Fire stopping is best defined as the sealing of any openings to prevent fire (including smoke and heat) from passing through multiple building compartments.
To help prevent the rapid spread of fire within a building, certain walls and floors are required to meet a specific fire resistance rating (i.e., the period of time during which a building component has been tested to confine or compartmentalize a fire, or continue to perform a structural function).
Firestopping components include intumescents, cementitious mortars, silicone, firestop pillows, mineral fibers, and rubber compounds.
Joints between fire-separating elements such as compartment walls or floors, should be fire-stopped to maintain the continuity of resistance; and openings for timber beams, joists, purlins and rafters, and pipes, ducts, conduits or cables that pass through any part of a fire-separating element should be kept as few in number as possible, kept as small as practicable, and fire-stopped.
