Fraction by Wt: 100.0%

=====================  Hazards Identification  =====================

Reports of Carcinogenicity:NTP:Yes    IARC:Yes	  OSHA:No
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:
    Remove contaminated clothing, jewelry, and shoes immediately. Wash
    affected area with soap or mild detergent and large amounts of
    water until no evidence of chemical remains (approximately 15-20
    minutes). EYE CONTACT: Immediately 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. ANTIDOTE: dimercaprol,
    intramuscular.

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

Extinguishing Media:water Do not use dry chemicals, carbon dioxide or
    halogenated extinguishing agents. Large fires: Flood with water.
    Apply water from a protected location or from a safe distance.
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. Flood with water. 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. Evacuate if fire gets out of control or
    containers are directly exposed to fire. Evacuation radius: 800
    meters (1/2 mile).
Unusual Fire/Explosion Hazard:Negligible fire hazard. Oxidizer. May
    ignite or explode on contact with combustible materials.

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

Neutralizing Agent:

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. NFPA 430 Code for the
    Storage of Liquid and Solid Oxidizing Materials. Protect from
    physical damage. Store in a cool, dry place. Keep separated from
    incompatible substances. Avoid storage on wooden floors. Collect
    spilled material in appropriate container for disposal. Do not
    return to original containers. 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. Measurement
    Element: Chromium (Cr) 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 a 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 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.
