Silica exposure remains a serious threat to nearly 2 million workers, including more than 100,000 workers in high risk jobs such as abrasive blasting, foundry work, stonecutting, rock drilling, quarry work and tunneling. Crystalline silica has been classified as a human lung carcinogen.
Crystalline silica is one of the earth’s most common minerals, but exposure to it in dust form can be deadly. Inhalation of these fine particles through foundry, refractory, construction, brick, tile or stone trades, to name a few, can put workers at risk for a number of …
Assessment of work involving other types of grain dust 17 You may need to carry out a risk assessment of work activities involving exposure to other types of grain not included in the definition of grain dust, eg rice, sorghum, pulses (such as soya bean), peas and various oilseeds (such as rapeseed).
worker exposures to airborne silica dust, including . from quartz in stone. It covers the health effects of breathing silica dust, recommends ways to protect workers, and describes how OSHA and NIOSH can help employers effectively reduce silica dust exposures. Employers must ensure that workers are properly protected from exposure to silica.

This site provides information to help employers control exposure to dust in the workplace. You can also access further information on dust from this site. Dust is tiny, dry particles in the air and can be produced when materials are cut, drilled, demolished, sanded, shovelled, etc. This means many work activities can create dust.
It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust. As workers breathe in the dust the silica settles in their lungs. For information on protecting workers from harmful exposure to silica dust, see the resources section below, which includes a silica control tool.
The level of risk depends on the amount of exposure which is determined mainly by the materials and work methods used, the duration of the work and the controls in place. Are there exposure limits?
