Abstract
Fire flooding and extinguishing agents and detoxifiers which are environmentally safe and non-toxic in both natural form and in fire exposed degraded forms are disclosed. The flooding and streaming-type fire extinguishing agents are rich in low boiling, unsaturated halocarbon compounds having low liquid viscosities, and low boiling alkenes as detoxifying agents. The detoxifiers are conjugated double bond hydrocarbons.
Claims2
A halogenated fire extinguishing flooding mixture comprising:
- (a) about 90% to 99.9% wt. of one or more species of partially halogenated hydrocarbon fire extinguishant, said partially halogenated hydrocarbon fire extinguishant containing at least one hydrogen atom;
- and
- (b) about 0.1% to 10% wt. of a detoxifying agent comprised of 1,3-butadiene, said detoxifying agent reducing the amount of hydrogen halides and carbonyl halides that are produced on decomposition of the mixture due to exposure of the mixture to fire, said flooding mixture having a boiling point of between about -85.degree. C. to 25.degree. C.
A non-toxic environmentally benign fire extinguishing mixture for use in a flooding fire extinguishing technique, said fire extinguishing mixture comprising about 82% wt. HCFC-22, about 9.5% wt. HCFC-124, about 4.75% wt HCFC-123 and about 2% wt. 1,3-butadiene.
