ABSTRACT:
A fire, heat and backdraft protection system is described for protecting firefighters in all types of fires. The protection system includes a composite laminate structure having a plurality of layers for the protection of firefighters who are exposed to high temperatures of 2200.degree. F. for 30 minutes in duration. The plurality of layers includes an outer first layer, an inner second layer and an inner third layer. The outer first layer is a fiberglass textile having an intumescent coating resistant to heat, water and impact. The inner second layer is a metal foil layer for reflecting heat and eliminates the convection transfer of heat. The inner third layer is a low conductivity refractory blanket for reducing the transmission of heat. The inner fourth layer is a metal foil layer for reflecting heat and eliminates the convection transfer of heat.
