Abstract

Measurements made on two buildings reveal that leaky wall construction of a smoke shaft can seriously affect the performance of a smoke control system. Also revealed is that a stairshaft can be contaminated with smoke, particularly in summer when the stair door on the fire floor and the exit door of the same stairshaft are opened at the same time.
