Fire-extinguishing waste receptacle

Abstract

A waste receptacle comprises an upwardly open fire-resistant vessel having an upper rim, an annular head piece fittable over the rim and forming an upwardly open waste-passing mouth, a container mounted on the rim and holding a pressurized substance which when released at ambient pressure forms a gas that does not support combustion and that is heavier than air, a heat-conducting nozzle carried on the rim, connected to the container, and opening into the vessel, and a plug of fusible material blocking the nozzle and having a relatively low melting point. The container may be a halon- or CO.sub.2 -containing bottle and the melting point of the nozzle plug is about 70.degree. C. The head piece is easily separable from the vessel for emptying of same, and can be opened up to replace the gas-containing bottles and nozzles.
