Why should you use BS EN 12101-2- Natural smoke and heat exhaust ventilators in smoke and heat control systems?
In a fire situation, smoke and heat exhaust ventilation systems create and maintain a smoke-free layer above the floor by removing smoke. They also serve simultaneously to exhaust hot gases released by a fire in the developing stages.
The use of BS EN 12101-2 is to create smoke-free areas beneath a buoyant layer has become widespread. Their value in assisting in the evacuation of people from buildings and other construction works, reducing fire damage and financial loss by preventing smoke damage, facilitating access for firefighting by improving visibility, reducing roof temperatures, and retarding the lateral spread of fire is firmly established. For these benefits to be obtained it is essential that natural smoke and heat exhaust ventilators operate fully and reliably whenever called upon to do so during their installed life.
In BS EN 12101-2, a smoke and heat exhaust ventilation system is a system of safety equipment intended to perform a positive role in a fire emergency.
What’s changed since the last update?
