Dust is an undesirable by-product of many industrial processes. It settles everywhere: in machine rooms, on roof rafters and floors, in concealed spaces and remote areas. In high concentrations, airborne dust is not only an occupational health concern for workers inhaling it, but, with the high static electricity levels and other ignition sources found in manufacturing plants and mills, also represents an ever-present risk of fire and explosion.
The fire detection in a high concentration dust is a great challenge and can be achieved only with special fire detection techniques. The fire extinguishing is a combination of Gas based fire suppression system and sprinkler system.
