Description: Nortown Casitas, Toronto (North York), Ontario, Canada, April 1995: Plastic Pipe and Metal Pipe Penetrations being firestopped. The plumber had used all 4" diameter sheet metal cans to form the openings. The annuli for 2" and 3" piping were, therefore, oversized. Firestop Mortar was used to narrow the annuli. Intumescent collars were inverted inside the firestops. The intumescent wrap strips were made of 3M's FS195. The mortar was 3M Fire Barrier Mortar. The expanded FS195, in a fire, would choke off the melting plastic pipes. Metallic pipes were firestopped with firestop mortar.
