=====================  Fire Fighting Measures  =====================

Flash Point:NONFLAMMABLE
Autoignition Temp:=440.C, 824.F
Extinguishing Media:NONFLAMMABLE; USE AGENT MOST APPROPRIATE TO

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

Spill Release Procedures:VACUUM OR SWEEP UP MATERIAL AND PLACE INTO A
    SUITABLE DISPOSAL CONTAINER. AVOID RUNOFF INTO STORM SEWERS AND
    DITCHES WHICH LEAD TO WATERWAYS. CLEAN UP SPILLS IMMEDIATELY,
    OBSERVING PRECAUTIONS.  AVOID  GENERATING DUSTY CONDITIONS. PROVIDE
    VENTILATION. USE PROPER PERSONAL PROTECTIVE EQUIPMENT.
Neutralizing Agent:NO DATA PROVIDED BY RESPONSIBLE PARTY.

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

Handling and Storage Precautions:WASH AFTER HANDLING. REMOVE
    CONTAMINATED CLOTHING & WASH BEFORE REUSE. USE ONLY IN WELL 
    VENTILATED AREA. MINIMIZE DUST GENERATION & ACCUMULATION. AVOID
    CONTACT WITH EYES, SKIN, CLOTHING. DO NOT INGES T OR INHALE.
    DISCARD CONTAMINATED SHOES.
Other Precautions:KEEP CONTAINER CLOSED WHEN NOT IN USE. STORE IN A
    TIGHTLY CLOSED CONTAINER IN A COOL, DRY, WELL-VENTILATED AREA AWAY
    FROM INCOMPATIBLE SUBSTANCES.

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

Respiratory Protection:A REPIRATORY PROTECTIVE PROGRAM THAT MEETS
    OSHA'S 29 CFR 1910.134 AND ANSI Z88.2 REQUIREMENTS OR EUROPEAN
    STANDARD EN 149 MUST BE FOLLOWED WHENEVER WORKPLACE CONDITIONS
