ABSTRACT
This chapter tabulates the main design and operational conditions of the atrium smoke management system. It indicates the importance of smoke management system in case of atrium fires using exhaust to keep the tenability conditions required to ensure occupants’ safe evacuation. Increasing make-up air velocity above 1 m/s has adverse effect on smoke layer height and tenability conditions at the human level. The chapter places emphasis on car service centers where cars are parked waiting for service and maintenance. These service areas pose a range of fire risks from flammable liquids to high-tech equipment, plus a potentially combustible mix of dust, swarf, and lubricants. The ducted ventilation system depends on smoke extraction through ductwork connected to exhaust fans sized to offer an air change rate inside the car service area. Using smoke barriers with impulse ventilation have a great effect on improving the performance of the smoke management system.
