Overview

Occupational exposure is the most significant risk factor of silicosis. Excavations in mines, tunnels, quarries, and underground galleries, quarrying, cutting and polishing siliceous rock, and manufacturing of silicon-based products are all associated with increased risk of developing silicosis.

Risk Factors

The risk of developing silicosis is associated with the cumulative exposure of an individual to crystalline silica.

  • Accumulated silica dose = Fraction of respirable dust × % of free silica in mg/m3 × Number of years of exposure[1]

Occupational exposure is the most significant risk factor of silicosis. The most common occupations that involve exposure to silicosis are shown below:

  • Excavations in mines, tunnels, quarries, underground galleries
  • Quarrying, cutting and polishing siliceous rock
  • Dry cutting, grinding, sieving and manipulation of minerals and rock
  • Manufacturing of silicon carbide, glass, porcelain, earthenware and other ceramic products
  • Manufacturing 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 communities at proximity to industries like quarries and sand works.
