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

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

Flash Point:14 F (-10 C) (CC)
Autoignition Temp:849 F (454 C)
Lower Limits:3.1%
Upper Limits:16%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
    chemical, water, alcohol resistant foam 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. 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. Moderate explosion
    hazard. The vapor is heavier than air. Vapors or gases may ignite
    at distant ignition sources and flash back. Vapor/air mixtures are
    explosive above flash point.

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

Spill Release Procedures:Avoid heat, flames, sparks and other sources
    of ignition. Remove 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. Keep unnecessary people away,
    isolate hazard area and deny entry. Stay upwind and keep out of low
    areas.
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.
Other Precautions:

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

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. 2000 ppm Any
    chemical cartridge respirator with organic vapor cartridge(s). Any
    supplied-air respirator. 3100 ppm Any supplied-air respirator. Any
    chemical cartridge respirator with a full facepiece and organic
    vapor cartridge(s). Any air-purifying respirator with a full
    facepiece, an organic vapor and acid gas canister. Any powered,
    air-purifying respirator with organic vapor cartridge(s). 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: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 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.
