Extinguishing Media:USE ALCOHOL TYPE AQUEOUS  FILM FORMING FOAM FOR
    LARGE FIRES. USE CO2 OR DRY CHEMICAL FOR SMALL FIRES.
Fire Fighting Procedures:WATER MAY BE INEFEFCTIVE BUT SHOULD BE USED TO
    COOL FIRE-EXPOSED STRUCTURES & VESSELS. USE WATER SPRAY FOR LARGE
    FIRES. WATER SPRAY MAY BE USED TO REDUCE THE INTENSITY OF FLAMES &
    DILUTE SPILLS TO NON -FLAMMABLE MIXTURE. WEAR FULL FIRE FIGHTING
    TURN-OUT GEAR & NIOSH-APPROVED SCBA.

    REACTIVITY:0.

==================  Accidental Release Measures  ==================

Spill Release Procedures:ELIMINATE IGNITION SOURCES. WEAR APPROPRIATE
    PERSONAL PROTECTIVE GEAR. CONTAIN SPILL. WATER FOG MAY REDUCE
    VAPORS. NOTIFY AUTHORITIES. PLACE LEAKING CONTAINERS IN
    WELL-VENTILATED AREA. CLEAN SMALL SPI LLS WITH NON-FLAMMABLE
    ABSORBENT. CLEAN-UP BY VACUUMING OR SWEEPING. KEEP UNECESSARY
    PEOPLE AWAY. ISOLATE & DENY ENTRY. STAY UPWIND. ISOLATE FOR 800
    METERS OR O.5 MILES ALL DIRECTIONS.
Neutralizing Agent:NO DATA PROVIDED BY MANUFACTURER

======================	Handling and Storage  ======================

Handling and Storage Precautions:USE WITH ADEQUATE VENTILATION. KEEP
    CONTAINERS CLOSED WHEN NOT IN USE. ALWAYS OPEN CONTAINERS SLOWLY TO
    ALLOW EXCESS PRESSURE TO VENT. AVOID BREATHING VAPOR. AVOID CONTACT
    WITH SKIN, EYES OR CLOTHES.
Other Precautions:KEEP ALL CONTAINERS TIGHTLY CLOSED WHEN NOT IN USE.
    STORE OUT OF DIRECT SUNLIGHT & ON AN IMPERMEABLE FLOOR. DO NOT
    STORE WITH INCOMPATIBLE MATERIALS. PRODUCT MAY GENERATE STATIC
    DISCHARGE. GROUND/BOND  EQUIPMENT WHEN TRANSFERRING MATERIAL.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:BASED ON WORKPLACE CONTAMINANT LEVEL AND WORKING
    LIMITS OF THE RESPIRATOR, USE A RESPIRATOR APPROVED BY NIOSH.
Ventilation:LOCAL VENTILATION IS PREFERRED. EXPLOSION-PROOF EQUIPMENT
    SHOULD BE USED IN MECHANICAL VENTILATION SYSTEM.
Protective Gloves:BUTYL RUBBER IS RECOMMENDED.
Eye Protection:CHEMICAL GOGGLES.
Other Protective Equipment:SAFETY SHOWER AND EYEBATH SHOULD BE READILY
    AVAILABLE.
Work Hygienic Practices:WASH THOROUGHLY WITH SOAP & WATER AFTER
    HANDLING. DECONTAMINATE SOILED CLOTHING THOROUGHLY BEFORE RE-USE.
