Silica is one of the most common hazards on a worksite, particularly in the construction, oil and gas, manufacturing, and agriculture industries. Silica dust can cause silicosis, a serious and irreversible lung disease. 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 can settle in their lungs.
Respirable dust and air samples are collected in accordance to National Institute for Occupational Safety and Health (NIOSH) methods using personal sampling pumps attached to those workers most likely to be at risk, to evaluate exposure throughout an 8-hour work day.
