Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Nonoccupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as nonindustrial sources.
The Silica Exposure Control Plan applies to all Purdue University employees who are expected to be exposed to respirable crystalline silica as outlined in section 4; or through other means, which are determined by Radiological and Environmental Management (REM) or their supervisor.
Once we know how much air is being breathed, how much dust is contained within that air, and how much of that dust is respirable silica, we still need to factor the amount of time that air and dust is being inhaled. We can use what we''ve learned so far to determine the total maximum silica exposure for a person over an eighthour period.
Learn about crystalline silica (quartz dust), which can raise your risk of lung cancer. Crystalline silica is present in certain construction materials such as concrete, masonry, and brick and also in commercial products such as some cleansers, cosmetics, pet litter, talcum powder, caulk, and paint.
Step 2. How do you plan to control the dust? Select the type of equipment and dust control you plan to use for each material and task you selected in Step 1. Not Sure – Perform Air Monitoring.
