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

LD50 LC50 Mixture:NO DATA PROVIDED BY MANUFACTURER
Reports of Carcinogenicity:NTP:UNKNOWN	  IARC:YES
Health Hazards Acute and Chronic:EYE CONTACT WITH ISOCYNATES MAY RESULT
    IN CONJUNCTIVAL IRRITATION & MILD CORNEAL OPACITY. SKIN CONTACT MAY
    RESULT IN DERMATITIS, EITHER IRRITATIVE OR ALLERGIC. INHALATION OF
    MDI VAPORS MAY CAUSE IRRIT ATION OF THE MUCOUS MEMBRANES OF THE
    NOSE, THROAT OR TRACHEA AND REDUCED PULMONARY FUNCTION. AIRBORNE
    OVEREXPOSURE WELL ABOVE THE PEL MAY RESULT ADDITIONALLY IN EYE
    IRRITATION,  CHEMICAL BRONCHITIS, A STHMA-LIKE FINDINGS OR
    PULMONARY EDEMA. ISOCYANATES HAVE ALSO BEEN REPORTED TO CAUSE
    HYPERSENSITIVITY PNEUMONITIS. GASTROINTESTINAL SYMPTOMS INCLUDE
    NAUSEA, VOMITING AND ABDOMINAL PAIN. CHRONIC: SEE T OXICOLOGICAL.
Explanation of Carcinogenicity:RESULTS FROM A LIFETIME INHALATION STUDY
    IN RATS INDICATE THAT MDI AEROSOL WAS CARCINOGENIC AT 6 MG/M3, THE
    HIGHEST DOSE TESTED. DLA-HMIS: LISTED AS IARC GROUP 3
    (UNCLASSIFIABLE AS TO CARCINOGENICITY  TO HUMANS, VOL. 19, SUPPL 7,
    1987).
Effects of Overexposure:EYE CONTACT WITH ISOCYNATES MAY RESULT IN
    CONJUNCTIVAL IRRITATION & MILD CORNEAL OPACITY. SKIN: DERMATITIS.
    INHALATION: BREATHLESSNESS, CHEST DISCOMFORT, DIFFICULT BREATHING
    AND REDUCED PULMONARY FUNC TION. AIRBORNE OVEREXPOSURE WELL ABOVE
    THE PEL MAY RESULT ADDITIONALLY IN EYE IRRITATION, HEADACHE,
    CHEMICAL BRONCHITIS, ASTHMA-LIKE FINDINGS OR PULMONARY EDEMA,
    FLU-LIKE SYMPTOMS. INGESTION: NAUSEA,  VOMITING, ABDOMINAL PAIN.
Medical Cond Aggravated by Exposure:INDIVIDUALS WHO ARE SENSITIZED TO
    ISOCYANATES AND THOSE WITH PREEXISTING LUNG DISEASES OR CONDITIONS,
    INCLUDING NON-SPECIFIC BRONCHIAL HYPERREACTIVITY OR ASTHMA, MUST
    AVOID ALL EXPOSURE TO ISOCYNATES.

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

First Aid:SKIN: WASH AFFECTED AREAS WITH SOAP AND WATER. REMOVE AND
    LAUNDER CONTAMINATED CLOTHING BEFORE REUSE. GET IMMEDIATE MEDICAL
    ATTENTION. EYES: IMMEDIATELY RINSE EYES WITH RUNNING WATER FOR 15
    MINUTES. G ET IMMEDIOATE MEDICAL ATTENTION. INGESTION: IF
    SWALLOWED, DILUTE WITH WATER. DO NOT INDUCE VOMITING. NEVER GIVE
    FLUIDS OR INDUCE VOMITING IF THE VICTIM IS UNCOUNSCIOUS OR HAVING
    CONVULSIONS. GET IMMED IATE MEDICAL ATTENTION. INHALATION: MOVE TO
    FRESH AIR. AID IN BREATHING, IF NECESSARY, AND GET IMMEDIATE
    MEDICAL ATTENTION.

