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

LD50 LC50 Mixture:ORAL RAT LD50: 1780 MG/KG
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION: VAPORS CORROSIVE TO MUCOUS
    MEMBRANES OF UPPER RESPIRATORY TRACT. EXPOSURE TO VAPORS CAUSE
    IRRITATION OF NOSE, THROAT, COUGHING. INGESTION: CORROSIVE. CAUSES
    BURNING PAIN IN STOMACH, FOLLOW ED BY NAUSEA AND VOMITING. SKIN:
    CORROSIVE: DOES NOT CAUSE SEVERE BURNING ON CONTACT BUT CAN CAUSE
    DELAYED REACTION BURNS. IF NOT REMOVED BY WASHING, SKIN MAY REDDEN
    AND LATER TURN WHITE, WRINKLED. CO NTINUED SKIN CONTACT MAY CAUSE
    DERMATITIS. EYE: CORROSIVE: CONTACT WITH LIQUID OR VAPOR PRODUCE
    BURNING SENSATION AND TEARING.
Explanation of Carcinogenicity:NOT A KNOWN OR AN ANTICIPATED
    CARCINOGEN.
Effects of Overexposure:INHALATION: EXPOSURE TO HIGH CONCENTRATIONS
    RESULT IN SEVERE DAMAGE TO LUNGS. SYMPTOMS OF LUNG EDEMA OFTEN
    DELAYED AND AGGRAVATED BY PHYSICAL EFFORTNESS. EYE:  PAIN AND
    BLURRED VISION, PERMANENT EYE D AMAGE. APPEARANCE OF EYE BURNS MAY
    BE DELAYED. IRRITATION EFFECTS BEGIN WITH AIRBORNE CONCENTRATIONS
    AS LOW AS 0.36 MG/M3. REPEATED AND PROLONGED EXPOSURE TO VAPOR MAY
    CAUSE IRRITATION OF THE SKIN AND  CHRONIC EYE IRRITATION.
Medical Cond Aggravated by Exposure:PERSONS WITH PRE-EXISITING SKIN
    DISORDERS OR EYE PROBLEMS, OR IMPAIRED RESPIRATORY FUNCTION MAY BE
    MORE SUSCEPTIBLE TO THE EFFECTS OF THE SUBSTANCES.

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

First Aid:INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
    ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN. GET
    MEDICAL ATTENTION IMMEDIATELY. INGESTION: IF SWALLOWED, DO NOT
    INDUCE VOMITI NG. GIVE LARGE QUANTITIES OF WATER. NEVER GIVE
    ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. GET MEDICAL ATTENTION
    IMMEDIATELY. SKIN: IMMEDIATELY FLUSH SKIN WITH PLENTY OF WATER FOR
    15 MINUTES.. REMOVE  AND WASH CONTAMINATED CLOTHING AND SHOES
    BEFORE REUSE. GET MEDICAL ATTENTION IMMEDIATELY. EYE: IMMEDIATELY
    FLUSH EYES WITH PLENTY OF WATER FOR 15 MINUTES. LIFTING LOWER/UPPER
    EYELIDS OCCASIONALLY. GET  MEDICAL ATTENTION IMMEDIATELY.

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

Flash Point Method:CC
Flash Point:=48.9C, 120.F
Autoignition Temp:=316.1C, 601.F
Lower Limits:2.7
Upper Limits:10.3
Extinguishing Media:WATER SPRAY, DRY CHEMICAL, ALCOHOL FOAM, OR CARBON
    DIOXIDE. USE WATER WITH CAUTION AS MATERIAL REACTS WITH WATER.
Fire Fighting Procedures:IN EVENT OF FIRE, WEAR FULL PROTECTIVE
    CLOTHING AND NIOSH-APPROVED SELF-CONTAINED BREATHING APPARATUS WITH
    FULL FACEPIECE OPERATED IN THE PRESSURE DEMAND OR OTHER POSITIVE
    PRESSURE MODE. USE WATER SPR AY TO BLANKET FIRE, COOL FIRE EXPOSED
    CONTAINERS TO FLUSH NON-IGNITED SPILLS OR VAPORS AWAY FROM FIRE.
Unusual Fire/Explosion Hazard:ABOVE FLASHPOINT, VAPOR-AIR MIXTURES ARE
    EXPLOSIVE WITHIN FLAMMABLE LIMITS. SEALED CONTAINERS MAY RUPTURE
    WHEN HEATED. VAPORS FLOW ALONG SURFACES TO IGNITION SOURCE AND
    FLASH BACK. VIOLENT EXOTHERMIC  REACTION OCCURS WITH WATER.
    SUFFICIENT HEAT MAY PRODUCED TO IGNITE COMBUSTIBLE MATERIALS.
    SENSITIVE TO STATIC DISCHARGE.

