Carcinogenicity
Not expected to be hazardous by OSHA criteria.
Exposure to respirable crystalline silica in the form of quartz or cristobalite from occupational
sources is listed by IARC and NTP as a lung carcinogen. Prolonged exposure to respirable
crystalline silica has been known to cause silicosis, a lung disease, which may be disabling.
While there may be a factor of individual susceptibility to a given exposure to a respirable silica
dust, the risk of contracting silicosis and the severity of the disease is clearly related to the
amount of respirable crystalline silica exposure and the length of time (usually years) of exposure.
