NO-94-12-1 -- Fire Tower Tests on Vestibule Pressurization for Protection of Stairshafts PDF

Describes a series of tests in a 10-storey experimental fire tower on various types of stair pressurisation systems for providing tenable escape routes during a fire, conducted by the National Research Council of Canada as a joint research project with ASHRAE. In addition tests were conducted to investigate the performance of a) a stair vestibule pressurisation system alone, b) a stair vestibule pressurisation system in combination with stairshaft pressurisation and c) a stair vestibule pressurisation system in combination with mechanical exhaust of the fire floor. Provides the test results and the conclusions.
