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 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 ingestion, consider gastric
    lavage. Consider oxygen.

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

Flash Point:174 F (79 C) (CC)
Autoignition Temp:979 F (526 C)
Lower Limits:0.9%
Upper Limits:5.9%
Extinguishing Media:regular dry chemical, dry sand, earth, regular
    foam, water 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.
Unusual Fire/Explosion Hazard:Moderate fire hazard. Dust/air mixtures
    may ignite or explode.

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

Spill Release Procedures:Avoid heat, flames, sparks and other sources
    of ignition. Do not touch spilled material. Small spills: Collect
    spilled material in appropriate container for disposal. Move
    containers away from spill to a safe area. Large spills: Wet down
    area with water. 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. Store in a cool, dry place.
    Store in a well-ventilated area. Keep separated from incompatible
    substances. Store under an inert atmosphere. 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. 100 ppm Any
    chemical cartridge respirator with organic vapor cartridge(s) and
    dust and mist filter(s). Any supplied-air respirator. 250 ppm Any
    supplied-air respirator. Any chemical cartridge respirator with a
    full facepiece, organic vapor cartridge(s) and high-efficiency
    particulate filter(s). Any powered, air-purifying respirator with
    organic vapor cartridge(s) and dust and mist filter(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, an organic vapor
    canister and high-efficiency particulate filter. 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 with a faceshield.
    Provide an emergency eye wash fountain and quick drench shower in
    the immediate work area.
