6. ACCIDENTAL RELEASE MEASURES
Shut off the source of the leak if it is safe to do so. Remove all ignition sources. Dike and contain large spills. Absorb with a suitable material, such as
sawdust, and shovel into containers. Treat with a neutralizing solution (e.g. a mixture of 80% water & 20% non-ionic surfactant Tergitol TMN-10; or a
mixture of 90% water, 8% concentrated ammonia, and 2% detergent) such that 10 parts of neutralizer are used per one part isocyanate. Allow to stand
uncovered for 48 hours to let CO2 escape, and dispose of properly. Clean-up personnel should use adequate protective equipment.
7. HANDLING AND STORAGE
Store in a cool, dry place. Keep away from moisture, ignition sources, and high temperatures. Avoid contact with incompatible materials.
Wear protective eyewear, chemical-resistant gloves, and other protective clothing as appropriate.
8. EXPOSURE CONTROLS AND PERSONAL PROTECTION
Engineering / Ventilation Controls: General ventilation may be acceptable under most conditions,
although local ventilation is required to control exposure whenever
vapors, mists, or dusts are generated. Eye wash stations should be
readily available.
Respiratory Protection: When local ventilation is unavailable and airborne limits are
exceeded, a NIOSH-approved respirator, a supplied-air respirator,
or a self-contained breathing apparatus is required.
Skin Protection: Impervious gloves and protective clothing should be worn as
necessary.
Eye Protection: Chemical splash goggles or safety glasses with side shields should
be worn as appropriate.
9. STABILITY AND REACTIVITY
Chemical Stability: Stable under normal conditions and use.
Conditions and Materials to Avoid: Keep away from moisture, ignition sources, and high temperatures.
Reacts with water, amines, strong bases, and alcohols. Will
corrode copper alloys and aluminum.
Hazardous Decomposition Products: Carbon monoxide, nitrogen oxides, and traces of other toxic gases.

11. TOXICOLOGICAL INFORMATION
This section provides toxicological information with regard to the pure form of the component indicated. It is suggested that
this information be interpreted by persons trained in its evaluation.
Diphenylmethane Diisocyanate (monomeric and polymeric)
Acute Oral LD50: >15,800 mg/kg, rat
Acute Dermal LD50: >7900 mg/kg, rabbit
Approx. 370-490 mg/m3 (four-hour), rat, for an aerosol of
Acute Inhalation LC50:
polymeric MDI; >400 mg/m3(two-hour), rat, for a dust of
monomeric MDI
A maximum primary eye irritation score of 12.0/110 (twenty-four-hour) was obtained for a polymeric MDI. This score is fairly typical for a number of MDI
products. Primary dermal irritation scores are typically below 3.4/8.0 (Draize).

MDI has been shown to produce dermal sensitization in several species: guinea pigs, rabbits, mice, and dogs. Intradermal or topical application followed by
inhalation challenge have resulted in a respiratory sensitization response in guinea pigs. In addition, there is some evidence to suggest that cross-
sensitization between different types of diisocyanates may occur.
This product does not contain, in a concentration greater than or equal to 0.1%, any carcinogenic material according to the National Toxicology Program,
IARC Monographs, or OSHA.
12. DISPOSAL CONSIDERATIONS
Keep out of surface waters, sewers, and waterways entering or leading to surface waters. Notify authorities if any exposure to the environment occurs or is
likely to occur. Utilize an appropriate disposal facility, in compliance with applicable federal, state, and local environmental control regulations.
13. TRANSPORTATION INFORMATION

11. TOXICOLOGICAL INFORMATION
This product contains trace amounts of an odorous material identified as 4-vinylcyclohexene (VCH). Under aggressive conditions of physical handling or
with heating, there is a potential for release of VCH at concentrations near the ACGIH TLV-TWA of 0.1 ppm In Russian workers exposed to high VCH
concentrations (271-677 ppm), eye and nose irritation, headache, some white blood cell reductions, and impaired carbohydrate metabolism were reported.
Repeated administration of VCH to rats and mice by inhalation (four-month) was reported to produce some white blood cell reductions and blood circulation
effects. Repeated oral dosing (three-month) of rats and mice produced kidney toxicity in male rats and ovarian effects in female mice at a dose that caused
many animal deaths
