A fire protection and/or extinguishing article comprises a sheet which has, uniformly dispersed therein, a material which undergoes an endothermic reaction to release a non-flammable gas and simultaneously absorb heat when subjected to an elevated temperature. This sheet is sandwiched between a gas permeable thermal barrier and a layer of gas permeable thermal insulation in a preferred embodiment which may function as a foldable and storable blanket.

A fire protection article comprising: an extinguishing/coolant agent, said agent comprising a dry material which is stable at room temperature and which will undergo an endothermic reaction to generate a non-toxic and non-flammable gas while simultaneously absorbing heat when subjected to an elevate

A fire protection article comprising: an extinguishing/coolant agent, said agent comprising a dry material which is stable at room temperature and which will undergo an endothermic reaction to generate a non-toxic and non-flammable gas while simultaneously absorbing heat when subjected to an elevated temperature, said extinguishing/coolant agent being selected from the group consisting of sodium bicarbonate, potassium bicarbonate, borax, monoammonium phosphate and urea potassium bicarbonate; a non-flammable and non-toxic adhesive, said adhesive and agent being intimately mixed and cured to define a non-porous layer having the agent uniformily dispersed therein, said adhesive being selected from the group consisting of neoprene elastomer, latex modified elastomer emulsions, synthetic elastomers and polyvinyl alcohol; and a thermal barrier layer, said barrier layer being comprised of a gas permeable fabric and being at least partly bonded to a first surface of said non-porous layer, said fabric being non-flammable and retaining its dimensional stability at temperatures above the temperature at which said agent undergoes an endothermic reaction, said fabric being comprised of fibers selected from the group consisting of glass, graphite and ceramic.
