Sprinklers systems are well known as one of the most efficiently suppression tool in building fires, however it is apprehended that sprinkler sprays might disturb the stratified smoke layer during initial stage of fire. On the other hand, mechanical smoke exhaust system also is used to delay the descent of the interface between upper and lower layers and to secure the evacuee’s safety in fire in the high-rise and large scale buildings. In this study, a series of full-scale experimental study was carried out to unveil the effect of the sprinkler sprays, the mechanical smoke exhaust system and the length of smoke curtain on the smoke layer height. As a result, the useful experimental data on their relation was reported for applying to a simulation model related to fire.
