Overview of Silica Exposure

Glassware by Shelley EnszMany occupations and even some hobbies can create silica dust, which can then cause severe health problems and even death. Workers in these industries (or hobby enthusiasts) are advised to take all necessary safety precautions to prevent inhalation of crystalline silica. Sometimes the silica particles can be so tiny that they cannot even be seen in the air, thus sometimes causing people to lapse in wearing protection. The take-home message is that people in these industries should make every effort to avoid inhaling silica (whether or not it is noticeable in the air.)

Occupations Associated with Silica Exposure

Silica Exposure can occur to workers and bystanders in the following type of industries:

abrasives (manufacturing and use)
ceramics, clay, pottery
detergent manufacturing
foundry work
glass manufacturing

Inhaled Crystalline Silica

Determining Silica Exposure Because silica is so abundant in our natural resources, it's possible that you use silica and don't even know it! There is potential for danger ONLY when crystalline silica particles are in the air. There may be materials that contain silica but if the operations on those materials do not generate dust, there is little chance of inhaling the silica. Likewise, there may be silica particles in the air even though you don't see any dust. U.S. Department of Labor, Occupational Safety & Health Administration.

Mortality from Occupational Silica Exposure

Deaths from Silica in the Workplace The first column is the occupational title. The second column (PMR) is the observed number of deaths from silicosis per occupation divided by the expected number of deaths. U.S. Department of Labor, Occupational Safety & Health Administration.
