Depending on the structure and building envelope, SE Controls can provide either a code compliant solution or a fire engineered solution, to facilitate safe occupant escape or good visibility for the fire service to enter the effected floor. With an extensive range of products to meet any smoke ventilation solution, SE Controls provide certified and compliant products to create a life saving system.
If the corridor extends to the external wall an AOV can be installed to remove smoke from the common corridor/lobby.
The prime objective of a smoke control strategy is to keep the escape stair free from smoke, by using the natural buoyancy of the hot gases to exhaust through AOVs.
It is not always viable to install a prescribed natural smoke shaft, in which case a mechanical smoke shaft would be CFD modeled and installed.
A natural smoke shaft utilises automatic opening smoke doors or dampers to draw smoke into the smoke shaft and out the affected area through a roof vent at the top of the shaft.
