Medical Cond Aggravated by Exposure:MAY CAUSE ASTHMATIC ATTACKS.

First Aid:EYES: FLUSH WITH WATER FOR 15 MINUTES; OCCASIONALLY LIFTING
EYELIDS. GET MEDICAL AID. SKIN: GET MEDICAL AID. FLUSH SKIN WITH
SOAP AND WATER FOR 15 MINUTES WHILE REMOVING CONTAMINATED CLOTHING
AND SHOE S. WASH CLOTHING BEFORE REUSE. DESTROY CONTAMINATED SHOES.

MOUTH TO AN UN CONSCIOUS PERSON. GET MEDICAL AID. INHALATION: GET
MEDICAL AID. MOVE TO FRESH AIR. IF BREATHING DIFFICULT, GIVE
OXYGEN. IF NOT BREATHING GIVE ARTIFICIAL RESPIRATION USING OXYGEN
AND SUITABLE MECHANIC AL DEVICE SUCH AS BAG AND MASK.

Extinguishing Media:USE WATER ONLY! DO NOT USE DRY CHEMICAL, CARBON
DIOXIDE, HALOCARBONS, AND SODIUM BICARBONATE.
Fire Fighting Procedures:AS IN ANY FIRE, WEAR A SELF-CONTAINED
BREATHING APPARATUS IN PRESSURE-DEMAND, MSHA/NIOSH APPROVED OR
EQUIVALENT, AND FULL PROTECTIVE GEAR. STRONG OXIDIZER. CONTACT WITH
COMBUSTIBLE MATERIALS MAY CAUSE A FIRE. COOL CONTAINERS WITH
FLOODING QUANTITIES OF WATER UNTIL WELL AFTER FIRE IS OUT.
Unusual Fire/Explosion Hazard:DURING A FIRE, IRRITATING AND HIGHLY
TOXIC GASES MAY BE GENERATED BY THERMAL DECOMPOSITION. USE WATER
SPRAY TO KEEP FIRE-EXPOSED CONTAINERS COOL. CONTAINERS MAY EXPLODE
IN THE HEAT OF A FIRE.

Spill Release Procedures:USE PROPER PERSONNEL PROTECTIVE EQUIPMENT.
CLEAN UP SPILLS, OBSERVING ALL PRECAUTIONS. SWEEP UP OR ABSORB
MATERIAL, THEN PLACE INTO A SUITABLE CLEAN, DRY, CLOSED CONTAINER
FOR DISPOSAL. AVOID GENERATI NG DUSTY CONDITIONS. PROVIDE
VENTILATION. DO NOT USE COMBUSTIBLE MATERIALS SUCH AS PAPER TOWELS
TO CLEAN UP SPILL.

Handling and Storage Precautions:HANDLING: WASH AFTER HANDLING. USE
WITH ADEQUATE VENTILATION. MINIMIZE DUST GENERATION AND
ACCUMULATION. DO NOT GET INTO EYES, ON SKIN, OR CLOTHING. KEEP
CONTAINER CLOSED. AVOID CONTACT WITH HEAT, SPA RKS, FLAME. AVOID
CONTACT WITH CLOTHING, OTHER COMBUSTIBLE MATERIALS. DO NOT INGEST
OR INHALE.
Other Precautions:STORAGE: KEEP AWAY FROM SOURCES OF IGNITION. DO NOT
STORE NEAR COMBUSTIBLE MATERIALS. STORE IN TIGHTLY CLOSED
CONTAINER, IN A COOL, DRY, WELL-VENTILATED AREA AWAY FROM
INCOMPATIBLE SUBSTANCES. KEEP AW AY FROM REDUCING AGENTS.

Respiratory Protection:FOLLOW OSHA RESPIRATOR REGULATIONS FOUND IN
29CFR 1910.134 OR EUROPEAN STANDARD EN 149. ALWAYS USE A NIOSH OR
EUROPEAN STANDARD EN 149 APPROVED RESPIRATOR WHEN NECESSARY.
Ventilation:USE ADEQUATE GENERAL OR LOCAL EXHAUST VENTILATION TO KEEP
AIRBORNE CONCENTRATIONS BELOW THE PERMISSIBLE EXPOSURE LIMITS.
Protective Gloves:WEAR APPROPRIATE PROTECTIVE GLOVES TO PREVENT SKIN
EXPOSURE.
Eye Protection:PROTECTIVE EYEGLASSES OR CHEMICAL SAFETY GOGGLES PER
29CFR 1910.133 OR NN166.
Other Protective Equipment:WEAR APPROPRIATE PROTECTIVE CLOTHING TO
PREVENT SKIN EXPOSURE.
