*  Exposure Controls/Personal Protection  *
Respiratory Protection:The following respirators and maximum use
    chemical cartridge respirator with organic vapor cartridge(s). Any
    powered, air-purifying respirator with organic vapor cartridge(s).
    Any supplied-air respirator. Any self-contained breathing apparatus
    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.
    emergency eye wash fountain and quick drench shower in the
    immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.

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:
    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
    Contact local poison control center or physician immediately. Never
    make an unconscious person vomit or drink fluids. When 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.  
    For ingestion, consider gastric lavage.
*  Fire Fighting Measures  *
Lower Limits:1.1%
Upper Limits:7.0%
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.
    (1/2 mile). Water may be ineffective.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
    are explosive above flash point. 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.
