Fraction by Wt: >99.5%

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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    nausea, vomiting, diarrhea, headache, drowsiness, symptoms of
    drunkenness, visual disturbances, bluish skin color, lung
    congestion, nerve damage, paralysis, convulsions, coma LONG TERM
    EXPOSURE: fainting, blurred vision SKIN CONTACT: SHORT TERM

    damage LONG TERM EXPOSURE: same as effects reported in long term
    inhalation EYE CONTACT: SHORT TERM EXPOSURE: frostbite LONG TERM
    EXPOSURE: no information is available INGESTION: SHORT TERM
    EXPOSURE: frostbite 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:
    If frostbite or freezing occur, immediately flush with plenty of
    lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm
    water is not available, gently wrap affected parts in blankets. Get
    immediate medical attention. EYE CONTACT: Wash eyes immediately
    with large amounts of water, occasionally lifting upper and lower
    lids, until no evidence of chemical remains. Get medical attention
    immediately. INGESTION: Never make an unconscious person vomit or
    drink fluids. Give large amounts of water. DO NOT induce vomiting.
    If 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.

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

Flash Point:<32.0 F (<0 C) (CC)
Autoignition Temp:1170 F (632 C)
Lower Limits:8.1%
Upper Limits:17.4%
Extinguishing Media:Let burn unless leak can be stopped immediately.
    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). Stop flow of gas.
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. Gas/air mixtures are explosive.

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

Neutralizing Agent:

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Protect from physical
    damage. Store in a cool, dry place. Store in a well-ventilated
    area. Avoid heat, flames, sparks and other sources of ignition.
    Store outside or in a detached building. Subject to storage
    regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
    required. Keep separated from incompatible substances.
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 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 insulated 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.
