Silicosis

Trades affected by Silicosis

Silica dust is released during operations in which rocks, sand, concrete and some ores are crushed or broken. Work in mines, quarries, foundries, and construction sites, in the manufacture of glass, ceramics, and abrasive powders, and in masonry workshops are particularly risky.

Sandblasting is one of the high-risk operations for silicosis. Any abrasive blasting, even if the abrasive does not contain silica, may pose a silicosis hazard when it is used to remove materials that contain silica, such as remains of sand moulds from metal castings. Some operations, like dry sweeping, the clearing of sand or concrete, or the cleaning of masonry with pressurized air can generate large dust clouds. Thus even in open air these activities can be hazardous.
