Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION CAUSES IRRITATION TO
    RESPIRATORY TRACT. INGESTION: MAY CAUSE TIGHTNESS OF MUSCLES OF
    FACE AND NECK . MAY CAUSE KIDNEY DAMAGE.  SKIN/EYE CONTACT CAUSES
    IRRITATION. REPEATED CONTACT WITH LIQU ID MAY CAUSE DRYNESS,
    CRACKING, SKIN IRRITATION. CAUSES EYE IRRITATION. AFFECTS THE
    CENTRAL NERVOUS SYSTEM. CHRONIC EFFECTS MAY BE SIMILAR TO THOSE
    FROM METHANOL EXPOSURE BECAUSE METHYL ACETATE CAN BE  HYDROLYZED
    YIELDING METHANOL AND ACETIC ACID. OPTIC NERVE DAMAGE IS THE
    PREDOMINANT HAZARD.
Explanation of Carcinogenicity:THIS COMPOUND CONTAINS NO INGREDIENTS AT
    CONCENTRATIONS OF 0.1% OR GREATER THAT ARE CARCINOGENS OR SUSPECT
    CARCINOGENS.
Effects of Overexposure:COUGHING, SHORTNESS OF BREATH, TIGHTNESS OF
    MUSCLES OF FACE AND NECK, VOMITING, DIARRHEA, ABDOMINAL PAIN,
    MUSCULAR TREMORS, ANXIETY, WEAKNESS, LABORED BREATHING, CARDIAC
    IRREGULARITY, CONVULSIONS, DEA TH FROM CARDIAC AND RESPIRATORY
    FAILURE, SKIN IRRITATION, ITCHING, PAIN, EYE IRRITATION, REDNESS,
    PAIN. MAY CAUSE KIDNEY DAMAGE.
Medical Cond Aggravated by Exposure:PERSONS WITH PRE-EXISTING SKIN AND
    NERVOUS SYSTEM DISORDERS OR IMPAIRED RESPIRATORY OR KIDNEY FUNCTION
    MAY BE MORE SUSCEPTIBLE TO THE EFFECTS OF THIS SUBSTANCE.

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

First Aid:EYES: IMMEDIATELY FLUSH WITH WATER FOR AT LEAST 15 MINUTES,
    LIFTING UPPER AND LOWER EYELIDS OCCASIONALLY. GET MEDICAL
    ATTENTION. SKIN: FLUSH WITH WATER FOR AT LEAST 15 MINUTES. REMOVE
    CLOTHING AND SHO ES. GET MEDICAL ATTENTION. INHALATION: REMOVE TO
    FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION. IF
    BREATHING IS DIFFICULT, GIVE OXYGEN. GET MEDICAL HELP. INGESTION:
    GET MEDICAL ATTENTION IM MEDIATELY. INDUCE VOMITING AS DIRECTED BY
    MEDICAL PERSONNEL. NEVER GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS
    PERSON. SEE NEUTRALIZING AGENT.

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

Flash Point:NONE
Lower Limits:NOT GIVEN
Upper Limits:NOT GIVEN
Extinguishing Media:FOAM, DRY CHEMICAL, CARBON DIOXIDE, FLOODING
    AMOUNTS OF WATER IN EARLY STAGES OF FIRE. DO NOT USE WATER ON
    MOLTEN MATERIAL.
Fire Fighting Procedures:WEAR FULL PROTECTIVE CLOTHING AND
    NIOSH-APPROVED SELF-CONTAINED BREATHING APPARATUS WITH FULL
    FACEPIECE OPERATED IN THE PRESSURE DEMAND OR OTHER POSITIVE
    PRESSURE MODE.
Unusual Fire/Explosion Hazard:DO NOT RELEASE RUNOFF FROM FIRE CONTROL
    METHODS TO SEWERS OR WATERWAYS. STRONG OXIDIZER AND ITS HEAT OF
    REACTION WITH REDUCING AGENTS/COMBUSTIBLES MAY IGNITE. CONTACT WITH
    OXIDIZABLE SUBSTANCES MAY CA USE EXTREMELY VIOLENT COMBUSTION.
    EMITS NITROGEN OXIDES WHEN HEATED TO DECOMPOSITION.

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

    PERSONAL PROTECTIVE EQUIPMENT.  PICK UP AND PLACE IN A SUITABLE
    CONTAINER FOR RECLAMATION OR  DISPOSAL, USING A METHOD THAT DOES
    NOT GENERATE DUST.
Neutralizing Agent:AFTER VOMITING, A MIXTURE OF 1 TABLESPOON OF SODIUM
    OR MAGNESIUM SULFATE(EPSOM SALTS) DISSOLVED IN 8 OZ OF WATER

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

Handling and Storage Precautions:KEEP IN TIGHTLY CLOSED CONTAINER,
    STORED IN A COOL, DRY, VENTILATED AREA. PROTECT AGAINST PHYSICAL
    DAMAGE. ISOLATE FROM INCOMPATIBLES.
Other Precautions:SEPARATE FROM COMBUSTIBLES, ORGANIC OR OTHER READILY
