Abstract

A battery housing has a body and a lid mateable with the body. The body and the lid, when mated, provide a chamber dimensioned to hold at least one battery; and a venting passageway from the chamber. At least a portion of at least one of the body and the lid comprises an intumescent flame retardant material with an expansion ratio sufficient to drive gas from the chamber through the venting passageway and to seal the chamber when the material intumesces in the event of thermal runaway of a battery housed in the chamber.

Abstract

A system for use with a ceiling fixture, a portion of which projects though an opening in a ceiling wall, for assisting in preventing spread of fire through the opening. The system has a metal collar for lining the opening. The metal collar has an upper rim overlying a top surface of the ceiling wall at the opening, a middle section facing an inner edge of the ceiling wall at the opening and a lower rim underlying a bottom surface of the ceiling wall at the opening. The system also has an intumescent ring for surrounding the projecting portion of the fixture so as to be interposed between the metal collar and the projecting portion of the fixture.

Abstract

An intumescent firestop element is supported within a light can by fire sensitive supports each having a base fabricated of a meltable or flammable material and a supporting element fabricated of metal and supported by the base, with the base joined to the light can. In response to a fire, the fire sensitive supports cease to support the firestop element which drops to a deployed position in the light can until arrested by a limiter.

Abstract

A cooling tower with a plurality of fill packs has a fire stop with openings disposed below the fill packs, a water distribution system for distributing water onto the fill packs, and a cold water basin disposed below the fire stop for collecting water which has past through said fill packs. The openings in the fire stop occupy at least 80% of the area over which the fire stop extends. The fire stop is made of an intumescent material with an expansion ratio sufficient to close said openings when said material intumesces.
