Fire suppression compositions and methods of treating subterranean fires

摘要

A method of suppressing, reducing and/or extinguishing a subterranean fire comprising contacting the subterranean fire with a fire-suppression composition comprising a carrier agent and a flame-retardant salt. A method of treating a peat fire comprising locating one or more hot spots associated with the peat fire, preparing an aqueous solution of a fire-suppression composition comprising guar and monoammonium phosphate, wherein a ratio of guar to monoammonium phosphate is about 30:70; and contacting the peat fire with the aqueous solution.

1. A method of suppressing, reducing and/or extinguishing a subterranean fire comprising contacting the subterranean fire with a fire-suppression composition comprising a carrier agent and a flame-retardant salt wherein the method of suppressing, reducing, and/or extinguishing the subterranean fire excludes the formation of one or more access sites via excavating, drilling, or digging to form a conduit from the surface of the earth to a fuel source of the subterranean fire; wherein the subterranean fire comprises a peat fire, a muck fire , a coal seam fire, or a landfill fire and wherein the subterranean fire is disposed from about 1 to about 15 feet below the surface of the earth.
