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.
Unusual Fire/Explosion Hazard:Negligible fire hazard. Containers may
    rupture or explode if exposed to heat.

==================  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.

    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 or process enclosure 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.
