=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Explanation of Carcinogenicity:NONE
Effects of Overexposure:INHALATION: IRRITATE RESPIRATORY TRACT.  CAUSES
    CENTRAL NERVOUS SYSTEM EFFECTS.  LIGHTHEADEDNESS, DIZZINESS,
    NAUSEA, HEADACHE.  INGESTION: NAUSEA, VOMITING.  LARYNGEAL, OCULAR,
    AND RESPIRATORY MUSCLES  ARE AFFECTED IN SEVERE POISONING.	SKIN: A
    MILD SKIN IRRITANT WHICH CAUSES LOSS OF NATURAL OILS.  EYE: VAPORS
    CAN IRRITATE EYES; SPLASHES MAY CAUSE DAMAGE TO EYE TISSUE.
Medical Cond Aggravated by Exposure:PERSONS WITH PRE-EXISTING SKIN
    DISORDERS OR EYE PROBLEMS OR IMPAIRED RESPIRATORY FUNCTION MAY BE
    MORE SUSCEPTIBLE TO THE EFFECTS OF THE SUBSTANCE.

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

First Aid:INGESTION: INDUCE VOMITING IMMEDIATELY AS DIRECTED BY
    PERSONNEL.	NEVER GIVE ANYTHING BY MOUTH.  INHALATION: REMOVE TO
    FRESH AIR. IF BREATHING STOPS, GIVE ARTIFICIAL RESPIRATION. IF
    BREATHING IS DIFFI CULT, GIVE OXYGEN. SKIN/EYES: FLUSH W/PLENTY OF
    WATER FOR AT LEAST 15 MINS. OBTAIN MEDICAL ATTENTION IN ALL CASES.

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

Flash Point:=-27.2C, -17.F
Autoignition Temp:=435.C, 815.F
Lower Limits:1.6
Upper Limits:8.4
Extinguishing Media:WATER SPRAY, DRY CHEMICAL, ALCOHOL FOAM, OR CARBON
    DIOXIDE.  WATER SPRAY MAY BE USED TO KEEP FIRE EXPOSED CONTAINERS
    COOL.
Fire Fighting Procedures:WATER MAY BE INEFFECTIVE. WEAR PROTECTIVE
    EQUIPMENT & SELF-CONTAINED BREATHING APPARATUS OPERATED IN POSITIVE
    PRESSURE MODE. MOVE CONTAINERS FROM FIRE AREA.
Unusual Fire/Explosion Hazard:ABOVE THE FLASH POINT, EXPLOSIVE
    VAPOR-AIR MIXTURES MAY BE FORMED.  VAPORS CAN FLOW ALONG SURFACES
    TO DISTANT IGNITION SOURCE ADN FLASH BACK.	SEALED CONTAINERS MAY
    RUPTURE WHEN HEATED.  SENSITIVE TO	STATIC DISCHARGE.

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

Spill Release Procedures:VENTILATE AREA OF LEAK OR SPILL.  REMOVE ALL
    SOURCES OF IGNITION.  WEAR APPROPRIATE PERSONAL PROTECTIVE
    EQUIPMENT AS SPECIFIED IN SEC 8.  ISOLATE HAZARD AREA.  KEEP
    UNNECESSARY AND UNPROTECTED PERSONN EL FROM ENTERING.  CONTAIN AND
    RECOVER LIQUID WHEN POSSIBLE.  USE NON-SPARKING TOOLS AND
    EQUIPMENT.	COLLECT LIQUID IN AN APPROPRIATE CONTAINER OR ABSORB
    WITH AN INERT MATERIAL.

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

Handling and Storage Precautions:PROTECT AGAINST PHYSICAL DAMAGE. 
    STORE IN A COOL, DRY WELL-VENTILATED LOCATION, AWAY FROM ANY AREA
    WHERE THE FIRE HAZARD MAY BE ACUTE.  OUTSIDE OR DETACHED STORAGE IS
    PREFERRED.	SEPARATE FROM INCOMP ATIBLES.  CONTAINERS SHOULD BE
    BONDED AND GROUNDED FOR TRANSFERS TO AVOID STATIC SPARKS.
Other Precautions:WARNING!  EXTREMELY FLAMMABLE LIQUID AND VAPOR. 
    VAPOR MAY CAUSE FLASH FIRE.  HARMFUL IF SWALLOWED, INHALED OR
    ABSORBED THROUGH SKIN.  MAY AFFECT CENTRAL NERVOUS SYSTEM, BLOOD,
    AND KIDNEYS.  A CENTRAL  NERVOUS SYSTEM DEPRESSANT.  CAUSES
    IRRITATION TO SKIN, EYES, AND RESPIRATORY TRACT.
