CASE 2: Vertical Acting with Complying Swing Egress Door(s) and Side Acting Accordion with Complying Swing Egress Door

Elevator Separation

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 case study includes both a side acting accordion with conventional egress for the elevator lobby separation and a vertical acting with conventional egress acting as a smoke barrier opening protective in the corridor.
