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

LD50 LC50 Mixture:LD5O (ORAL-RAT) > 5 G/KG
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:YES
Health Hazards Acute and Chronic:EYE IRRITATION, SKIN IRRITATION,
    RESPIRATORY IRRITATION, CENTRAL NERVOUS SYSTEM DISTURBANCES,
    GASTROINTESTINAL IRRITATION, ASPIRATION HAZARD.
Explanation of Carcinogenicity:PRODUCT CONTAINS BENZENE
Effects of Overexposure:SLIGHT TO MODERATE EYE IRRITATION,
    REDNESS/EDEMA/DRYING OF THE SKIN, DIZZINESS, HEADACHE, NAUSEA,
    STUPOR, VOMITING, PNUEMONITITS, PULMONARY EDEMA.
Medical Cond Aggravated by Exposure:PRE-EXISTING SKIN AND OR
    RESPIRATORY CONDITIONS MAY BE AGGRAVATED BY EXPOSURE.

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

First Aid:EYES: FLUSH WITH WATER FOR 15 MINUTES. IF IRRITATION PERSIST,
    SEEK MEDICAL ATTENTION. SKIN: REMOVE CONTAMINATED CLOTHING.
    THOROUGHLY WASH AFFECTED AREA WITH SOAP AND WATER. INHALATION:
    IMMEDIATELY REM OVE TO FRESH AIR. IN CASE OF RESPIRATORY DISTRESS,
    GIVE OXYGEN OR ARTIFICIAL RESPIRATION. INGESTION: DO NOT INDUCE
    VOMITING. IF VOMITING OCCURS, KEEP HEAD BELOW HIPS TO PREVENT
    ASPIRATION INTO LUNGS.

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

Flash Point Method:COC
Flash Point:-40F,-40C
Autoignition Temp:Autoignition Temp Text:850F
Lower Limits:1.4%
Upper Limits:7.6%
Extinguishing Media:DRY CHEMICAL, FOAM OR CARBON DIOXIDE. WATER MAY BE
    INEFFECTIVE ON FLAMES, BUT SHOULD BE USED TO COOL CONTAINERS.
Fire Fighting Procedures:IF A LEAK OR SPILL HAS NOT IGNITED, USE WATER
    SPRAY TO DISPERSE THE VAPORS AND TO PROVIDE PROTECTION FOR THE
    PERSONS ATTEMPTING TO STOP THE LEAK.
Unusual Fire/Explosion Hazard:FLOWING GASOLINE CAN BE IGNITED BY
    SELF-GENERATED STATIC ELECTRICITY; USE ADEQUATE GROUNDING. VAPORS
    ENTERING SEWERS OR OTHER CONFINED SPACES MAY CREATE HAZARD.

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

Spill Release Procedures:ELIMINATE ALL IGNITION SOURCES INCLUDING
    INTERNAL COMBUSTION ENGINES AND POWER TOOLS. VENTILATE AREA. AVOID
    BREATHING VAPOR. USE SCBA OR SUPPLIED-AIR MASK FOR LARGE SPILLS IN
    CONFINED AREAS. CONTAIN S PILL IF POSSIBLE. REMOVE WITH INERT
    ABSORBENT.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:KEEP AWAY FORM HEAT, SPARKS AND
    FLAMES. AVOID BREATHING VAPOR. USE ONLY IN WELL-VENTILATED
    LOCATIONS. AVOID CONTACT W/EYES & PROLONGED CONTACT W/SKIN.
Other Precautions:LONG TERM EXPOSURE TO VAPORS HAS CAUSED CANCER IN
    LABORATORY ANIMALS. TRANSPORT, HANDLE AND STORE IN ACCORDANCE WITH
    OSHA REGULATION 1910.106 AND APPLICABLE DOT REGULATIONS.

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

Respiratory Protection:NONE NECESSARY UNDER NORMAL CONDITIONS WITH
    ADEQUATE VENTILATION. IF CONCENTRATIONS EXCEED THE PEL, NIOSH
    APPROVED RESPIRATORY PROTECTION MUST BE WORN. THIS INCLUDES BOTN
    AIR PURIFYING CARTRIDGE RESPI RATORS OR AIR-SUPPLIED RESPIRATORS.
Ventilation:USE ADEQUATE NATURAL OR MECHANICAL VENTILATION TO KEEP
    VAPOR CONCENTRATIONS OF THIS MATERIAL AT/OR BELOW THE PEL.
Protective Gloves:CHEMICAL RESISTANT
Eye Protection:CHEMICAL TYPE GOGGLES OR FACE SHIELD
Other Protective Equipment:PROTECTIVE CLOTHING SUCH AS UNIFORMS,
    COVERALLS OR LAB COATS SHOULD BE WORN. LAUNDER OR DRY CLEAN WHEN
    SOILED.
Work Hygienic Practices:WASH WITH SOAP AND WATER AFTER HANDLING PRODUCT
    AND BEFORE EATING DRINKING OR SMOKING.
Supplemental Safety and Health
RECENT STUDIES WITH LABORATORY ANIMALS HAVE SHOWN THAT GASOLINE VAPORS
    ADMINISTERED IN HIGH CONCENTRATIONS OVER PROLONGED PERIOD OF TIME
    CAUSED KIDNEY DAMAGE AND KIDNEY CANCER IN MALE RATS AND LIVER C
    ONCER IN FEMALE MICE. GENERALLY HUMAN EXPOSURE IS CONSIDERABLY LESS
    THAN THOSE USED IN ANIMAL TOXICITY STUDIES.
