Risk calculators and risk factors for Silicosis risk factors |
- Main occupations that involve silicosis:
- Excavations in mines, tunnels, quarries, underground galleries
- Quarrying, cutting and polishing siliceous rock
- Dry cutting, grinding, sieving and manipulation of minerals and rock
- Manufacture of silicon carbide, glass, porcelain, earthenware and other ceramic products
- Manufacture and maintenance of abrasives and detergent powders
- Foundry work: cast shakeout, sprue removal and blast cleaning
- Milling work: polishing, filing products containing free silica
- Sandblasting and grinding
- Pottery industry
- Handling quartz conglomerates and ornamental stone
- Dental prostheses
A few cases of non-occupational silicosis have been reported in the ommunities living close to industries like quarries and sand works.
- Intensity of Exposure The risk of developing silicosis is closely linked to the accumulated exposure of an individual to crystalline silica during their working lifetime. Exposure can be calculated as follows:
- Accumulated silica dose = fraction of respirable dust × percentage of free silica in mg/m3 × number of years of exposure.[1]
