THROAT, COUGHING, CHEST DISCOMFORT SHORTNESS OF BREATH & REDUCED
LUNG FUNCTION. EXPOS WELL ABOVE T LV MAY LEAD TO BRONCHITIS,
BRONCHIAL SPASM & PULM EDEMA. THESE EFTS ARE USUALLY REVERSIBLE.
CHRONIC: (EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ: AS A RESULT OF PREVIOUS RPTD OVEREXP
OR A SINGLE LARGE DOSE, CERTAIN INDIVIDUALS DEVELOP ISOCYANATE
SENSIT WHICH WILL CAUSE THEM TO REACT TO A LATER EXPOS TO
ISOCYANATE AT LEVELS WELL BELOW THE TLV. THESE SYMP COULD BE
IMMED/DELAYED. OVEREXP TO ISOCYANATES HAS ALSO BEEN REPORTED TO
CAUSE LUNG DMG (SUPP DATA)
Medical Cond Aggravated by Exposure:PERSONS W/PRE-EXISTING, NONSPECIFIC
BRONCHIAL HYPERREACTIVITY CAN RESPOND TO CONC BELOW TLV W/SIMILAR
SYMP AS WELL AS ASTHMA ATTACK. ASTHMA, OTHER RESP DISORDERS, SKIN
ALLERGIES, ECZEMA.

First Aid:EYE:FLUSH W/COPIOUS AMTS OF H2O FOR AT LST 15 MIN, HOLDING
LIDS OPEN ALL TIME. REFER INDIVIDUAL TO MD/OPHTHALMOLOGIST FOR
IMMED FOLLOW-UP. SKIN:REMOVE CONTAM CLTHG. WASH AFFECTED SKIN THORO
W/ SOAP & H2O. WASH CONTAM CLTHG THORO BEFORE REUSE. FOR SEVERE
EXPOS, GET UNDER SFTY SHOWER AFTER REMOVING CLTHG, THEN GET MED

Flash Point Method:PMCC
Flash Point:410F,210C
Extinguishing Media:DRY CHEMICAL, CO2, HIGH EXPANSION CHEMICAL FOAM,
WATER SPRAY FOR LARGE FIRES.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPRVD SCBA & FULL PROT
EQUIP.DURING FIRE, MDI VAPS & OTHER IRRIT, HIGHLY TOX GASES MAY BE
GENERATED BY THERMAL DECOMP/COMBUST.
Unusual Fire/Explosion Hazard:AT TEMPS GREATER THAN 400F, POLYMERIC MDI
CAN POLYMERIZE AND DECOMPOSE WHICH CAN CAUSE PRESSURE BUILD-UP IN
CLSD CNTNRS. EXPLO RUPTURE IS POSSIBLE. (SUPP DATA)

Spill Release Procedures:EVAC & VENT SPILL AREA; DIKE SPILL TO PVNT
ENTRY INTO H2O SYSTEM; WEAR FULL PROT EQUIP, INCLUDING RESP EQUIP
DURING CLEAN-UP. MAJOR SPILL: IF TEMPORARY CONTROL OF ISOCYANATE
VAPOR IS REQUIRED, A BLANK ET OF PROTEIN FOAM MAY BE PLACED OVER
(ING 17)
Neutralizing Agent:SEE SPILL PROCEDURES.

Handling and Storage Precautions:IF CONTAINER IS EXPOSED TO HIGH HEAT,
400F IT CAN BE PRESSURIZED & POSSIBLY RUPTURE. MDI REACTS SLOWLY
W/H2O TO FORM CO2 GAS.
Other Precautions:THIS GAS CAN CAUSE SEALED CNTNRS TO EXPAND & POSSIBLY
RUPTURE. STORE IN TIGHTLY CLSD CNTNRS TO PVNT MOISTURE CONTAM. DO
NOT RESEAL IF CONTAM IS SUSPECTED. AVOID CNTCT W/SKIN & EYES. EXPOS
TO VAPS OF H EATED MDI CAN BE EXTREMELY DANGEROUS.

Respiratory Protection:CONCENTRATIONS GREATER THAN THE TLV CAN OCCUR
WHEN MDI IS SPRAYED, HEATED OR USED IN A POORLY VENTILATED AREA. IN
SUCH CASES, OR WHENEVER CONC OF MDI EXCEED THE TLV, RESP PROT MUST
BE WORN. A NIOSH/ M SHA APPRVD SCBA IS RECOMMENDED.
Ventilation:LOC EXHST SHOULD BE USED TO MAINTAIN LEVELS BELOW THE TLV
WHENEVER MDI IS PROCESSED, HEATED/SPRAY APPLIED. (ING 16)
Protective Gloves:BUTYL/NITRILE RUBBER, POLYVINYL ALCOHOL.
Eye Protection:CHEM WORK GOGG/FULL LENGTH FSHLD .
Other Protective Equipment:COVER EXPOSED SKIN WITH APPROPRIATE
CLOTHING.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
EXPLO HAZ:THEREFORE, USE COLD H2O TO COOL FIRE-EXPOS CNTNRS. EFTS OF
OVEREXP:WHICH MAY BE PERMANENT. SENSIT CAN EITHER BE
TEMPORARY/PERMANENT. SKIN(ACUTE):ISOCYANATES REACT W/SKIN PROTEIN &
MOISTURE & CAN CAUSE IRRIT WHICH MAY INCLUDE THE FOLLOWING
