Extinguishing Media:USE WATER SPRAY, CARBON DIOXIDE (CO2), ALCOHOL FOAM
    OR DRY CHEMICAL. USE WATER SPRAY TO COOL FIRE EXPOSED CONTAINERS.
Fire Fighting Procedures:WEAR FULL PROTECTIVE CLOTHING AND NIOSH-
    APPROVED SELF-CONTAINED BREATHING APPARATUS WITH FULL FACEPIECE
    OPERATED IN THE POSITIVE PRESSURE MODE.
Unusual Fire/Explosion Hazard:DIRECT CONTACT WITH MOISTURE OR WATER CAN
    CAUSE VIOLENT EXOTHERMIC REACTION GENERATING SUFFICIENT HEAT TO
    IGNITE NEARBY COMBUSTIBLE MATERIALS.

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

Spill Release Procedures:WEAR PROTECTIVE EQUIPMENTS. VACCUM OR SWEEP UP
    AND PLACE IN APPROVED CONTAINERS FOR DISPOSAL. AVOID GENERATING
    DUSTY CONDITIONS. NEUTRALIZE REMAINING TRACES OF MATERIAL WITH
    ACID. WASH SPILL AREA WITH	WATER TO REMOVE RESIDUAL CONTAMINATION.
Neutralizing Agent:DILUTE INORGANIC ACID (SULFURIC, HYDROCHLORIC,
    PHOSPHORIC, NITRIC ACIDS).

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

Handling and Storage Precautions:STORE IN TIGHTLY CLOSED CONTAINER IN
    DRY PLACE AWAY FROM FLAMMABLE AND INCOMPATIBLE MATERIALS. KEEP OUT
    OF REACH OF CHILDREN.
Other Precautions:USE WITH ADEQUATE VENTILATION. DO NOT GET IN EYES, ON
