Abstract
A foam concentrate or fire fighting composition for extinguishing and/or retarding fires is provided that meets UL162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents. The concentrate is used to form the fire fighting composition when mixed with water. The concentrate or fire fighting composition includes a high molecular weight fluoropolymer and water and may have a fluorine content wherein less than about 0.008% fluorine by weight of the fire fighting composition is provided from any fluorochemical surfactant. Further, the composition may meet the UL162, Class B performance criteria without forming a stable seal on cyclohexane.
Claims33
A foam concentrate comprising water and a high molecular weight fluoropolymer, the foam concentrate providing a fire fighting composition when mixed with water so that the fire fighting composition does not form a stable seal on cyclohexane and meets UL 162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents.
A foam concentrate for use in a fire fighting composition, the concentrate comprising water and a high molecular weight fluoropolymer, the foam concentrate providing a fire fighting composition when mixed with water so that the fire fighting composition does not form a stable seal on cyclohexane and meets UL 162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents, and wherein the concentrate has a fluorine content provided from any fluorochemical surfactant that provides the fire fighting composition with less than about 0.008% fluorine by weight of the fire fighting composition.
A foam concentrate for use in a fire fighting composition, the concentrate comprising water and a high molecular weight fluoropolymer, the foam concentrate providing a fire fighting composition when mixed with water so that the fire fighting composition meets UL 162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents, and wherein the concentrate has a fluorine content provided from any fluorochemical surfactant that provides the fire fighting composition with less than about 0.008% fluorine by weight of the fire fighting composition.
A fire fighting composition comprising water and a high molecular weight fluoropolymer, and wherein the composition does not form a stable seal on cyclohexane and meets UL 162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents.
A method of extinguishing or retarding a fire comprising:
- providing a fire fighting composition comprising water and a high molecular fluoropolymer that does not form a stable seal on cyclohexane and that meets UL 162, Class B performance criteria for at least one of AFFF agents, AR-AFFF agents and fluoroprotein (FP) agents;
- and
- applying the composition to an area where extinguishment or retardation of the fire is desired.
The method of claim 33, further comprising:
- applying the composition to the area in combination with a dry fire fighting agent.
