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 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:
    Get medical attention immediately. NOTE TO PHYSICIAN: For
    inhalation, consider oxygen.   For ingestion, consider gastric
    lavage.

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

Flash Point:-18 F (-28 C) (CC)
Autoignition Temp:527 F (275 C)
Lower Limits:1.5%
Upper Limits:8.7%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
    chemical, water Large fires: Use alcohol-resistant 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. 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: 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. Do not
    scatter spilled material with high-pressure water streams. 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 ocombustion by-products. Stay upwind and
    keep out of low areas.
Unusual Fire/Explosion Hazard:Severe fire hazard. The vapor is heavier
    than air. Vapors or gases may ignite at distant ignition sources
    and flash back. Vapor/air mixtures are explosive. 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. Remove sources of ignition. Stop leak if possible
    without personal risk. Reduce vapors with water spray. Small
    spills: Absorb with sand or other non-combustible material. Collect
    spilled material in appropriate container for disposal. Large
    spills: Dike for later disposal. Keep unnecessary people away,
    isolate hazard area and deny entry. Stay upwind and keep out of low
    areas.
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 1910.106. Grounding and bonding
    required. 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. 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 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.
Supplemental Safety and Health
 1-PENTENE: No occupational exposure limits established.
