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

Reports of Carcinogenicity:NTP:No    IARC:No	OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
    nausea, vomiting, stomach pain, chest pain, difficulty breathing,
    headache, symptoms of drunkenness, hyperactivity or drowsiness,
    tingling sensation, visual disturbances, bluish skin color,
    paralysis, convulsions, coma LONG TERM EXPOSURE: fainting, blurred
    vision, nerve damage, brain damage SKIN CONTACT: SHORT TERM

    burns, blisters EYE CONTACT: SHORT TERM EXPOSURE: irritation, eye
    damage LONG TERM EXPOSURE: same as effects reported in short term
    exposure INGESTION: SHORT TERM EXPOSURE: same as effects reported
    in short term inhalation LONG TERM 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 swallowed,
    drink plenty of water, do NOT induce vomiting. Get immediate
    medical attention. Induce vomiting only at the instructions of a
    physician. Do not give anything by mouth to unconscious or
    convulsive person. NOTE TO PHYSICIAN: For ingestion, consider
    gastric lavage.

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

Autoignition Temp:999 F (537 C)
Lower Limits:10%
Upper Limits:16%
Extinguishing Media:regular dry chemical, regular foam, water 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. Fight large fires from a protected location or
    safe distance. Stay away from the ends of tanks. Dike for later
    disposal. Do not scatter spilled material with high-pressure water
    streams. Do not attempt to extinguish fire unless flow of material
    can be stopped first. Use extinguishing agents appropriate for
    surrounding fire. Flood with fine water spray. 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 or combustion by-products. Stay upwind and keep out of low
    areas. Consider downwind evacuation if material is leaking.
Unusual Fire/Explosion Hazard:Slight fire hazard. Containers may
    rupture or explode if exposed to heat.

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

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

Handling and Storage Precautions:Store and handle in accordance with
    all current regulations and standards. Notify State Emergency
    Response Commission for storage or use at amounts greater than or
    equal to the TPQ (U.S. EPA SARA Section 302). SARA Section 303
    requires facilities storing a material with a TPQ to participate in
    local emergency response planning (U.S. EPA 40 CFR 355.30). Protect
    from physical damage. Store in a cool, dry place. Store outside or
    in a detached building. Store in a well-ventilated area. Keep in
    the dark. Avoid exposure to low temperatures or freezing. Keep
    separated from incompatible substances.
Other Precautions:

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:The following respirators and maximum use
    concentrations are drawn from NIOSH and/or OSHA. At any detectable
    concentration - Any self-contained breathing apparatus that has a
    full facepiece and is operated in a pressure-demand or other
    positive-pressure mode. 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. Escape - Any air-purifying respirator with a full facepiece
    and an organic vapor canister. Any appropriate escape-type,
    self-contained breathing apparatus. 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 with a faceshield.
    Provide an emergency eye wash fountain and quick drench shower in
    the immediate work area.
Other Protective Equipment:Protective clothing is not required.
