======================= SECTION V -- REACTIVITY DATA ================================
STABILITY: STABLE
CONDITIONS TO AVOID
CONTACT WITH POWERFUL OXIDIZING AGENTS SUCH AS FLUORINE, CHLORINE, TRIFLUORIDE, MANGANESE, TRIOXIDE, OXYGEN TRIFLUORIDE.
INCOMPATIBILITY (MATERIALS TO AVOID)
CAN REACT VIGOROUSLY WITH STRONG OXIDIZING AGENTS -- SEE CONDITIONS TO AVOID.
HAZARDOUS DECOMPOSITION OR BYPRODUCTS

HAZARDOUS POLYMERIZATION :
WILL NOT OCCUR
==================== SECTION VI -- HEALTH HAZARD DATA ==============================
INHALATION HEALTH RISKS AND SYMPTOMS OF EXPOSURE
PROLONGED EXPOSURE TO RESPIRABLE CRYSTALLINE QUARTZ MAY CAUSE DELAYED LUNG INJURY(SILICOSIS). ACUTE OR RAPIDLY DEVELOPING SILICOSIS MAY OCCUR IN A SHORT PERIOD OF TIME IN HEAVY EXPOSURE IN SOME APPICATIONS SUCH AS SAND BLASTING.
SKIN AND EYE CONTACT HEALTH RISKS AND SYMPTOMS OF EXPOSURE
MAY CAUSE REDDENING OF THE EYES OF EYE IRRITATION FROM AIRBORNE PARTICLES.
SKIN ABSORPTION HEALTH RISKS AND SYMPTOMS OF EXPOSURE
NONE KNOWN.
INGESTION HEALTH RISKS AND SYMPTOMS OF EXPOSURE
NONE KNOWN.
HEALTH HAZARDS (ACUTE AND CHRONIC)
MAY CAUSE DELAYED SILICOSIS OR RAPID SILICOSIS IN SOME OCCUPATIONS SUCH AS SANDBLASTING, SILICOSIS IS A FORM OF A DISABLING PULMONARY FIBROSIS WHICH CAN BE PROGRESSIVE AND COULD LEAD TO DEATH, INHALATION MAY LEAD TO LUNG SCARRING AND MASSIVE FIBROSIS WHICH COULD BE ACCOMPANIED BY RIGHT HEART ENLARGEMENT, HEART FAILURE, OR PULMONARY FAILURE. SMOKING AGGREVATES THE EFFECTS OF EXPOSURE.
CARCINOGENICITY: NTP?
NO IARC MONOGRAPHS? NO OSHA REGULATED? NOIARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC RISK OF CHEMICALS TO HUMANS (VOLUME 42 1987 CONCLUDES THAT THERE IS SUFFICIENT EVIDENCE FOR THE CARCINOGENICITY OF CRYSTALLINE SILICA TO ANIMALS AND LIMITED EVIDENCE TO HUMANS) IARC CLASS 2A
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE
PULMONARY CONDITIONS OR OTHER SIMILAR AILMENTS CAN BE AGGRAVATED BY EXPOSURE.
EMERGENCY AND FIRST AID PROCEDURES
EYES: FLUSH EYES WITH WATER FOR AT LEAST FIFTEEN MINUTES AND CONSULT A PHYSICIAN. SKIN: SKIN CONTACT WILL NORMALLY CAUSE NO HEALTH RISKS. INHALATION: REMOVE VICTIM TO FRESH AIR AREA AND ADMINISTER OXYGEN IF NECESSARY, CONSULT A PHYSICIAN IF CONDITIONS WARRANT. IF INGESTED CONSULT A PHYSICIAN.
