=======================  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 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 inhalation,
    consider oxygen.   For ingestion, consider gastric lavage. Consider
    oxygen.

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

Flash Point:No data available.
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. Do not scatter spilled material with
    high-pressure water streams. Dike for later disposal. Use
    extinguishing agents appropriate for surrounding fire. Avoid
    inhalation of material or combustion by-products. Stay upwind and
    keep out of low areas.
Unusual Fire/Explosion Hazard:Slight fire hazard.

Other Precautions:

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

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. At any detectable
    concentration - Any self-contained breathing apparatus that has a
    full facepiece and is operated in a pressure-demand or other
    positive-pressure mode. 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. 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 or process enclosure 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. Provide an
    emergency eye wash fountain and quick drench shower in the
    immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.
