Crystalline silica inhaled in the form of quartz
or cristobalite from occupational sources is
carcinogenic to humans (Group1). Avoid breathing
dust and contact with skin and eyes. Use NIOSH
certied dust respirator (N95). This type of
respirator is based on the OSHA requirements
for cristobalite at the time this document was
written. Other types of respirators may be needed
depending on the job site conditions. Current
