On call and at the ready 24 hours a day. Firefighters and emergency personnel around the world rely on turnout gear, EMS wear, station wear, and accessories made with DuPont fibers. At DuPont, we know superior thermal protection is your top priority. Unlike other materials and fibers available to firefighters and emergency service personnel, products made from DuPont NOMEX® fibers are inherently flame-resistant and won’t melt, drip, or support combustion in the air. And the thermal protection offered is permanent — its superior flame resistance cannot be washed out or worn away.
