Abstract

Abstract This invention is directed to a non-toxic fire extinguishant. More particularly, this invention relates to a fire extinguishant which extinguishes fires without generating toxic gases or compounds. A non-toxic fire extinguishant comprising in combination: (a) A fluorochlorocarbon selected from the group consisting of trichlorofluoromethane, dichlorodifluoromethane, 1,2-dichlorotetrafluoroethane, chlorodifluoromethane, 1,1-dichloro-2,2,2-trifluoroethane, 1-chloro-1,2,2,2-tetrafluoroethane, pentafluoroethane, 1,2-dichloro-2,2-difluoroethane, 1,2,2,2-tetrafluoroethane and (b) a substance selected from the group consisting of Terpenes: Citral, Citronellal, Citronellol, Limonene, Dipentene, Menthol, Terpinene, Terpinolene, Sylvestrene, Sabinene, Menthadiene, Zingiberene, Ocimene, Myrcene, α-Pinene, β-Pinene, Turpentine, Camphor, Phytol, Vitamin A, Abietic Acid, Squalene, Lanosterol, Saponin, Oleanolic Acid, Lycopene, β-Carotene, Lutein, α-Terpineol, p-Cymeme; and unsaturated oils: Oleic Acid, Linoleic Acid, Linolenic Acid, Eleostearic Acid, Lincanic Acid, Ricinoleic Acid, Palmitoleic Acid, Petroselenic Acid, Vaccenic Acid, Erucic Acid.
