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 a large amount is swallowed, get medical attention. NOTE TO
    PHYSICIAN: For inhalation, consider oxygen.

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

Flash Point:-63 F (-53 C) (SCC)
Autoignition Temp:743 F (395 C)
Lower Limits:1.5%
Upper Limits:8.9%
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). Water may be ineffective. 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. Avoiinhalation of material or combustion
    by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
    are explosive. The vapor is heavier than air. Vapors or gases may
    ignite at distant ignition sources and flash back.

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

Neutralizing Agent:

======================	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. Store in a cool, dry place. Store in a well-ventilated
    area. Store outside or in a detached building. Keep separated from
    incompatible substances.
Other Precautions:

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

Respiratory Protection:Under conditions of frequent use or heavy
    exposure, respiratory protection may be needed. Respiratory
    protection is ranked in order from minimum to maximum. Consider
    warning properties before use. Any supplied-air respirator with a
    full facepiece that is operated in a pressure-demand or other
    positive-pressure mode. Any self-contained breathing apparatus that
    has a full facepiece and is operated in a pressure-demand or other
    positive-pressure mode. 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.
