Abstract:
1. A safety apparatus for inhibiting an outbreak of an electrical fire within an electrical box, said apparatus comprising: a heat sensitive device disposed within the electrical box for sensing a potentially hazardous temperature rise within the electrical box caused by an electrical fault in the electrical box; said heat sensitive device includes: a bimetallic strip which warps in response to said potentially hazardous temperature rise within the electrical box; a control device associated with said heat sensitive device such that said control device is activated by said heat sensitive device when said heat sensitive device senses said potentially hazardous temperature rise within the electrical box; an electrical fire inhibiting device operably connected to said control device, said electrical fire inhibiting device having a dormant mode and a fire extinguishing mode such that when said control device is activated by said heat sensitive device, said control device switches said fire inhibiting device from said dormant mode to said fire extinguishing mode so that the outbreak of the electrical fire within the electrical box is prevented; said electrical fire inhibiting device including: a canister which defines an enclosure and a neck portion; said enclosure containing a vaporous propellant, liquid propellant and foaming agent; and a mixing valve disposed within said neck portion such that when said fire inhibiting device is disposed in said fire extinguishing mode, said vaporous propellant, liquid propellant and foaming agent are mixed by said mixing valve so that said mixed vaporous propellant, liquid propellant and foaming agent flow through said neck portion and past said mixing valve for extinguishing the electrical fire.
