Health Hazards Acute and Chronic:INHALATION-HIGHLY TOXIC BY INHALATION.
    DEATH MAY OCCUR FROM RENAL FAILURE. INGESTION-MAY BE HIGHLY TOXIC
    THROUGH INGESTION. SKIN-CAUSES IRRITATION. EYE-VAPORS CAUSE
    IRRITATION. CONTACT MAY CAUSE IRRIT ATION OR EYE DAMAGE. CHRONIC:
    PROLONGEDEXPOSURE MAY CAUSE CENTRAL NERVOUS SYSTEM DEPRESSION,
    LIVER & KIDNEY DAMAGE.
Explanation of Carcinogenicity:1,4-DIOXANE IF LISTED AS A CARCINOGEN BY
    NTP.
Effects of Overexposure:INHALATION-SYMPTOMS INCLUDE IRRITATION OF THE
    RESPIRATORY TRACT, HEADACHE, NAUSEA, VOMITING, DIZZINESS &
    NARCOSIS. INGESTION/SKIN-SYMPTOMS EXPECTED TO PARALLEL INHALATION.
    CHRONIC: LOSS OF APETITE, NA USEA, ABDOMINAL TENDERNESS.
Medical Cond Aggravated by Exposure:PERSONS WITH PRE-EXISTING SKIN
    DISORDERS OR EYE PROBLEMS, OR IMPAIRED LIVER, KIDNEY OR RESPIRATORY
    FUNCTIONS MAY BE MORE SUSCEPTIBLE TO THE EFFECTS OF THE SUBSTANCE.

=======================  First Aid Measures  =======================

First Aid:INHALATION:REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
    ARTIFICIAL RESPIRATION. IF BREATHING IS HARD, GIVE OXYGEN. CALL
    PHYSICIAN. INGEST:IF SWALLOWED, INDUCE VOMITING BY GIVING 2 GLASSES
    OF WATER & ST ICKING FINGER DOWN THROAT. SKIN-IMMEDIATELY FLUSH
    SKIN WITH PLENTY OF WATER FOR AT LEAST 15 MIN. CALL PHYSICIAN.
    EYE-WASH EYE WITH PLENTY OF WATER FOR AT LEAST 15 MIN. GET MEDICAL
    ATTENTION.

Extinguishing Media:DRY CHEMICAL, FOAM OR CARBON DIOXIDE. WATER SPRAY
    MAY BE USED TO KEEP FIRE EXPOSED CONTAINERS COOL.
Fire Fighting Procedures:IN THE EVENT OF A FIRE, WEAR FULL PROTECTIVE
    CLOTHING & NIOSH-APPROVED SELF-CONTAINED BREATHING APPARATUS WITH
    FULL FACEPIECE OPERATED IN THE PRESSURE DEMAND.
Unusual Fire/Explosion Hazard:ABOVE FLASH POINT, VAPOR-AIR MIXTURES ARE
    EXPLOSIVE WITHIN FLAMMABLE LIMITS. VAPORS CAN FLOW ALONG SURFACES
    TO DISTANT IGNITION SOURCES & FLASH BACK.

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

Spill Release Procedures:VENTILATE AREA OF LEAK OR SPILL. REMOVE ALL
    SOURCES OF IGNITION. CLEANUP PERSONNEL REQUIRE PROTECTIVE CLOTHING
    & RESPIRATORY PROTECTION FROM VAPORS. CONTAIN & RECOVER LIQUID WHEN
    POSSIBLE.

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

Handling and Storage Precautions:PROTECT AGAINST PHYSICAL DAMAGE. STORE
    IN COOL, DRY WELL VENTED ALOCATION, AWAY FROM DIRECT SUNLIGHT & ANY

    STORAGE PREFERRED. INSIDE STORAGE SHOULD BE IN A STANDARD FLAMMABLE
    LIQUIDS STORAGE ROOM OR CABINET. SEPERATE FROM OXIDIZING MATERIALS.
    CONTAINERS	SHOULD BE BONDED AND GROUNDED.

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

Respiratory Protection:IF THE TLV IS EXCEEDED A FULL FACEPIECE CHEMICAL
    CARTRIDGE RESPIRATOR MAY BE WORN, IN GENERAL. ALTERNATIVELY, A
