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:-130 F (-90 C) (CC)
Autoignition Temp:100-126 F (38-52 C)
Lower Limits:0.8%
Upper Limits:88%
Extinguishing Media:Let burn unless leak can be stopped immediately.
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). Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Gas/air mixtures are
    explosive.

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

Spill Release Procedures:Avoid heat, flames, sparks and other sources
    of ignition. Stop leak if possible without personal risk. Reduce
    vapors with water spray. Keep unnecessary people away, isolate
    hazard area and deny entry. Remove sources of ignition. Ventilate
    closed spaces before entering. Notify Local Emergency Planning
    Committee and State Emergency Response Commission for release
    greater than or equal to RQ (U.S. SARA Section 304). If release
    occurs in the U.S. and is reportable under CERCLA Section 103,
    notify the National Response Center at (800)424-8802 (USA) or
    (202)426-2675 (USA).

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Protect from physical
    damage. Store and handle in a detached building. Refrigerate. Store
    in a well-ventilated area. Avoid contact with air. Keep separated
    from incompatible substances. Store under an inert atmosphere. 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. 1 ppm Any
    supplied-air respirator. 2.5 ppm Any supplied-air respirator. 5 ppm
    Any supplied-air respirator with a full facepiece. Any
    self-contained breathing apparatus with a full facepiece. Any
    supplied-air respirator with a full facepiece. 15 ppm Any
    supplied-air respirator operated in a pressure-demand or other
    positive-pressure mode. 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. Provide an
    emergency eye wash fountain and quick drench shower in the
    immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.
