BS EN 12101-3:2015EN 12101-3:2015 (E) 8 Introduction Smoke and heat control ventilation systems create a smoke free layer above the floor by removing smoke and thus improve the conditions for the safe escape and/or res
45、cue of people and animals and the protection of property and permit the fire to be fought while still in its early stages. They also exhaust hot gases released by a fire in the developing stage. In specific cases some fans are used to convey smoke (e.g. in tunnels or car parks). These fans, called j
46、et fans or impulse fans are also within the scope of this standard. The use of smoke and heat control ventilation systems to create smoke free areas beneath a buoyant smoke layer has become widespread. Their value in assisting in the evacuation of people from construction works, reducing fire damage
47、 and financial loss by preventing smoke logging, facilitating fire fighting, reducing roof temperatures and retarding the lateral spread of fire is firmly established. For these benefits to be obtained it is essential that smoke and heat control ventilators operate fully and reliably whenever called
48、 upon to do so during their installed life. A heat and smoke control ventilation system is a scheme of safety equipment intended to perform a positive role in a fire emergency. Components for smoke and heat control systems should be installed as part of a properly designed smoke and heat control sys
49、tem. Smoke and heat control ventilation systems help to: keep the escape and access routes free from smoke; facilitate fire fighting operations by creating a smoke free layer; delay and/or prevent flashover and thus full development of the fire; protect equipment and furnishings; reduce thermal effects on structural components during a fire; reduce damage caused by thermal decomposition products and hot gases. Depending on the design of the system and the ventilator, powered or natural smoke and heat ventilators can be used
