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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    irritation, nausea, vomiting, difficulty breathing, dizziness LONG
    TERM EXPOSURE: no information on significant adverse effects SKIN
    CONTACT: SHORT TERM EXPOSURE: irritation LONG TERM EXPOSURE: same
    as effects reported in short term exposure EYE CONTACT: SHORT TERM
    EXPOSURE: irritation LONG TERM EXPOSURE: same as effects reported
    in short term exposure INGESTION: SHORT TERM EXPOSURE: nausea,
    stomach pain LONG TERM EXPOSURE: no information is available
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 a large amount
    is swallowed, get medical attention.

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

Flash Point:77 F (25 C) (CC)
Autoignition Temp:381 F (194 C)
Lower Limits:1.5%
Upper Limits:7.6%
Extinguishing Media:alcohol resistant foam, carbon dioxide, regular dry
    chemical, water, alcohol resistant foam 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). 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. May form explosive peroxides. 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. May form peroxides during prolonged storage. Store in a
    tightly closed container. Avoid contact with light. Store in a
    cool, dry place. Check peroxide content before use. Do not
    evaporate or distill to dryness. Keep separated from incompatible
    substances. Protect from physical damage. Store outside or in a
    detached building. Store with flammable liquids. 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 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 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
 DIBUTYL ETHER: No occupational exposure limits established.
