RWA, Ventilations
We all know that in everyday life fresh air is important in order to be able to concentrate and remain fatigue-free when working and for general well-being. In the event of a fire, however, fast detection and removal of smoke is essential for survival. Find out how controlled ventilation can be implemented and how you can ensure that fresh air is supplied and smoke extracted where it counts.
Smoke-free escape and rescue routes
Toxic fumes must be removed from the building as quickly as possible. Smoke extractors are installed to provide natural smoke extraction. These systems can be activated automatically (via smoke detectors) or manually (via RWA buttons). They open ventilation slots such as windows or skylights.
These draw fumes and heat energy away from the building. Escape routes remain smoke-free and fire-fighters are able to intervene quickly, precisely where they are needed.
Smoke extraction needs fresh air
Smoke and heat extraction systems are dependent on smoke being extracted from above a supply of fresh air from below. This fresh air supports fire-fighting measures by:
- increasing thermal drive, resulting in fumes being drawn more quickly through windows or openings in the roof (chimney effect),
- creating a low-smoke layer along the bottom part of the room to provide a clear view of escape and rescue routes,
- reducing the amount of fumes and explosive smouldering gases as a result of cleaner combustion,
- reducing the heat, enabling fire-fighters to get closer to the fire.
