AbstractThis paper presents the results of tests conducted on the pressurized stair shafts of two buildings to asses the effectiveness of this method in maintaining stair shafts tenable in the event of fire. The effect of having some stair doors open was checked as well as the differences that occur when air is injected at the top or bottom of the shaft. The paper recommends injection of air at several levels to assure uniform shaft pressurization and substantial flow of air for dilution throughout the stair shaft. The data on the airtightness of stair-shaft walls and doors and on the resistance to flow within the stair shaft are also reported.
