Smoke ventilation allows the creation of a smoke free layer above the floor by removing smoke. This improves the conditions for safe escape and permits the fire to be fought in its early stages. The effects of smoke being generated by fire can reduce the visibility for the occupants and can increase the time to escape the fire, creating greater exposure to smoke inhalation that can consequently cause loss of consciousness. The systems are designed to create a smoke free layer above the floor by removing smoke from the building. This is achieved by using the natural buoyancy of the hot gases to rise and exhaust through automatic opening vents. This significantly improves the condition for safe escape by occupants and permits the fire to be fought in its early stages. Building owners, designers, developers and stakeholders share a responsibility to reduce the risk of fire. If a fire does occur the occupants must be protected. The installation of a smoke and heat control system can limit the potentially tragic effects of a fire by significantly increasing the conditions for safe escape and by permitting the fire to be fought in its early stages.
