It is imperative for the exit stairs to be free of smoke and to incorporate design Stair pressurization. Due to the relative cost of the associated mechanical systems, and architectural space issues related to providing exterior balconies and stair NFPA 92B – Guide for Smoke Management in Malls, Atria, and Large Areas.

A. This section includes the design and control requirements for stairwell pressurization systems. B. Refer to A. The stairwell pressurization system will have a minimum of one fan per stairwell. Provide an isolation Each stairwell fan will also be individually controlled, through the BFAS, by a manual local on-off switch on

20 May 2016 The 2015 IBC also contains additional design criteria for these system types. Note that the codes do not always require compliance with NFPA 92 whenever a smoke control system is required. For example, for smokeproof enclosures (e.g., pressurized stairs and elevator hoistways), the IBC has
