1. A fire extinguishing blanket for smothering a grease fire and absorbing the burning grease which is the cause of the fire, comprising:

  • an inner layer including a textile sorbent material which will absorb grease and oil, said material having a melting point greater than about 320°

    C. so that it does not melt at the temperature of the grease fire, anda fire resistant, porous outer layer disposed about the inner layer, said outer layer being of a material which will not ignite or melt at the temperature of a grease fire and being sufficiently porous to permit grease to penetrate through to said inner layer where it is absorbed,wherein when said blanket is positioned over a burning grease fire to cover the fire, said grease penetrates through said outer layer and is absorbed by said inner layer thereby depriving the fire of its fuel, and said outer layer forms an oxygen-excluding barrier which smothers the burning fire.
