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: Contact local poison
    control center or physician immediately. Never make an unconscious
    person vomit or drink fluids. Give large amounts of water or milk.
    Allow vomiting to occur. 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.   Avoid gastric lavage or emesis.

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

Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
    Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Do not get water inside container. 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. Keep unnecessary people away, isolate
    hazard area and deny entry. Use extinguishing agents appropriate
    for surrounding fire. Flood with fine water spray. Cool containers
    with water spray until well after the fire is out. Apply water from
    a protected location or from a safe distance. Avoid inhalation of
    material or combustion by-products. Stay upwind and keep out of low
    areas. Consider downwind evacuation if material is leaking.
Unusual Fire/Explosion Hazard:Negligible fire hazard.

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

Spill Release Procedures:Stop leak if possible without personal risk.
    Reduce vapors with water spray. Do not get water directly on
    material. Do not get water inside container. Keep unnecessary
    people away, isolate hazard area and deny entry. Small spills:
    Flood with water. Large spills: Dike for later disposal. Stay
    upwind and keep out of low areas. Ventilate closed spaces before
    entering. Evacuation radius: 150 feet.
Neutralizing Agent:

======================	Handling and Storage  ======================

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Keep separated from
    incompatible substances.
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 chemical cartridge respirator
    with acid gas cartridge(s). Any chemical cartridge respirator with
    a full facepiece and acid gas cartridge(s). Any air-purifying
    respirator with a full facepiece and an acid gas canister. 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. 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.