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

Flash Point Method:COC
Flash Point:=220.C, 428.F
Extinguishing Media:USE WATER FOG, FOAM, CO2 OR DRY CHEMICAL
    EXTINGUISHING MEDIA.
Fire Fighting Procedures:PERSONNEL ENGAGED IN FIGHTING ISOCYANATE FIRES
    MUST BE PROTECTED AGAINST NITROGEN DIOXIDE FUMES AS WELL AS
    ISOCYANATE VAPORS. FIREFIGHTERS MUST WEAR SELF-CONTAINED BREATHING
    APPARATUS AND TURNOUT GEAR .
Unusual Fire/Explosion Hazard:AVOID WATER CONTAMINATION IN CLOSED
    CONTAINERS OR CONFINED AREAS (CO2 EVOLVED).

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

Spill Release Procedures:ABSORB THE ISOCYANANATE WITH AN ACCEPTABLE
    ABSORBENT. SEE 40 CFR SECTIONS 260, 264, AND 265 FOR FURTHER
    INFORMATION. SHOVEL INTO OPEN TOP CONTAINERS. DO NOT MAKE PRESSURE
    TIGHT. TRANSPORT TO A WELL VE NTILATED AREA (OUTSIDE) AND TREAT
    WITH NEUTRALIZING SOLUTION CONSISTING OF A MIXTURE OF 90% WATER,
    3-8% AMONIA AND 2-7% DETERGENT. ADD ABOUT 10 PARTS NEUTRALIZER PER
    PART ISOCYANATE. LET SIT 48 HRS.
Neutralizing Agent:NEUTRALIZING SOLUTION CONSISTING OF A MIXTURE OF 90%
    WATER, 3-8% AMONIA AND 2-7% DETERGENT.

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

Handling and Storage Precautions:KEEP CONTAINERS CLOSED AND STORE IN A
    WELL-VENTILATED AREA AT 60-80 DEG. F. OUTAGE OF CONTAINER SHOULD BE
    FILLED WITH DRY INERT GAS AT ATMOSPHERIC PRESSURE TO AVOID REACTION
    WITH MOISTURE. CONTAMINATI ON BY MOISTURE OR BASIC COMPOUNDS CAN
    CAUSE DANGEROUS PRESSURE BUILDUP IN CLOSED CONTAINERS.
Other Precautions:IF BULGING DRUM OCURS, TRANSFER TO WELL VENTILATED
    AREA, PUNCTURE TO RELIEVE PRESSURE, OPEN VENT AND LET STAND FOR 48
    HOURS BEFORE RESEALING.

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

Respiratory Protection:IF THE PERMISSIBLE EXPOSURE LIMIT IS EXCEEDED,
    WEAR A NIOSH APPROVED AIR-SUPPLIED RESPIRATOR.
Ventilation:USE LOCAL EXHAUST AS NECESSARY TO MAINTAIN P.E.L.
Protective Gloves:RUBBER GLOVES.
Eye Protection:WEAR FITTED CHEMICAL GOGGLES OR FACE SHIELD AND SAFETY
    GLASSES.
Other Protective Equipment:COVERALLS, HARD HAT, BOOTS AND RUBBER APRON
    TO AVOID SKIN CONTACT. CONTAMINATED EQUIPMENT OR CLOTHING SHOULD BE
    CLEANED AFTER EACH USE OR DISPOSED OF.
Work Hygienic Practices:EYEWASH FOUNTAINS AND SAFETY SHOWERS MUST BE
    EASILY ACCESSIBLE. MAINTAIN WORK AREA BELOW P.E.L.
Supplemental Safety and Health
NOTE TO PHYSICIANS: THERE IS NO SPECIFIC ANTIDOTE TO COUNTERACT THE
    EFFECTS OF MDI. CARE SHOULD BE SUPPORTIVE AND TREATMENT SHOULD BE
    BASED ON THE JUDGEMENT OF THE PHYSICIAN IN RESPONSE TO THE REACTIO
