Reports of Carcinogenicity:NTP:YES IARC:YES
Health Hazards Acute and Chronic:TARGET ORGANS: EYES, SKIN AND
RESPIRATORY SYSTEM. ACUTE: UPPER RESPIRATORY PHYSICIAL IRRITATION,
IRRITATION AND INFLAMMATION TO THE EYES ON CONTACT AND TO THE SKIN
ON PROLONGED CONTACT. CHRONIC: PROLO NGED/REPEATED INHALTION OF
RESPIRABLE CRYSTALINE SILICA MAY CAUSE DELAYED LUNG INJURY
(SILICOSIS).
Explanation of Carcinogenicity:NTP, CLASSIFIED SILICA, CRYSTALLINE AS A
SUBSTANCE WHICH MAY REASONABLY BE ANTICIPATED TO BE A CARCINOGEN.
IARC HAS CLASSIFIED SRYSTALLINE SILICA INHALED IN THE FORM OF
QUARTZ OR CRISTOBALITE FROM OCC UPATIONAL SOURCES AS CARCINOGENIC
TO HUMANS (GROUP 1).
Effects of Overexposure:EYE: MAY CAUSE TRANSIENT EYE IRRITATION. SKIN:
MAY CAUSE SKIN IRRITATION AT HUMID CONDITIONS. INGESTION. MAY CAUSE
TEMPORARY IRRITATION TO THE GASTROINTESTINAL TRACT. INHALATION:
DECLINE IN PULMONARY FUNCTION AND ABNORMAL CHEST X-RAY.

First Aid:EYE: FLUSH WITH LARGE AMOUNTS OF WATER FOR AT LEAST 15
MINUTES. DO NOT RUB EYES. SKIN: WASH AFFECTED AREA GENTLY WITH SOAP
AND WATER. SKIN CREAM OR LOTION AFTER WASHING MAY BE HELPFUL.
INGESTION: DO N OT INDUCE VOMITING, DRINK PLENTY OF WATER.
INHALATION: REMOVE AFFECTED PERSON TO CLEAN FRESH AIR. IF ANY OF
THE SYMTPOMS PERSIST, SEEK MEDICAL ATTENTION IMMEDIATELY.

Flash Point:=204.4C, 400.F
Extinguishing Media:WATER FOG, STEAM OR CARBON DIOXIDE.
Fire Fighting Procedures:WEAR IMPERVIOUS CLOTHING AND FULL FACE,
SELF-CONTAINED BREATHING EQUIPMENT.
Unusual Fire/Explosion Hazard:WATER STREAM MAY SPLATTER MOLTEN SULFUR.

Spill Release Procedures:AVOID CREATING AIRBORNE DUST. FOLLOW REOUTINE
HOUSEKEEPING PROCEURES. VACUUM ONLY WITH HEPA FILTERED EQUIPMENT.
IF SWEEPING IS NECESSRY, USE A DUST SUPPRESSANT AND PLACE MATERIAL
IN CLOSED CONTAINERS. DO NOT USE COMPRESSED AIR FOR CLEAN-UP.
PERSONNEL SHOUD WEAR GLOVES, GOGGLES AND APPROVED RESPIRATOR.

Handling and Storage Precautions:LIMIT USE OF POWER TOOLS UNLESS
INCONJUNCTION WWITH LOCAL EXHAUST. USE HAND TOOLS WHENEVER
POSSIBLE. FREQUENTLY CLEAN THE WORK AREA WITH HEPA FILTERED VACUUM
OR WET SWEEPING TO MINIMIZE THE ACCUMULATI ON OF DEBRIS. DO NOT USE
COMPRESSED AIR FOR CLEAN UP.
Other Precautions:LANDFILL: CHEMICAL ADDITIONS, PROCESSING OR OTHERWIDE
ALTERING THIS MATERIAL MAY MAKE THE WASTE MANAGEMENT INFORMATION
PRESENTED IN THIS MSDS INCOMPLETE, INACCURATE, OR OTHERWISE
INAPPROPRIATE. STORAG E: STORE IN ORIGINAL FACTORY CONTAINER IN A
DRY AREA. KEEP CONTAINER CLOSED WHEN NOT N USE.

Respiratory Protection:WHEN IT IS NOT POSSIBLE OR FEASIBLE TO REDUCE
AIRBORNE CRYSTALINE SILICAL OR PARTICULATE LEVELS BELOW THE PEL
THROUGH ENGINEERING CONTOLS. USE NIOSH CERTIFIED RESPIRATORS . IN
COMPLIANCE WITH OSHA RES PIRATORY PROTECTION STANDARD 29
CFR1910.134 AND 29 CFR1926.103, FOR THE PARTICULAR HAZARD OR
AIRBORNE CONCENTRATIONS TO BE ENCOUNTERED IN THE WORK ENVIRONMENT.
Ventilation:USE ENGINEERING CONTROLS SUCH AS VENTILATION AND DUST
COLLECTION DEVICES TO REDUCE AIRBORNE PARTICULATE CONCENTATIONS TO
THE LOWEST ATTAINABLE LEVEL.
Protective Gloves:RUBBER OR VINYL.
Eye Protection:GOGGLES/SAFETY GLASSES WITH SIDESHIELDS SHOULD BE WORN.
Other Protective Equipment:WEAR FULL BODY CLOTHING, GLOVES, HEAT AND
EYE PROTECTION.
Work Hygienic Practices:WASH CLOTHES SEPARATELY FROM OTHER CLOTHING.
RINSE WASHER AFTER USE. IF YOU TAKE WORK CLOTHING HOME, IT IS
RECOMMENDED YOU VACUUM CLOTHES WITH HEPA FILTERED VACUUM BEFORE
LEAVING WORK AREA.

Toxicological Information:TOXICOLOGY: CRYSTALLINE SILICA. THERE IS
SUFFICIENT EVIDENCE OF CARCONOGENICITY OF RESPIRABLE SILICA IN
EXPERIMENTAL ANIMALS (IARC MONOGRAPH; VOL. 42; 1987 AND IARC
MONOGRAPH; VOL. 68; 1997). INHALATI ON AND INTRACHEAL INSTALLATION
OF CRYSTALLINE SILICA IN RATS CAUSED LUNG CANCER; HOWEVER, STUDIES
IN OTHER SPECIES SUCH AS MICE AND HAMSTERS CAUSED NO LUNG CANCER.
CRYSTALLINE SILICA ALSO CAUSED FIBRO SIS IN RATS AND HAMSTERS IN
SEVERAL INHALATION AND INTRACHEAL INSTALLATION STUDIES.
