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.
