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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    irritation, nausea, difficulty breathing, headache, symptoms of
    drunkenness LONG TERM EXPOSURE: no information on significant
    adverse effects SKIN CONTACT: SHORT TERM EXPOSURE: irritation,
    blisters, symptoms of drunkenness LONG TERM EXPOSURE: rash, itching

    INGESTION: SHORT TERM EXPOSURE: vomiting, stomach pain, symptoms of
    drunkenness, lung congestion LONG TERM EXPOSURE: no information on
    significant adverse effects
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.
    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: 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 ingestion, consider gastric lavage.

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

Flash Point:97 F (36 C) (CC)
Autoignition Temp:795 F (424 C)
Lower Limits:0.9%
Upper Limits:6.5%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
    regular foam 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. 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). Do not attempt to extinguish fire unless flow of
    material can be stopped first. Flood with fine water spray. Do not
    scatter spilled material with high-pressure water streams. 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 ocombustion by-products. Stay upwind and
    keep out of low areas.
Unusual Fire/Explosion Hazard:Severe 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.
    Electrostatic discharges may be generated by flow or agitation
    resulting in ignition or explosion.

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

Spill Release Procedures:[Spills may need to be reported to the
    National Response Center (800/424-8802) CERCLA Reportable Quantity
    (RQ) is 1000 pounds]. Shut off and eliminate all ignition sources.
    Keep people away. Recover by pumping (use an explosion proof or
    hand pump) or with a suitable absorbent such as sand, earth or
    other suitable absorbent to spill area. Do not use combustible
    materials such as sawdust. Minimize breathing vapors. Minimize skin
    contact. Ventilate confined spaces. Open all windows and doors.
    Keep product out of sewers and watercourses by diking or
    impounding. Advise authorities if product has entered or may enter
    sewers, watercourses, or extensive land areas.
Neutralizing Agent:

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

Handling and Storage Precautions:Keep away from heat, sparks and open
    flames. Keep containers tightly closed. Store away from strong
    oxidizing agents in a cool, dry place with adequate explosion-proof
    ventilation. Ground equipment to prevent accumulation of static
    charge. If pouring or transferring materials, containers must be
    bonded and grounded.
Other Precautions:Do Not weld, heat or drill on or near container; even
    emptied containers can contain explosive vapors.

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

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. 500 ppm Any
    chemical cartridge respirator with organic vapor cartridge(s). Any
    supplied-air respirator. 900 ppm Any supplied-air respirator. Any
    powered, air-purifying respirator with organic vapor cartridge(s).
    Any chemical cartridge respirator with a full facepiece and organic
    vapor cartridge(s). Any air-purifying respirator with a full
    facepiece and an organic vapor canister. Any self-contained
    breathing apparatus with a full facepiece. Any supplied-air
    respirator with a full facepiece. 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. 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. Provide an
    emergency eye wash fountain and quick drench shower in the
    immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.
