Fire Rated Chemical Seal for Pipe/duct Penetrations Through Structural Slabs

This fire rated chemical seal is intended to prevent chemical leaks through structural slabs due to standing liquid spills or equipment malfunctions.

Referring to the figure, a pourable, self leveling epoxy grout forming a dam 1, a pourable polysulfide rubber chemical seal 2, and a fiber staffing insulation seal 3 surrounds floor penetrations that accommodate piping. A seal composed of cement 4 is applied in order to stop particle migration due to building vibration.
