Dust - Industrial dust may come from the grinding, crushing, cutting, or drilling metals, stone, or coal. There are two divisions of industrial dust...organic and inorganic.
Organic dusts come from substances whose source is plant or animal life, such as coal, leather, flour, sugar, feathers and cotton. They may produce allergies, skin irritations, or asthma. Miners of both soft and hard coal may develop a disabling shortness of breath because of the effects of coal dust on their lungs.
Inorganic dusts come mainly from metals and minerals. The most dangerous inorganic dust is silica, which causes silicosis. Asbestos dust also causes and inflammation of the lungs, called asbestosis. Workers exposed to dangerous dusts should be protected by the use of exhaust systems or suction devices that catch the dust at its place origin. Below are some of the safety tools for work hazards.
