EYES: This material can irritate and burn human eyes following contact. The aggregate particles may cause corneal abrasions.
SKIN: Dryness, itching, rashes and burns can develop following contact with the skin. Skin abrasions can occur if material is rubbed against the skin. Dermatitis and skin sensitization can develop after repeated or prolonged exposure. This material is not absorbed through the skin.
INHALATION: Repeated inhalation of silica in excess of the TLV over extended periods can result in irreversible fibrosis of the lungs (silicosis). Overexposure to dusts can irritate the respiratory tract and cause damage to the mucous membranes of the upper respiratory tract.
INGESTION: No known toxic effects. May cause digestive tract irritation.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: No other clinical effects are known to be associated with this material.

From MSDS
The International Agency for Research on Cancer (IARC) classified crystalline silica inhaled in the form of quartz cristobalite from occupational sources as carcinogenic to humans. This assignment was based on a relatively large number of epidemiological studies that provided sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica.
