Nomex is a trademarked term for an inherently flame-resistant fabric with meta-aramid chemistry widely used for industrial applications and fire protection equipment. It was developed in the early 1960s by DuPont and first marketed in 1967.
Anti-flash gear, also known simply as flash gear, is basic personal protective equipment consisting of a fire-resistant hood and fire-resistant gloves, [1] nowadays often made of Nomex. Anti-flash gear protects to the head, neck, face and hands from short-duration flame exposure and heat.
A fog nozzle. A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets.By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its oxygen.
Besides meta-aramids like Nomex, other variations belong to the aramid fiber range. These are mainly of the copolyamide type, best known under the brand name Technora, as developed by Teijin and introduced in 1976. The manufacturing process of Technora reacts PPD and 3,4'-diaminodiphenylether (3,4'-ODA) with terephthaloyl chloride (TCl). [13]
Fire proximity suits first appeared during the 1930s, and were originally made of asbestos fabric. Today they are manufactured from vacuum-deposited aluminized materials that reflect the high radiant loads produced by the fire. An early manufacturer of the aluminized suits was the Bristol Uniforms company under the direction of Patrick Seager Hill.
In 1966, Simpson met NASA astronaut Pete Conrad, who introduced Simpson to the Nomex material used in spacesuits for the Apollo program. [25] [14] Around the same time, DuPont also approached the Hinchman company about producing Nomex racing suits. [30] [35] In that year's Indianapolis 500, driver Mel Kenyon wore a Nomex fire suit produced by ...
