Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:INHAL: SILICOSIS-EXPOS TO RESPIRABLE
    CRYSTALLINE SILICA (QUARTZ) CAN CAUSE SILICOSIS, FIBROSIS
    (SCARRING) OF LUNGS. SILICOSIS MAY BE PROGRESSIVE; IT MAY LEAD TO
    DISABILITY & DEATH. CANCER:THERE IS EVI DENCE THAT RESPIRABLE
    CRYSTALLINE SILICA IS A CARCIN. SCLERODERMA: THERE IS EVIDENCE THAT
    EXPOS TO RESPIRABLE SILICA/DISEASE SILICOSIS IS ASSOCIATED
    W/INCREASED INCIDENCE OF SCLERODERMA, AN IMMUNE SYS  DISORDER
    MANIFESTED BY FIBROSIS (SCARRING) OF LUNGS, SKIN & OTHER INTERNAL
    ORGS. TUBERCULOSIS: INDIVIDUALS W/SILICOSIS ARE PREDISPOSED TO

    STUDIES SUGGESTING	(EFTS OF OVEREXP)
Explanation of Carcinogenicity:SILICA, CRYSTALLINE - QUARTZ: IARC
    MONOGRAPHS, VOL 68, PG 41, 1997:  GRP 1.  NTP 8TH ANNUAL REPORT ON
    CARCINOGENS, 1998: REASONABLY ANTICIPATED TO BE HUMAN CARCINOGEN.
Effects of Overexposure:HLTH HAZ: EXPOS TO RESPIRABLE CRYSTALLINE
    SILICA/DISEASE SILICOSIS IS ASSOCD W/INCRD INCIDENCE OF KIDNEY
    LESIONS. NOTE: CRYSTALLINE SILICA EXISTS IN SEVERAL FORMS, MOST
    COMMON OF WHICH IS QUARTZ. IF C RYSTALLINE SILICA (QUARTZ) IS
    HEATED TO MORE THAN 870C IT CAN CHANGE TO FORM OF CRYSTALLINE
    SILICA KNOWN AS TRYDIMITE, & IF CRYSTALLINE SILICA (QUARTZ) IS
    HEATED TO MORE THAN 1470C, IT CAN CHANGE TO   FORM A CRYSTALLINE
    SILICA KNOWN AS CRISTOBALITE. CRYSTALLINE SILICA AS TRYDIMITE &
    CRISTOBALITE ARE MORE FIBROGENIC THAN CRYSTALLINE SILICA AS QUARTZ.
