Smoke Ventilation Systems
Residential properties and other properties deemed by the risk assessment are required to be able to ventilate the products of combustion away to allow the safe escape of building occupants and access to the fire and rescue services.
The most common use of smoke ventilation is within the common parts of residential dwellings where the evacuation policy is a stay put policy i.e. where only the occupants within the flat of fire are required to evacuate.
