ABSTRACT:
A barrier assembly for blocking the spread of fire and smoke includes a building partition having a partition outer face and having a substantially circular partition opening, the partition opening having a certain opening inner diameter, a plastic pipe having a pipe outer diameter and passing through the partition opening, a tube having a tube outer diameter sized to fit snugly through the partition opening and having a tube inner diameter larger than the outer diameter of the pipe so that there is a substantially annular space between the pipe and the tube, flange means extending from a first end of the tube to abut the partition outer face around the opening, a substantially annular gasket fit into the tube for receiving the pipe acting as a smoke barrier around the pipe, the annular gasket having a gasket inner diameter substantially larger than the pipe outer diameter to permit non-concentric positioning of the pipe within the annular gasket during barrier installation and during pipe adjustment and replacement, and ring of intumescent material located within the substantially annular space between the tube and the pipe for acting as a fire barrier by expanding to close the partition opening and thereby block the passage of fire when fire melts the plastic pipe, the ring of intumescent material having an intumescent material ring inner diameter substantially larger than the pipe outer diameter.
