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 conduit, a cup-shaped retainer spaced from the outside surface of the conduit section so as to define an annular space therebetween, the annular space containing a suitable and pre-measured quantity of intumescent material, and a floating floor below the intumescent material which, in the event of fire, will move inwardly to occupy the interior space previously occupied by the conduit section.
