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:
    If frostbite or freezing occur, immediately flush with plenty of
    lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm
    water is not available, gently wrap affected parts in blankets. Get
    immediate medical attention. EYE CONTACT: Flush eyes with plenty of
    water. INGESTION: If a large amount is swallowed, get medical
    attention. NOTE TO PHYSICIAN: For inhalation, consider oxygen.

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

Autoignition Temp:>1382 F (>750 C)
Extinguishing Media:carbon dioxide, regular dry chemical 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. Cool containers with water spray until well
    after the fire is out. Stay away from the ends of tanks. 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, evacuation radius: 800 meters (1/2 mile). Use extinguishing
    agents appropriate for surrounding fire. Cool containers with water
    spray until well after the fire is out. Apply water from a
    protected location or from a safe distance. Do not get water
    directly on material. Reduce vapors with water spray. 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. Containers may
    rupture or explode if exposed to heat.

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

Spill Release Procedures:Dike the spilled liquid, and either pump back
    into original container or cover with clay-type substance for
    absorption.
Neutralizing Agent:

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

Handling and Storage Precautions:Store at ambient temperature. Prevent
    possible eye and skin contact by wearing protective clothing and
    equipment.
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 supplied-air respirator with a
    full facepiece that is operated in a pressure-demand or other
    positive-pressure mode. Any self-contained breathing apparatus that
    has a full facepiece and is operated in a pressure-demand or other
    positive-pressure 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 with a full
    facepiece.
Ventilation:Provide local exhaust ventilation system. Ventilation
    equipment should be explosion-resistant if explosive concentrations
    of material are present. Ensure compliance with applicable exposure
    limits.
Protective Gloves:Wear insulated gloves.
Eye Protection:For the gas: Eye protection not required, but
    recommended. For the liquid: Wear splash resistant safety goggles.
    Contact lenses should not be worn. Provide an emergency eye wash
    fountain and quick drench shower in the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
    clothing.
