    MAY CAUSE IRREGULAR HEARTBEATS. PERSONS WITH PRE-EXISTING HEART
    DISORDERS MAY BE MORE SUSCEPTIBLE.

=======================  First Aid Measures  =======================

Eyes: MOVE VICTIM TO FRESH AIR. FLUSH EYES WITH  WATER. IF
    SYMPTOMS PERSIST, SEEK MEDICAL ATTENTION. SKIN: REMOVE CONTAMINATED
    SHOES AND CLOTHING. WASH AFFECTED AREA  WITH SOAP AND WATER. IF
    IRRITATIO N DEVELOPS AND PERSISTS, SEEK MEDICAL ATTENTION.
    INHALATION:  MOVE VICTIM TO FRESH AIR. IF SYMPTOMS PERSIST, SEEK
    MEDICAL ATTENTION. IF NOT BREATHING,  BEGIN ARTIFICIAL RESPIRATION.
    IF BREATHING DIFFI CULT, GIVE OXYGEN BY QUALIFIED PERSONNEL. SEEK
    MEDICAL ATTENTION. INGESTION: ASPIRATION HAZARD: DO NOT INDUCE
    VOMITING OR GIVE ANYTHING BY MOUTH. THIS MATERIAL CAN ENTER LUNGS
    AND CAUSE SEVERE LUNG DA MAGE. GET MEDICAL ATTENTION.

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

Flash Point Method:TCC

Autoignition Temp:=260.C, 500.F
Lower Limits:1
Upper Limits:8
Extinguishing Media:DRY CHEMICAL, CARBON DIOXIDE, HALON, OR FOAM 
    RECOMMENDED. WATER SPRAY RECOMMENDED TO COOL OR PROTECT EXPOSED
    MATERIALS OR STRUCTURES. WATER MAY BE INEFFECTIVE FOR
    EXTINGUISHMENT.
Fire Fighting Procedures:FIRE FIGHTERS SHOULD WEAR BUNKER GEAR, SELF
    CONTAINED BREATHING APPARATUS, APPROPRIATE PROTECTIVE EQUIPMENT.
    MOVE CONTAINERS FROM DANGER AREA. WATER SPRAY MAY BE USEFUL IN
    MINIMIZING OR DISPERSING VAP ORS. COOL EQUIPMENT EXPOSED TO FIRE
    WITH WATER. AVOID SPREADING BURNING LIQUID WITH WATER FOR COOLING
    PURPOSES.
Unusual Fire/Explosion Hazard:MATERIAL FLAMMABLE. CAN BE IGNITED BY
    HEAT, SPARKS, FLAMES, OTHER SOURCES OF IGNITION. VAPORS MAY
    TRAVELTO DISTANT IGNITION SOURCE, IGNITE, FLASHBACK, OR EXPLODE.
    MAY CREATE VAPOR/AIR EXPLOSION HAZARD  INDOORS, OUTDOORS, IN
    SEWERS. VAPORS HEAVIER THAN AIR, ACCUMULATE IN LOW AREAS.
    CONTAINERS CAN EXPLODE IN HEAT OF FIRE.

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

Spill Release Procedures:ELIMINATE IGNITION SOURCES. USE SPARK-PROOF
    EQUIPMENT. WEAR PROTECTIVE EQUIPMENT AND RESPIRATORY PROTECTION. 
    PREVENT SPILL FROM ENTERING SEWERS, STORM DRAINS,  NATURAL
    WATERWAYS. DIKE SPILL FOR LATER  RECOVERY OR DISPOSAL. NOTIFY FIRE
    AUTHORITIES AND FEDERAL, STATE, LOCAL AGENCIES. NOTIFY NATIONAL
    RESPONSE CENTER (800-424-8802) IF MATERIAL HAS ENTERED NAVIGABLE
    WATERS, CONTIGUOUS ZONE, SHORELINES.
Neutralizing Agent:NONE PROVIDED BY MFR.

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

Handling and Storage Precautions:OPEN CONTAINER SLOWLY TO RELIEVE
    PRESSURE. BOND AND GROUND ALL EQUIPMENT WHEN TRANSFERRING PRODUCT.
    VAPOR CAN BE IGNITED BY STATIC DISCHARGE. USE OF EXPLOSION-PROOF
    EQUIPMENT IS RECOMMENDED AND MAY BE  REQUIRED. FOLLOW PROPER ENTRY
    PROCEDURES FOR ENTERING CONFINED SPACES.
Other Precautions:WEAR RESPIRATORY PROTECTION WHEN EXPOSURE LIMITS
    EXCEEDED. DO NOT WEAR CONTAMINATED CLOTHING, SHOES. "EMPTY"
    CONTAINERS RETAIN RESIDUE AND MAY BE DANGEROUS. DO NOT PRESSURIZE,
    CUT, WELD, BRAZE, DRILL,  GRIND, EXPOSE SUCH CONTAINERS TO HEAT,
    FLAME, SPARKS, SOURCES OF IGNITION. THEY MAY EXPLODE AND CAU SE
    INJURY OR DEATH.

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

Respiratory Protection:THE USE OF RESPIRATORY PROTECTION IS ADVISED
    WHEN CONCENTRATIONS ARE EXPECTED TO EXCEED THE ESTABLISHED EXPOSURE
    LIMITS. DEPENDING ON THE AIRBORNE CONCENTRATION, USE A RESPIRATOR
    WITH APPROPRIATE CART RIDGES (NIOSH APPROVED, IF AVAILABLE) OR
    SUPPLIED-AIR EQUIPMENT.
Ventilation:PROVIDE ADEQUATE VENTILATION TO MAINTAIN AIRBORNE
    CONCENTRATIONS BELOW THE ESTABLISHED EXPOSURE LIMITS. PROVIDE
    EXPLOSION PROOF EQUIPMENT AND ELECTRICAL SYSTEM.
Protective Gloves:GLOVES IMPERMEABLE TO THE SPECIFIC MATERIAL HANDLED
    IS ADVISED.
