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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    irritation, difficulty breathing, headache, drowsiness, symptoms of
    drunkenness, blurred vision LONG TERM EXPOSURE: no information on
    significant adverse effects SKIN CONTACT: SHORT TERM EXPOSURE:
    irritation (possibly severe) LONG TERM EXPOSURE: no information is
    available EYE CONTACT: SHORT TERM EXPOSURE: irritation (possibly
    severe) LONG TERM EXPOSURE: no information is available INGESTION:
    SHORT TERM EXPOSURE: no information on significant adverse effects
    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: Immediately 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:-42 F (-41 C) (CC)
Autoignition Temp:662 F (350 C)
Lower Limits:3.4%
Upper Limits:27.0%
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
    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: Stop leak if possible without
    personal risk. Let burn unless leak can be stopped immediately. For
    smaller tanks or cylinders, extinguish and isolate from other
    flammables. Evacuation radius: 800 meters (1/2 mile).
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
    are explosive. Containers may rupture or explode if exposed to
    heat. The vapor is heavier than air. Vapors or gases may ignite at
    distant ignition sources and flash back. Electrostatic discharges
    may be generated by flow or agitation resulting in ignition or
    explosion. Severe explosion hazard.

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

Spill Release Procedures:Avoid heat, flames, sparks and other sources
    of ignition. Do not touch spilled material. 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.
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. Keep separated from incompatible substances. Protect from
    physical damage. Store outside or in a detached building. Inside
    storage: Store in a cool, dry place. Store in a well-ventilated
    area. Avoid heat, flames, sparks and other sources of ignition.
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 chemical cartridge 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. 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 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:For the gas: Protective clothing is not
    required. For the liquid: Wear appropriate protective, cold
    insulating clothing.
