& PLACED IN SUITABLE CONTAINER FOR DISPOSAL. PERSONAL
PRECAUTIONS-WEAR GOGGLES IF RELEASE CREATES CONDITIONS WHERE EYE
CONTACT IS PROBABLE. VENTILATE ARE A IF NECESSARY. IF USER
OPERATIONS GENERATE DUST, THEN AN APPROVED RESPIRTAOR FOR
DUST/MISTS IS RECOMMENDED. ENVIRONMENTAL PRECAUTIONS-NONE.

Handling and Storage Precautions:HANDLING: AVOID CONTACT WITH SKIN AND
EYES. AVOID CREATING DUST. DO NOT BREATHE DUST. STORAGE: PRODUCT

TAKEN USING THIS MATERIAL IN PRESENCE OF FLAMMABLE OR EXPLOSI VE
GASES AND LIQUIDS

Respiratory Protection:AN APPROVED AIR-PURIFYING RESPIRATOR (APR) FOR
PARTICULATES MAY BE APPROPRIATE TO CONTROL EXPOSURE TO DUST.
PROTECTION BY AIR-PURIFYING RESPIRATORS IS LIMITED. USE A
POSITIVE-PRESSURE, AIR SUPPLIED RE SPIRATOR IF ANY POTENTIAL FOR
UNCONTROLLED RELEASE, EXPOSURE LEVELS ARE NOT KNOWN, OR WHERE
AIR-PURIFYING RESPIRATORS MAY NOT PROVIDE ADEQUATE PROTECTION.
Ventilation:IF USER OPERATIONS GENERATE DUST, FUME, OR MIST. USE
VENTILATION TO MINIMIZE DUST LEVELS.
Protective Gloves:BARRIER CREAM APPLICATION PRIOR TO SKIN EXPOSURE MAY
ASSIST IN SILICA REMOVAL .
Eye Protection:SAFETY GLASSES RECOMMENDED. GOGGLES MAY BE NECESSARY AT
HIGH DUST CONCENTRATION
Other Protective Equipment:DRYING MAY OCCUR. BARRIER CREAM APPLICATION
PRIOR TO SKIN EXPOSURE MAY ASSIST IN THE REMOVAL OF SILICA FROM THE
SKIN. WEAR APPROPRIATE CLOTHING TO MINIMIZE SKIN CONTACT.
Work Hygienic Practices:WASH EXPOSED SKIN FREQUENTLY. GOOD PRACTICES
SHOULD BE FOLLOWED IN REGARD TO WORK CLOTHING.
Supplemental Safety and Health
RESPIRATORY PROTECTION-USE OF RESPIRATORS MUST INCLUDE A COMPLETE
RESPIRATORY PROTECTION PROGRAM IN ACCORDANCE WITH NATIONAL
STANDARDS AND CURRENT BEST PRACTICES.
