Clothing for firefighters

Structural firelighter protective clothing is designed to protect firefighters from heat and other environmental hazards, such as abrasive objects and unpredicted chemical substances. The turnout gear (jacket and trousers only) typically consists of at least three functional layers, including an  

The MB is typically the middle layer between the OS and TL it is expected to prevent water, high temperature water vapour, chemicals and other pathogens from the environment passing through the firefighters clothing. It is usually a PTFE permeable film barrier laminated to a thin polyaramid woven or non-woven backing substrate. 

New materials and designs have been developed for heat protective clothing. For example, improved thermal insulation can be provided by non-wovens made with thin hollowed fibres, and can be made thermo-adaptive with two-way shape memory alloys such as nickel-titanium. Better thermoregulation inside the garment is sought with PCM, either encapsulated ° or incorporated in a matrix. Other solutions use external power, e.g., for liquid coolant circulation or with Peltier cells embedded in the textile.  

The OS is the outermost layer that provides both resistance to fire and prevents water ingress, cut, stab, tear and abrasion hazards which might be present at the fire scene. It might provide 25-30% of the total thermal protection

Nomex is another aramid fiber. Kevlar and Nomex differ only in that the substitution pattern in the aromatic rings is para in Kevlar but meta in Nomex. Nomex is best known for its fire-resistant properties and is used in protective clothing for firefighters, astronauts, and race-car drivers. 

U.S. market is about 20 million pounds per year. The applications are those where one needs very high flame resistance (clothing for firefighters and welders, welder s protective shield, upholstery and drapes), heat resistance (ironing board covers, insulation film for electrical motors and transformers, aerospace and military), dimensional stability (fire hose, V- and conveyor belts), or strength and modulus (circuit boards, bulletproof vests, fiber optic and power lines, ship mooring ropes, automobile tire cord, puncture-resistant bicycle tires).

Another use of antimony in household plastic includes its use as a flame retardant in PVC covers of crib/cot mattresses (Jenkins et al. 1998a, b McCaUum 2005). While antimony has been detected in children s toys made of PVC, it is not clear if its use was as a pigment in the actual PVC or in paints used on the surface of toys (Kawamura et al. 2006). Antimony is also used in synthetic fabrics as a flame retardant, including use in protective clothing for firefighters (de Perio et al. 2010).
