    irritation, nausea, vomiting, diarrhea, headache, drowsiness,
    symptoms of drunkenness, blurred vision, lung congestion,
    convulsions, coma, death LONG TERM EXPOSURE: visual disturbances
    SKIN CONTACT: SHORT TERM EXPOSURE: irritation, blisters, rash,

    SHORT TERM EXPOSURE: irritation (possibly severe) LONG TERM
    EXPOSURE: same as effects reported in short term exposure
    INGESTION: SHORT TERM EXPOSURE: vomiting, digestive disorders,
    symptoms of drunkenness LONG TERM EXPOSURE: no information is
    available
Medical Cond Aggravated by Exposure:

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

First Aid: INHALATION: If adverse effects occur, remove to
    uncontaminated area. Give artificial respiration if not breathing.
    If breathing is difficult, oxygen should be administered by
    qualified personnel. Get immediate medical attention. SKIN CONTACT:
    Wash skin with soap and water for at least 15 minutes while
    removing contaminated clothing and shoes. Get medical attention, if
    needed. Thoroughly clean and dry contaminated clothing and shoes
    before reuse. EYE CONTACT: Flush eyes with plenty of water for at
    least 15 minutes. Then get immediate medical attention. INGESTION:
    If swallowed, drink plenty of water, do NOT induce vomiting. Get
    immediate medical attention. Induce vomiting only at the
    instructions of a physician. Do not give anything by mouth to
    unconscious or convulsive person. NOTE TO PHYSICIAN: For
    inhalation, consider oxygen.   For ingestion, consider gastric
    lavage, activated charcoal slurry and catharsis.

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

Flash Point:No data available.
Extinguishing Media:regular dry chemical, regular foam, water Large
    fires: Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
    done without risk. Fight large fires from a protected location or
    safe distance. Stay away from the ends of tanks. Dike for later
    disposal. Do not scatter spilled material with high-pressure water
    streams. Do not attempt to extinguish fire unless flow of material
    can be stopped first. Use extinguishing agents appropriate for
    surrounding fire. Flood with fine water spray. Cool containers with
    water spray until well after the fire is out. Apply water from a
    protected location or from a safe distance. Avoid inhalation of
    material or combustion by-products. Stay upwind and keep out of low
    areas. Consider downwind evacuation if material is leaking.
Unusual Fire/Explosion Hazard:Negligible fire hazard.

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Keep separated from
    incompatible substances. Store in a tightly closed container. Avoid

Other Precautions:

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

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. At any detectable
    concentration - Any self-contained breathing apparatus that has a
    full facepiece and is operated in a pressure-demand or other
    positive-pressure mode. Any supplied-air respirator with full
    facepiece and operated in a pressure-demand or other
    positive-pressure mode in combination with a separate escape
    supply. Escape - Any air-purifying respirator with a full facepiece
    and an organic vapor canister. Any appropriate escape-type,
    self-contained breathing apparatus. For Unknown Concentrations or
    Immediately Dangerous to Life or Health - Any supplied-air
    respirator with full facepiece and operated in a pressure-demand or
    other positive-pressure mode in combination with a separate escape
    supply. Any self-contained breathing apparatus with a full
    facepiece.
Ventilation:Provide local exhaust or process enclosure ventilation
    system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
    Provide an emergency eye wash fountain and quick drench shower in
    the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.
