ABSTRACT:
A fire safety device for closing through-holes in floors and walls and for thus stopping the potential spread of fire and smoke in case of the occurrence of a fire, includes a section of pipe having a weakened wall, a cup-shaped retainer spaced from the outside surface of the pipe section so as to define an annular space therebetween, the annular space in turn being provided with a suitable and pre-measured quantity of intumescent material. The device is pre-fabricated and thus avoids the problems inherent in attempting to manually provide the intumescent material in a collar during construction.
