    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 person is
    unconscious, turn head to side. Never make an unconscious person
    vomit or drink fluids. When vomiting occurs, keep head lower than
    hips to help prevent aspiration. Contact local poison control
    center or physician immediately. Get medical attention. NOTE TO
    PHYSICIAN: For ingestion, consider gastric lavage and activated
    charcoal slurry.

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

Flash Point:-8 F (-22 C) (CC)
Autoignition Temp:437 F (225 C)
Lower Limits:1.1%
Upper Limits:7.5%
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). 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. 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. 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.
Other Precautions:

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. 500 ppm Any
    supplied-air respirator. 1100 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.
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 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.
