What type of system is used to control levels of smoke in a building during a fire?

The smoke control system is specifically designed to manage smoke movement within a building during a fire event. Its primary function is to limit the spread of smoke, which can be incredibly harmful to occupants and can inhibit evacuation and fire-fighting efforts. This system typically employs a combination of mechanical and passive measures, such as fans and dampers, to direct smoke to designated areas, remove it from escape paths, and maintain tenable conditions in certain zones of the building.

Unlike alarm systems, which focus on alerting occupants and authorities to the presence of smoke or fire, and sprinkler systems, which are designed to suppress flames by discharging water, the smoke control system is primarily concerned with managing smoke. While general ventilation systems can assist in smoke management by introducing fresh air and exhausting smoke, they are not explicitly designed for this purpose. A smoke control system integrates various strategies to enhance safety during a fire, ensuring that areas can remain accessible and that smoke does not hinder rescue operations.
