Fire Partitions – 716.5.42007 Damper Requirements

Smoke Dampers are required for all fire-resistance rated corridors. Table 1017.1 defines fire-resistance rating by occupancy.

All CSFM regulated buildings require 1-hour rated corridors.

707.14.1 Elevator Lobbies Smoke dampers requirements = corridor requirement.

CSFM Regulated Buildings Fire & Smoke DampersFire & Smoke Dampers Group A, E, H, I, L, & R, High-Rise buildings, & others per Section 111.

EXCEPTION: Openings in steel ducts limited to a single smoke compartment.

Smoke Barriers – 716.5.5 2007 Damper Requirements

Note: Fire damper requirements are not clearly spelled out, but it’s a safe bet that they should be included given the 1-hour fire resistance rating of all smoke barriers.

Smoke Partition – 710.72007 Damper Requirements

Smoke partitions are typically not fire-resistance rated and are constructed to limit the transfer of smoke.

Locations: Elevator Lobby Alternative (707.14.1)
