Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    irritation, nausea, difficulty breathing, headache, drowsiness,
    symptoms of drunkenness LONG TERM EXPOSURE: tingling sensation,
    nerve damage SKIN CONTACT: SHORT TERM EXPOSURE: irritation,
    blisters, itching LONG TERM EXPOSURE: same as effects reported in
    short term exposure EYE CONTACT: SHORT TERM EXPOSURE: no
    information on significant adverse effects LONG TERM EXPOSURE: no
    information on significant adverse effects INGESTION: SHORT TERM
    EXPOSURE: nausea, stomach pain, symptoms of drunkenness, lung
    congestion, brain damage 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: If a large amount
    is swallowed, get medical attention.


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

Flash Point:<-40 F (<-40 C) (CC)
Autoignition Temp:500 F (260 C)
Lower Limits:1.4%
Upper Limits:7.8%
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).
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. Electrostatic
    discharges may be generated by flow or agitation resulting in
    ignition or explosion.

==================  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. Small spills: Absorb with sand or other
    non-combustible material. Collect spilled material in appropriate
    container for disposal. Large spills: Dike for later disposal.
    Remove sources of ignition. Keep unnecessary people away, isolate
    hazard area and deny entry.
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. See original container for storage recommendations. 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. 1200 ppm Any
    supplied-air respirator. 1500 ppm Any supplied-air respirator. 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. 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.
Ventilation:Ventilation equipment should be explosion-resistant if
    explosive concentrations of material are present. Provide local
    exhaust ventilation system. 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.
