In the spring of 1989, a series of full scale fire experiments of zoned smoke control were conducted at the seven story Plaza Hotel in Washington, DC. A zoned smoke control system is a system that uses pressurization produced by fans to restrict smoke flow to the zone of fire origin. The benefit of these systems is that other5 zones in the building remain essentially "smoke free" reducing property loss and hazard to life. No zoned smoke control system has been tested under real fire conditions either by a research effort or an accidental fire. However, fire experiments of smoke control systems for stairwells and elevators have been conducted.
