Fire Protection Gas Suppression System or simply called as Automatic Fire Suppression System (or Gas Suppression System), is relatively a new technology in India. Unlike conventional system that use water, in Gas Based Fire Suppression System; water is never used and yet the fire is extinguished. Here Gas is used to extinguish the fire. Hence it is a Gas Based system. The fire gets extinguished, within a minute of activation and everything is automatic.
Fire Suppression Systems / Novec™ Novec™ 1230, manufactured by 3M™, is a unique fire extinguishing agent. Among the Clean Agents, it has the lowest atmospheric lifetime of 5 days. It is stored as a liquid, which makes it easier for transport, and also has a "zero ozone depletion potential"
FM200 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle (Oxygen, Heat and Fuel). The typical concentration of an FM200 system is normally between 7.9% to 8.5%
A fixed installation designed to displace the oxygen in the protected space and thus extinguish the fire, usually used to fight fires in engine rooms, boiler rooms, pump rooms and holds. The system normally consists of a series of large CO2 cylinders. The CO2 is supplied from the cylinder manifold to suitable points with diffusing nozzles. The discharge valve is located in a locked cabinet. Opening the cabinet activates an alarm to give personnel time for evacuation. Since the effectiveness of fixed CO2 firefighting system diminishes the longer the fire burns, the speed is essential if CO2 is to be effective.
An exhaust hood, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, doors, heat, and steam from the air by evacuation of the air and filtration. In commercial kitchens exhaust hoods are often used in combination with fire suppression devices so that fumes from a grease fire are properly vented and the fire is put out quickly. Commercial vent hoods may also be combined with a fresh air fan that draws in exterior air, circulating it with the cooking fumes, which is then drawn out by the hood.
