Determining the quantity of crystalline silica in air
Silica is a natural occurring mineral found in rocks and stone commonly used in different building materials such a bricks and concrete. Workers will be exposed to silica when drilling, cutting or otherwise performing operations whereby these materials are being broken and are releasing dust. Both OSHA and NIOSH have identified exposure to silica as a health hazard as dust containing crystalline forms of silica (quartz, cristobalite, and tridymite) may cause silicosis. New Permissible exposure limit (PEL) for crystalline silica was introduced in 2016 highlighting the hazard this kind of exposure presents.
