- Abstract
- Smoke is recognized as the major killer in fire situations. In the late 1960's, the idea of using pressurization to prevent smoke infiltration of stairwells started to attract attention. This was followed by the idea of the "pressure sandwich"--venting or exhausting the fire floor and pressurizing the surrounding floors. Frequently, the building's ventilation system is used for this purpose. The term "smoke control" was coined as a name for such systems that use pressurization produced by mechanical fans to limit smoke movement in fire situations.
