ABSTRACT:
A fire extinguisher of compact, self-contained character is installed in electrical equipment by being mounted within an aperture of a housing for the equipment. The extinguisher has an elongated vessel for containing under pressure a fire extinguishing substance such as halogenated hydrocarbon type. A nozzle is carried at one end of the vessel and is closed by fusible material which melts at a predetermined temperature to permit discharge into the housing. The nozzle is formed as part of a fitting which carries a washer-like disc having an adhesive substance on it to permit adhesive securement of the extinguisher to the equipment housing, with the greatest portion of the vessel extending exteriorly of the housing and only a small portion of the extinguisher thus extending interiorly of the housing. The vessel has a relatively high aspect ratio, such as permitting it to be installed in an aperture defined by an electrical knock-out. The arrangement permits instalation in receptacle boxes, breaker boxes and various domestic and comercial electrical equipment.
