Fire costs money. The cost as a consequence of fire, including property damage, human casualties and lost business, was estimated at £2.5 billion. If a fire does occur then occupants must be protected.
SE Controls offers a comprehensive range of natural and powered Smoke Heat and Exhaust Ventilation systems (SHEV) suitable for any size and type of building. Systems are designed to facilitate the safe escape of occupants in the event of a fire and to enable the fire to be fought in its early stages.
In residential buildings it is likely that a fire would occur within an occupant’s apartment. During the occupants escape, it is probable that smoke would enter the common corridor or lobby. The smoke control system is designed to ventilate this smoke and to protect the common stair, to ensure safe occupant escape and clear access for the fire service.
Smoke extraction can be achieved by using natural smoke ventilation in accordance with Approved Document B or where this is undesirable, through mechanical extract systems following a detailed fire engineered solution. Automatic Opening Vents (AOVs) on the external wall of the building or in a vertical smoke shaft can be used to ventilate smoke from common areas. In conjunction with both methods, an AOV at the top of the common escape stair needs to be operated simultaneously with AOVs in the affected area.
