Description

There are primarily three contributors to start/sustain a fire. 1. FUEL 2. OPTIMUM TEMPERATURE 3. OXYGEN Firstly, to extinguish a fire, the fuel or burning material can be removed to douse a fire. Secondly, the temperature of surroundings or surfaces supporting the fire can be reduced. Lastly, the supply of oxygen can be blocked to extinguish a fire. This concept of Falling Roof is based on the third way to douse a fire, i.e. to block the supply of oxygen to stop the fire. Now why this scheme out of 3 ways is selected? The reason is the conditions defined in the design brief. The garment/clothing/textile factories will always have textile material which is combustible. So fuel for the fire is always available. Reducing the temperature to douse the fire will involve energy consumption (reduction in temperature involves energy dissipation). This energy is mostly bound to come from electrical supply, which mostly gets disturbed in case of fires. Thus this way to douse fire loses its reliability. Now cutting off the supply of oxygen can be easily achievable, as it just involves isolating the fire once and that's it. The FALLING ROOF device hangs over the workstations in a textile industry. As soon as there is afire in any workstation, the roof falls over it and isolates it from the surrounding air. The fire is choked and thus extinguishes due to lack of oxygen. The same system can be implemented on the warehouse where textiles are stored. So storage must happen in blocks, where small units of FALLING ROOFS can be installed.
