    EXPOSURE: no information on significant adverse effects
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.
    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: If vomiting
    occurs, keep head lower than hips to help prevent aspiration. If
    person is unconscious, turn head to side. Get medical attention, if
    needed.


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

Flash Point:30 F (-1 C) (CC)
Autoignition Temp:743 F (395 C)
Lower Limits:1.5%
Upper Limits:12.5%
Extinguishing Media:regular dry chemical, carbon dioxide, water,
    regular foam 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. 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. Water may be ineffective.
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.

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

Spill Release Procedures:Avoid heat, flames, sparks and other 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.
    Remove sources of ignition. Keep unnecessary people away, isolate
    hazard area and deny entry.

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards.
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 chemical cartridge respirator
    with organic vapor cartridge(s). Any chemical cartridge respirator
    with a full facepiece and organic vapor cartridge(s). Any
    air-purifying respirator with a full facepiece and an organic vapor
    canister. 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. 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
 THIOPHENE: No occupational exposure limits established.
