    irritation, tearing, vomiting, diarrhea, difficulty breathing,
    headache, drowsiness, symptoms of drunkenness LONG TERM EXPOSURE:
    lung congestion, cancer SKIN CONTACT: SHORT TERM EXPOSURE:
    irritation (possibly severe), blisters LONG TERM EXPOSURE: same as
    effects reported in short term exposure EYE CONTACT: SHORT TERM

    effects reported in short term exposure INGESTION: SHORT TERM
    EXPOSURE: no information on significant adverse effects LONG TERM
    EXPOSURE: cancer
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 immediate medical
    attention. Thoroughly clean and dry contaminated clothing and shoes
    before reuse. Destroy contaminated shoes. EYE CONTACT: Immediately
    flush eyes with plenty of water for at least 15 minutes. Then get
    immediate medical attention. INGESTION: Contact local poison
    control center or physician immediately. Never make an unconscious
    person vomit or drink fluids. When vomiting occurs, keep head lower
    than hips to help prevent aspiration. If person is unconscious,
    turn head to side. Get medical attention immediately. NOTE TO
    PHYSICIAN: For inhalation, consider oxygen.   For ingestion,
    consider gastric lavage and activated charcoal slurry.

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

Flash Point:-35 F (-37 C) (CC)
Autoignition Temp:840 F (449 C)
Lower Limits:2.3%
Upper Limits:36%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
    chemical, water, alcohol resistant foam Large fires: Use
    alcohol-resistant foam or flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
    done without risk. Cool containers with water spray until well
    after the fire is out. Stay away from the ends of tanks. For fires
    in cargo or storage area: Cool containers with water from unmanned
    hose holder or monitor nozzles until well after fire is out. If
    this is impossible then take the following precautions: Keep
    unnecessary people away, isolate hazard area and deny entry. Let
    the fire burn. Withdraw immediately in case of rising sound from
    venting safety device or any discoloration of tanks due to fire.
    For tank, rail car or tank truck: Evacuation radius: 800 meters
    (1/2 mile). Water may be ineffective.
Unusual Fire/Explosion Hazard:Moderate fire hazard. The vapor is
    heavier than air. Vapors or gases may ignite at distant ignition
    sources and flash back. Vapor/air mixtures are explosive above
    flash point.

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

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Subject to storage
    regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
    required. Protect from physical damage. Store outside or in a
    detached building. Store with flammable liquids. Keep separated
    from incompatible substances. Keep separated from incompatible
    substances. Notify State Emergency Response Commission for storage
    or use at amounts greater than or equal to the TPQ (U.S. EPA SARA
    Section 302). SARA Section 303 requires facilities storing a
    material with a TPQ to participate in local emergency response
    planning (U.S. EPA 40 CFR 355.30).
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 a canister providing protection against this substance. 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. Ventilation equipment should be explosion-resistant if
    explosive concentrations of material are present. 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.
