Tests were conducted in the experimental fire tower at the National Research Council of Canada to study smoke movement through elevator shafts caused by a large fire and to determine the effectiveness of mechanical pressurization in keeping the elevator shaft and lobbies tenable for evacuation of the handicapped and for use by firefighterso The tests indicated that pressure control is required to cope with loss of pressurization due to open doors° Equations were developed to assist in designing pressure control systems involving either a variable supply air rate with feedback control or relief dampers in the walls of the elevator shaft or lobbies. Tests conducted in the tower indicated that for both methods of pressure control, comparison of measured and calculated values of supply air rates and pressure differences are in good agreement.
