AbstractA sprinkler-system controls the amount of smoke generated by fire as well as its spread, and should therefore be considered as a smoke control measure. Separate smoke control systems are often, however, included in the fire safety systems of sprinklered contemporary buildings to handle the smoke generated prior to activation of the sprinkler heads and subsequently from the sprinklered fire. A sprinkler system can also reduce the probability of window breakages by controlling fire temperature. If, as a result, it can be assumed that the exterior walls of the fire floor will remain intact, a smoke shaft with an exhaust fan at the top can ensure effective smoke control. The results reported are of tests conducted on a smoke control system of this type for a 34-story office building equipped with a light hazard sprinkler system.
