  • Fire extinguisher and fire extinguishing composition
    Patent number: 4226728
    Abstract: An improved fire extinguishing composition is described using two differing fire extinguishing fluids with or without the use of a nonfluorocarbon propellant. The two fire extinguishing fluids are a low vapor pressure halogenated alkane such as bromochlorodifluoromethane and a higher vapor pressure halogenated alkane such as bromotrichloromethane. The fire extinguishing composition is self propelled. Minor proportions of a propellant such as propane or carbon dioxide may be combined with the extinguishing composition for dispensing from an aerosol-type container.
