Explanation of Carcinogenicity:SILICA, CRYSTALLINE-QUARTZ: IARC
MONOGRAPHS, VOL 68, PG 41, 1997:GROUP 1. NTP 8TH ANNUAL REPORT ON
CARCINOGENS, 1998. REASONABLY ANTICIPATED TO BE HUMAN CARCINOGEN.
Effects of Overexposure:SEE HEALTH HAZARD.

First Aid:EYES & SKIN: IN CASE OF CONTACT, IMMEDIATELY FLUSH WITH
COPIOUS AMOUNTS OF WATER FOR AT LEAST 15 MINUTES WHILE REMOVING
CONTAMINATED CLOTHING AND SHOES. INHALATION: REMOVE TO FRESH AIR.
IF NOT BREATHI NG GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS
DIFFICULT, GIVE OXYGEN. INGESTION: WASH OUT MOUTH WITH WATER
PROVIDED PERSON IS CONSCIOUS. CALL A PHYSICIAN. WASH CONTAMINATED
CLOTHING BEFORE REUSE.

Extinguishing Media:NONCOMBUSTIBLE. USE EXTINGUISHING MEDIA APPROPRIATE
TO SURROUNDING FIRE CONDITIONS.
Fire Fighting Procedures:USE NIOSH APPROVED SCBA & FULL PROTECTIVE
EQUIPMENT .
Unusual Fire/Explosion Hazard:EMITS TOXIC FUMES UNDER FIRE CONDITIONS.
THIS MATERIAL, LIKE MOST MATERIALS IN POWDER FORM, IS CABLE OF
CREATING A DUST EXPLOSION.

Spill Release Procedures:WEAR NIOSH APPROVED SELF-CONTAINED BREATHING
APPARATUS, RUBBER BOOTS AND HEAVY RUBBER GLOVES. SWEP UP, PLACE IN
A BAG AND HOLD FOR WASTE DISPOSAL. AVOID RAISING DUST. VENTILATE
AREA AND WASH SPILL SIT E AFTER MATERIAL PICKUP IS COMPLETE.

Respiratory Protection:NIOSH APPROVED RESPIRATOR IN NONVENTILATED AREAS
AND/OR FOR EXPOSURE ABOVE THE ACGIH TLV.

Protective Gloves:RUBBER GLOVES.
Eye Protection:ANSI APPROVED CHEMICAL WORKERS GOGGLES .
Other Protective Equipment:EYE WASH AND DELUGE SHOWER MEETING ANSI
DESIGN CRITERIA .
Work Hygienic Practices:WASH THOROUGHLY AFTER HANDLING.
Supplemental Safety and Health
MATLS TO AVOID: THROUGH THERMAL DECOMPOSITION OF SODIUM BOROHYDRIDE.
SPONTANEOUS COMBUSTION IN AIR OCCURS AT 90-100'C. THE PRESENCE OF
MOISTURE IN THE AIR CAUSES THE IGNITION TO OCCUR MORE READILY.

Appearance and Odor:SOLID.

Stability Indicator/Materials to Avoid:YES
OXIDIZING AGENTS. MIXING SOLID SODIUM BOROHYDRIDE W/CHARCOAL (ACTIVATED
CARBON) IN AIR PROMOTES OXIDATION OF SODIUM BOROHYDRIDE, PRODUCING
SELF HEATING REACTION THAT MAY RESULT IN IGNTION OF CHARCOAL & IN
PRODUCTION OF HYDR
Hazardous Decomposition Products:TOXIC FUMES OF : CARBON MONOXIDE,
CARBON DIOXIDE.
Conditions to Avoid Polymerization:WILL NOT OCCUR.

Waste Disposal Methods:BURY IN A LANDFILL SITE APPROVED FOR THE
DISPOSAL OF CHEMICAL AND HAZARDOUS WASTES. OBSERVE ALL FEDERAL,
STATE, AND LOCAL ENVIRONMENTAL REGULATIONS.

Toxicological Information:TO THE BEST OF MFR'S KNOWLEDGE THE CHEMICAL,
PHYSICAL, AND TOXICOLOGICAL PROPERTIES HAVE NOT BEEN THOROUGHLY
INVESTIGATED. ADDITIONAL INFORMATION: PROLONGED INHALATION OF
CRYSTALLINE SILICA MAY RESULT IN SILICOSIS, A DISABLING PULMONARY
FIBROSIS CHARACTERIZED BY FIBROTIC CHANGES & MILIARY NODULES IN
LUNGS, DRY COUGH, SHORTNESS OF BREATH, EMPHYSEMA, DECREASED CHEST
EXPANSION & INCREASED SUSCEPTIBIL ITY TO TUBERCULOSIS. IN ADVANCED
STAGES, LOSS OF APPETITE, PLEURITIC PAIN, & TOTAL INCAPACITY TO
WORK. ADVANCED SILICOSIS MAY RESULT IN DEATH DUE TO CARDIAC FAILURE
OR DESTRUCTION OF LUNG TISSUE.
