Medical Cond Aggravated by Exposure:PERSONS WITH PRE-EXISTING DISEASES
    INVOLVING THE EYES, SKIN, LUNGS OR CNS MAY BE AT INCREASED RISK
    FROM EXPOSURE.

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

First Aid:CALL PHYSICIAN IF SYMPTOMS PERSIST. EYE:IMMEDIATELY FLUSH
    WITH WATER FOR 15 MINUTES. HOLD EYELIDS OPEN. SKIN:WASH WITH SOAP &
    WATER. INHALED:REMOVE TO FRESH AIR. PROVIDE CPR/OXYGEN IF NEEDED.
    ORAL:IF  CONSCIOUS, INDUCE VOMITING USING IPECACSYRUP & WATER. CALL
    A PHYSICIAN/POISON CONTROL CENTER IMMEDIATELY. NEVER GIVE FLUID OR
    INDUCE VOMITING IF PATIENT IS UNCONSCIOUS OR HAS CONVULSIONS.

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

Flash Point Method:CC
Flash Point:16.0F,-8.9C
Autoignition Temp:Autoignition Temp Text:759F
Lower Limits:1.4%
Upper Limits:11.4%
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 PROTECTIVE CLOTHING AND NIOSH-APPROVED
    SELF-CONTAINED BREATHING APPARATUS. SEE 1990 EMERGENCY RESPONSE
    GUIDEBOOK, DOT P 5800.5.
Unusual Fire/Explosion Hazard:VAPOR IS HEAVIER THAN AIR AND CAN TRAVEL
    CONSIDERABLE DISTANCE TO A SOURCE OF IGNITION AND FLASH BACK.
    CONTAINERS MAY RUPTURE DUE TO VAPOR PRESSURE BUILDUP.

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

Spill Release Procedures:WEAR PROTECTIVE EQUIPMENT. ELIMINATE SOURCES
    OF IGNITION. VENTILATE AREA. CONTAIN SPILL. PICK UP SPILL WITH
    NON-FLAMMABLE ABSORBENT MATERIAL SUCH AS SAND. PLACE IN CONTAINER
    FOR DISPOSAL. PREVENT LIQU ID FROM ENTERING SEWERS, WATERWAYS OR
    LOW AREAS.
Neutralizing Agent:NOT RELEVANT

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

Handling and Storage Precautions:STORE IN COOL, DRY, WELL VENTILATED
    AREA AWAY FROM SOURCES OF IGNITION & INCOMPATIBLE MATERIALS. BOND
    AND GROUND CONTAINERS WHEN TRANSFERRING LIQUID.
Other Precautions:"EMPTY" CONTAINERS MAY RETAIN RESIDUE AND CAN BE
    DANGEROUS. DO NOT PRESSURIZE, CUT, WELD, BRAZE, SOLDER, DRILL,
    GRIND OR EXPOSE SUCH CONTAINERS TO HEAT, FLAME, SPARKS. THEY MAY
    EXPLODE AND CAUSE INJUR Y/DEATH. KEEP OUT OF REACH OF CHILDREN.

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

Respiratory Protection:IF ENGINEERING CONTROLS ARE INADEQUATE TO
    CONTROL VAPOR CONCENTRATIONS TO AN ACCEPTABLE LEVEL, A
    NIOSH-APPROVED ORGANIC VAPOR RESPIRATOR SHOULD BE WORN.
Ventilation:MECHANICAL (GENERAL AND/OR LOCAL EXHAUST, EXPLOSION-PROOF)
    VENTILATION TO MAINTAIN EXPOSURE BELOW TLV(S).
Protective Gloves:BUTYL OR PVA
Eye Protection:SAFETY GLASSES - CHEMICAL SPLASH GOGGLES
Other Protective Equipment:EYE WASH STATION AND SAFETY SHOWER.
    INDUSTRIAL-TYPE WORK CLOTHING AND APRON AS REQUIRED.
Work Hygienic Practices:OBSERVE GOOD INDUSTRIAL HYGIENE PRACTICES AND
    RECOMMENDED PROCEDURES. WASH THOROUGHLY BEFORE EATING,
    DRINKING/SMOKING.
Supplemental Safety and Health
AVOID PROLONGED OR REPEATED EXPOSURE. DO NOT GET ON SKIN OR IN EYES. DO
    NOT BREATHE VAPORS. DO NOT INGEST. READ PRECAUTIONS ON LABEL BEFORE
    USE.
