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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    irritation (possibly severe), nausea, vomiting, difficulty
    breathing, headache, symptoms of drunkenness, fainting, bluish skin
    color, lung congestion, coma, death LONG TERM EXPOSURE: digestive
    disorders SKIN CONTACT: SHORT TERM EXPOSURE: irritation (possibly
    severe), nausea, vomiting, difficulty breathing, headache, symptoms
    of drunkenness, fainting, coma LONG TERM EXPOSURE: same as effects
    reported in short term exposure EYE CONTACT: SHORT TERM EXPOSURE:
    irritation (possibly severe) LONG TERM EXPOSURE: same as effects
    reported in short term exposure INGESTION: SHORT TERM EXPOSURE:
    burns, death LONG TERM EXPOSURE: same as effects reported in short
    term exposure
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 immediate medical
    attention. Thoroughly clean and dry contaminated clothing and shoes
    before reuse. Destroy contaminated shoes. EYE CONTACT: Immediately
    flush eyes with plenty of water for at least 15 minutes. Then get
    immediate medical attention. INGESTION: If swallowed, drink plenty
    of water, do NOT induce vomiting. Get immediate medical attention.
    NOTE TO PHYSICIAN: For inhalation, consider oxygen.   For
    ingestion, consider gastric lavage.

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

Flash Point:19 F (-7 C) (CC)
Autoignition Temp:916 F (491 C)
Lower Limits:2.1%
Upper Limits:15.6%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
    chemical, water Large fires: Use alcohol-resistant foam or flood
    with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
    done without risk. Dike for later disposal. Do not scatter spilled
    material with high-pressure water streams. Cool containers with
    water spray until well after the fire is out. Stay away from the
    ends of tanks. 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.
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.

==================  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. 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. 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. Subject to storage
    regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
    required. Keep separated from incompatible substances. Store in a
    tightly closed container. Containers must have overpressure release
    device. Avoid heat, flames, sparks and other sources of ignition.
    Keep separated from incompatible substances. Monitor inhibitor
    content. Avoid exposure to low temperatures or freezing. Protect
    from physical damage. Store outside or in a detached building.
    Inside storage: Store with flammable liquids. Quarterly maintenance
    of ventilation systems is required. 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: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. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant 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.
