected.

NOMEX® is highly flame resistant and does not melt. The fiber decomposes between 700°-800°F. Although it is fire resistant and arc resistant, the NOMEX® coverall HRC2 is not recommended for use around any molten substances, welding operations, or in a critical static control application. It is especially important that NOMEX® garments NOT be put on or removed in a hazardous area due to static electricity.

The Bulwark NOMEX® coverall costs about five times as much as conventional 65% polyester/35% cottons, and about two times more than Flame Resistant cotton coveralls. But they also last 2-3 times longer than the conventional polyester cottons and 3-5 times longer than Flame Resistant cotton coveralls.
