*  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.
    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
    N OF THE PATIENT.

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
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
    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
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
    INFORMATION. SHOVEL INTO OPEN TOP CONTAINERS. DO NOT MAKE PRESSURE
    TIGHT. TRANSPORT TO A WELL VE NTILATED AREA (OUTSIDE) AND TREAT
    WATER, 3-8% AMONIA AND 2-7% DETERGENT.
*Handling and Storage  *
Handling and Storage Precautions:KEEP CONTAINERS CLOSED AND STORE IN A
    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
    HOURS BEFORE RESEALING.

*  Toxicological Information*
Toxicological Information:RESULTS FROM A LIFETIME INHALATION STUDY IN
    RATS INDICATE MDI AERSOL WAS CARCINOGENIC AT 6 MG/M3, THE HIGHEST
    DOSE TESTED. THIS IS WELL ABOVE THE RECOMMENDED TLV OF 5 PPB. ONLY
    IRRITATION WAS NOTED AT  THE LOWER CONCENTRATION OF 0.2 & 1 MG/M3.
    NO BIRTH DEFECTS OR TERATOGENIC EFFECTS WERE REPORTED IN A
    FETOTOXICITY WAS REPORTED AT THE TO P DOSE IN THE PRESENCE OF
    MATERNAL TOXICITY. AS A RESULT OF PREVIOUS REPEATED OVEREXPOSURES
    OR A SINGLE LARGE (CHEMICAL ASTHMA) WHICH WILL CAUSE THEM TO REACT
    TO A LATER EXPOSURE TO ISOCYANATE AT LEVE LS WELL BELOW THE TLV
