    EXPOSURE: rash, itching, digestive disorders
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: If a large amount is
    swallowed, get medical attention. NOTE TO PHYSICIAN: For
    inhalation, consider oxygen.

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

Autoignition Temp:795 F (424 C)
Lower Limits:7.0%
Upper Limits:73%
Extinguishing Media:carbon dioxide, regular dry chemical, alcohol
    resistant foam Large fires: 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. Withdraw immediately in case of rising sound from
    venting safety device or any discoloration of tanks due to fire.
    For tank, rail car or tank truck: Stop leak if possible without
    personal risk. Let burn unless leak can be stopped immediately. For
    smaller tanks or cylinders, extinguish and isolate from other
    flammables. Evacuation radius: 800 meters (1/2 mile). Do not
    attempt to extinguish fire unless flow of material can be stopped
    first. Flood with fine water spray. Cool containers with water
    spray until well after the fire i 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.
    Evacuate if fire gets out of control or containers are directly
    exposed to fire. Evacuation radius: 500 meters (1/3 mile). Consider
    downwind evacuation if material is leaking. Stop flow of gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
    are explosive. The vapor is heavier than air. Vapors or gases may
    ignite at distant ignition sources and flash back.

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Subject to storage
    regulations: U.S. OSHA 29 CFR 1910.106. Grounding and bonding
    required. Protect from physical damage. Keep separated from
    incompatible substances. Use diking sufficient to contain total
    contents plus 10%. Keep separated from incompatible substances.
    Notify State Emergency Response Commission for storage or use at
    amounts greater than or equal to the TPQ (U.S. EPA SARA Section
    302). SARA Section 303 requires facilities storing a material with
    a TPQ to participate in local emergency response planning (U.S. EPA
    40 CFR 355.30).
Other Precautions:

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

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. 7.5 ppm Any
    chemical cartridge respirator with a full facepiece and
    cartridge(s) providing protection against this substance. 75 ppm
    Any chemical cartridge respirator with a full facepiece and
    cartridge(s) providing protection against this substance. Any
    supplied-air respirator with a full facepiece that is operated in a
    pressure-demand or other positive-pressure mode. Any supplied-air
    respirator operated in a continuous-flow mode. 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
    that has a full facepiece and is operated in a pressure-demand or
    other positive-pressure mode. Escape - Any chemical cartridge
    respirator with a full facepiece and cartridge(s) providing
    protection against this substance. Any self-contained breathing
    apparatus that has a full facepiece and is operated in a
    pressure-demand or other positive-pressure mode.
Ventilation:Provide local exhaust or process enclosure ventilation
    system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves. OSHA
