There are two types of smoke ventilation systems and it is important not to confuse the two:
These are intended to provide a level of protection to people escaping the building. They are typically installed in shopping centres or malls, retail and private warehouses, public and industrial buildings and the like where due to the design of the buildings the escape routes to outside are complex or escape distances are greater then those recommended in the building regulations.
Such systems are designed so that the expected quantity of smoke is vented from the area leaving a layer of clean air below. Within this clear layer people are able to pass and exit the building safely. Smoke ventilation systems do not generally have any influence on the size of a fire in the building and they are therefore often used in conjunction with water sprinkler systems which can often contain the fire to a predetermined size.
