Effective Smoke Control with a Pressurisation System

Smoke control is often talked about when the topic of fire is being discussed – but what does this actually mean? Smoke control is the term used to describe a system that is put in place which creates an area which does not contain any smoke or other toxic gases.
Smoke ventilation is the traditional method used as smoke control. Smoke ventilation refers to the extraction of smoke from a certain space. Smoke ventilation has widely been used to clear smoke from car parks, shopping centres, etc. However, when it comes to multi-storey office and residential buildings, smoke ventilation can, in fact, make the situation much, much worse.

The alternative smoke control system to smoke ventilation is smoke pressurisation. Smoke pressurisation is the method of preventing smoke and toxic gases from entering a designated area in the first place. This smoke-free area can then be used as an escape route for all individuals occupying the building. Areas which use smoke control systems also provide access for fire fighters who need to get into the building to assist anyone who is unable to get out. Smoke pressurisation works by supplying a clean supply of air into the escape routes and, therefore, developing excess or positive pressure in the designated spaces.