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

Spill Release Procedures:VENTILATE AREA OF LEAK OR SPILL. WEAR PERSONAL
    PROTECTIVE EQUIPMENT. ISOLATE HAZARD AREA. KEEP
    UNNECESSARY/UNPROTECTED PERSONNEL FROM ENTERING. WATER SPRAY TO
    DISPERSE VAPORS AND DILUTE SPILLS TO NONF LAMMABLE MIXTURES, BUT BE
    AWARE OF POTENTIAL FOR VIOLENT REACTION WITH WATER. NEUTRALIZE WITH
    SODA ASH OR LIME. CONTAIN AND RECOVER LIQUID. COLLECT LIQUID IN
    CONTAINER OR ABSORB WITH INERT MATERIAL,
Neutralizing Agent:INERT MATERIALS: VERMICULITE, DRY SAND, EARTH.
    NEUTRALIZING AGENT: SODA ASH.

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

Handling and Storage Precautions:PROTECT AGAINST PHYSICAL DAMAGE. STORE
    IN COOL, DRY WELL-VENTILATED LOCATION, AWAY FROM ANY AREA WHERE
    FIRE HAZARD MAY BE ACUTE. OUTSIDE OR DETACHED STORAGE IS PERFERRED.
    SEPARATE FROM INCOMPATIBLES.  CONTAINERS SHOULD BE BONDED AND
    GROUNDED FOR TRANSFERS TO AVOID STATIC SPARKS. KEEP AWAY FROM
    WATER.
Other Precautions:USE NON-SPARKING TYPE TOOLS AND EQUIPMENT, INCLUDING
    EXPLOSION PROOF VENTILATION.  MATERIAL IS CORROSIVE TO STEEL,
    GALVANIZED IRON, COPPER, COPPER ALLOYS. CONTAINERS OF THIS MATERIAL
    MAY BE HAZARDOUS  WHEN EMPTY SINCE THEY RETAIN PRODUCT RESIDUES
    (VAPORS, LIQUID); OBSERVE ALL WARNINGS AND PRECAUTIONS  LISTED.

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

Respiratory Protection:IF EXPOSURE LIMIT IS EXCEEDED, FULL FACEPIECE
    RESPIRATOR WITH ORGANIC VAPOR CARTRIDGE MAY BE WORN UP TO 50 TIMES
    EXPOSURE LIMIT OR MAXIMUM USE CONCENTRATION  BY REGULATORY AGENCY
    OR RESPIRATOR SUPPLIE R, WHICHEVER LOWEST. FOR EMERGENCIES OR
    INSTANCES WHERE THE EXPOSURE LEVELS ARE NOT KNOWN, USE A
    FULL-FACEPIECE POSITIVE-PRESSURE, AIR-SUPPLIED RESPIRATOR.
Ventilation:A SYSTEM OF LOCAL AND/OR GENERAL EXHAUST IS RECOMMENDED TO
    KEEP EMPLOYEE EXPOSURES BELOW THE AIRBORNE EXPOSURE LIMITS.
Protective Gloves:RUBBER AND NEOPRENE ARE RECOMMENDED MATERIALS FOR
    PERSONAL PROTECTIVE EQUIPMENT
Eye Protection:USE CHEMICAL SAFETY GOGGLES AND/OR A FULL FACE SHIELD
    WHERE SPLASHING POSSIBLE.
Other Protective Equipment:WEAR IMPERVIOUS PROTECTIVE CLOTHING,
    INCLUDING BOOTS, GLOVES, LAB COAT, APRON OR COVERALLS, AS
    APPROPRIATE, TO PREVENT SKIN CONTACT. MAINTAIN EYE WASH FOUNTAIN
    AND QUICK-DRENCH FACILITIES IN WORK AREA.
