=============  Composition/Information on Ingredients  =============

Ingred Name:PROPYLENE
CAS:115-07-1
Fraction by Wt: 100.0%

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

Reports of Carcinogenicity:NTP:No    IARC:No	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:
    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: Contact with liquid:
    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  =====================

Flash Point:-162 F (-108 C)
Autoignition Temp:851 F (455 C)
Lower Limits:2.0%
Upper Limits:11.1%
Extinguishing Media:carbon dioxide, regular dry chemical 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). Stop flow of
    gas.
Unusual Fire/Explosion Hazard:Severe fire hazard. Vapor/air mixtures
    are explosive above flash point. The vapor is heavier than air.
    Vapors or gases may ignite at distant ignition sources and flash
    back. Electrostatic discharges may be generated by flow or
    agitation resulting in ignition or explosion.

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

Spill Release Procedures:Avoid heat, flames, sparks and other sources
    of ignition. Do not touch spilled material. Stop leak if possible
    without personal risk. Reduce vapors with water spray. Keep
    unnecessary people away, isolate hazard area and deny entry. Remove
    sources of ignition. Ventilate closed spaces before entering.
Neutralizing Agent:

======================	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 1910.110. Protect from physical
    damage. Store in a cool, dry place. Store in a well-ventilated
    area. Avoid heat, flames, sparks and other sources of ignition.
    Store outside or in a detached building. Grounding and bonding
    required. Subject to storage regulations: U.S. OSHA 29 CFR
    1910.101. Keep separated from incompatible substances.
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. 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:Ventilation equipment should be explosion-resistant if
    explosive concentrations of material are present. Provide local
    exhaust ventilation system. 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:For the gas: Protective clothing is not
    required. For the liquid: Wear appropriate protective, cold
    insulating clothing.
