CASE 4: Vertical Acting with Multiple Complying Swing Egress Doors
Hoistway protection is designed to isolate fire, smoke, heat and toxic gases or fumes from migrating floor to floor through vertical hoistways in multi-story structures. There are two fundamental methods prescribed in this code section, elevator lobbies or protection at the point of access to the elevator car.
This project introduces the use of fire protective curtain assemblies that have been approved in accordance with the current editions of the model buildings codes (see IBC Section 3006.3, Item #2. Specific reference to this technology is now approved as opening protectives without hose stream performance [UL 10D 20-minute fire rated] for publication in the 2021 edition of the IBC [See Appendix, Resource IBC 2021]).
