ACGIH TLV: 0.1 MG/M3

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
DEVELOP TUBERCULOSIS. NEPHROTOXICITY: THERE ARE SEVERAL RECEN T
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.
OSHA PEL FOR CRYSTALLINE SILICA AS TRYDIMITE & CR ISTOBALITE ARE
MORE FIBROGENIC (SUPDAT)
Medical Cond Aggravated by Exposure:THE CONDITION OF INDIVIDUALS WITH
LUNG DISEASE (E.G. BRONCHITIS, EMPHYSEMA, CHRONIC OBSTRUCTIVE
PULMONARY DISEASE) CAN BE AGGRAVATED BY EXPOSURE.

First Aid:INHALATION: NO SPECIFIC FIRST AID NECESSARY SINCE THE ADVERSE
HEALTH EFFECTS ASSOCIATED WITH EXPOSURE TO CRYSTALLINE SILICA
(QUARTZ) RESULT FROM CHRONIC EXPOSURES. IF THERE IS A GROSS
INHALATION OF CR YSTALLINE SILICA (QUARTZ), REMOVE THE PERSON
IMMEDIATELY TO FRESH AIR, GIVE ARTIFICIAL RESPIRATION AS NEEDED,
SEEK MEDICAL ATTENTION AS NEEDED. EYE CONTACT; WASH IMMEDIATELY
WITH WATER FOR AT LEAST 15 MINUTES. IF IRRITATION PERSISTS, SEEK
MEDICAL ATTENTION. SKIN: N/A. FLUSH WITH COPIOUS AMOUNTS OF WATER.
