Tenability analysis along with computational fluid dynamics (CFD) are recognized methods of atrium smoke control analysis by NFPA 92, Standard for Smoke Control Systems. Tenability analysis evaluates the following threats to life: toxic gas exposure, heat exposure, thermal radiation exposure, and reduced visibility. In dense smoke, people see poorly and often become disoriented which prolongs exposure time of the other threats. Also falls from balconies can result from reduced visibility. This paper discusses these threats as they apply to atria smoke control and how tenability analysis can be incorporated in CFD simulations of atrium smoke control systems.
