ABSTRACT:
An improved chimney-fire safety device includes a cylindrical canister that is placed in the top of a chimney or a stovepipe. The canister contains a mesh basket which has one or more membranes that are filled with extinguishing compounds. The mesh basket and a protective insulation platform are retained in the canister during controllable fires. The basket is secured to the canister by a tether. A fuse cap located in a bottom portion of the canister retains the basket, but disintegrates at a temperature commensurate with that of a runaway fire. When the fuse cap disintegrates, the mesh basket containing the extinguishing compounds drops from the canister and becomes suspended over the fire due to the tether; thus, the extinguishing chemicals are dispersed to the fire in a controlled fashion.
