SECTION IV ?FIRE AND EXPLOSION HAZARD DATA
Flash Point: >230癋(SETAFLASH CC)
Auto Ignition Temperature: N/D
Flammable Limits: LEL ?N/D UEL ?N/D
Extinguishing Media: Carbon dioxide, foam, dry chemical and water fog.
Special Fire & Unusual Hazards: Self-contained respirator equipment and full protective clothing are required when smoke
and fumes are generated. If water is used, use very large quantities. A very vigorous reaction may take place between water and the
hot product. Water contamination will produce gas (carbon dioxide). Do not reseal contaminated containers as pressure buildup may
rupture them.
SECTION V ?HEALTH HAZARD DATA
Primary Route(s) of Entry: Dermal
Skin Contact: Prolonged or repeated exposure may cause skin irritation and redness. Skin sensitization or allergic reaction (contact
dermatitis) may occur in some individuals.
Inhalation: No known health information on inhalation of vapors. Vapors and aerosols probably affect respiratory tract. MDI can induce
respiratory irritation with asthma-like symptoms. These symptoms may be immediate or delayed up to several hours after exposure.
There are reports that long-term exposure may result in decreased lung function.
Ingestion: Probable oral toxicity, LD(50) (rat), >10g/kg. Irritation of the mouth, pharynx, esophagus and stomach can develop upon
ingestion.
Eyes: Following contact, irritation will take place.
Other Effects of Overexposure: In a recently completed study, groups of rats were exposed for 6 hours/day, 5 days/week for a
lifetime to atmospheres of respirable polymeric MDI aerosol. Tumor incidence, both benign and malignant, and the number of animals
with tumors were not different from controls. There were no lung tumors at 1 mg/m3 and no effects at .2 mg/m3. However, at the top

level only of 6 mg/m3 there was a significant incidence of a benign tumor of the lung (adenoma) and one malignant tumor (Aden
carcinoma). The increased incidence for lung tumors is associated with the prolonged respiratory irritation and the concurrent
accumulation of yellow material in the lung that was observed throughout the study.
SECTION VI ?REACTIVITY DATA
Stability: This product must be mixed with another component or water (moisture) to react. Excessive heat, fumes, and foam
generation can occur if improperly handled. Not sensitive to mechanical impact.
Incompatibility: Strong acids, strong bases. Amines, mercaptains, polyols, water and metal compounds may initiate possible
hazardous reactions.
Hazardous Decomposition Products: Carbon monoxide and dioxide, nitrogen oxides, ammonia. Trace amounts of hydrogen
cyanide.
Hazardous Polymerization: May occur if product is not handled per instruction.
SECTION VII ?SPILL OR LEAK PROCEDURES
Wear skin, eye and respiratory protection during cleanup. All operations should be performed by personnel familiar with the hazards of
the chemicals used. Soak up material with absorbent and shovel into waste container. Cover, but do not seal waste container and
remove from work area. Make decontamination solution of .5% liquid detergent and 5% ammonium hydroxide or 7% sodium carbonate
in water. Treat spill area with decontamination solution, using about 10 parts for each part of spilled material and allow to react for 10
minutes. Carbon dioxide will form, leaving insoluble polymer material. Wash residue into sewer, observing local regulation of
discharging insoluble polymer materials.
SECTION VIII ?SPECIAL PROTECTION INFORMATION
General: No ACGIH or OSHA PEL has been assigned to this material. Minimize exposure as a good hygiene practice. For MDI, the
TLV is .005 ppm/8 hour TWA and PEL is .02 ppm, ceiling. NIOSH recommends .005 ppm TWA and .02 ppm STEL. These control
limits do not apply to previously sensitized individuals or persons with existing chronic respiratory disease. Sensitized individuals
should be removed from any further exposure.
Ventilation: Ventilation is recommended to keep vapors under TLV.
Personal Protection: Use eye protection (chemical-light goggles). Selection of specific items such as gloves, boots, and apron will
depend on the operation. Butyl or neoprene rubber garments have good resistance to permeation by MDI. Clothing constructed or
polyethylene, latex rubber or PVC has limited resistance to permeation by MDI. Wash contaminated clothing before reuse.
Respiratory Protection: When material is sprayed or heated and airborne concentrations exceed or are expected to exceed the
TLV, use MSHA/NIOSH approved positive pressure supplied air respirator with full face piece or an air supplied hood. For
emergencies, use a positive pressure self-contained breathing apparatus. Cartridge type air-purifying respirators are not approved
against isocyanates.
SECTION IX ?SPECIAL PRECAUTIONS
Precautions to be taken in handling and storage: Causes irritation. May cause allergic skin reaction. Avoid contact with eyes, skin or
clothing. Store in cool, dry area in closed cartridges.
Other precautions: Avoid breathing vapors, use with good ventilation. Wash hands thoroughly with soap and water after every use.

Salvage. Clean up residue with absorbent material. Wash down area with water and diluted acetic acid.
SECTION VIII ?SPECIAL PROTECTION INFORMATION
Ventilation: Ventilation is recommended. Air movement must be designed to insure turnover at all locations in work area to avoid the
build-up of heavy vapors.
Personal Protection: Use chemical goggles and face shield if splashing is anticipated. Wear globes. Selection of other specific items
will depend on the operation. Wear respirator protection whenever airborne concentration exceeds TLV ceiling or TWA. Use NIOSH
approved respirators for listed hazard. Confined spaces, rooms or tanks are areas where concern for TLVs is especially important.
Reference OSHA Regulation CFR 29 1910.134 for recommended respiratory protection.
