Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:ACUTE: CONCRETE MASONRY PRODS MAY
    RELEASE RESPIRABLE CRYSTALLINE QUARTZ DURING USE. PRLNGD EXPOS TO
    RESPIRABLE CRYSTALLINE QUARTZ MAY CAUSE DELAYED (CHRONIC) LUNG
    INJURY (SILICOSIS). ACUTE/RAPIDLY DEV ELOPING SILICOSIS MAY OCCUR
    IN SHORT PERIOD OF TIME IN HEAVY EXPOSURE. SILICOSIS IS FORM OF
    DISABLING (EFTS OF OVEREXP)
Explanation of Carcinogenicity:CRYSTALLINE SILICA-QUARTZ: IARC MONO,
    VOL 68, 1997: GROUP 1. NTP 7TH ANNUAL RPT ON CARCIN, 1994: ANTIC TO
    BE CARCIN.
