Abstract	Nonfire and fire tests were conducted in the 10-story experimental fire tower to evaluate the performance of the mechanical smoke exhaust system, zoned smoke control system, and pressurized building method of smoke control. All three systems have something in common - mechanical exhaust of the fire floor. Tests with fire temperature of 450 degrees C and 650 degrees C indicated that the tower was kept smoke free outside the fire compartment with each system when all stair doors were closed. However, when one or two stair doors were open, including the one on the fire floor, smoke contamination of the stairshaft occurred for all three systems. For the mechanical smoke exhaust system, the entire tower was contaiminated when two stair doors were opened. For the zoned smoke control system, only the stairshaft was contaiminated, and, for the pressurized building method, the stairshaft and the floor space of the floor above the fire was contaminated. When another stair door was opened, the zoned smoke control system, whereas the contamination pattern remained unchanged for the pressurized building method of smoke control.
