source of exposure Limit Data:
1. AcGIH Threshold Limit Values
2. Federal osHA Permissible exposure limit
3. DAI exposure Guidelines
4. chemical Manufacturer Recommended Guidelines
5. none established Abbreviations: n/a-not applicable, n/d-

Threshold Limit Value: none established, 0.005 ppm is
recommended. 0.010 ppm is the ceiling TLV by osHA and
0.005 ppm is the TWA TLV from AcGIH for
Dicyclohexylmethane-4-4’’-diisocyanate.
Routes of entry: At room temperature by skin absorption. At
high temperatures or if the material is atomized, by inhalation
and skin absorption.
signs and symptoms of exposure:
eyes:
Redness, irritation, tearing, burning sensation.
skin: Rash, redness, itching.
Inhalation: Irritation of the respiratory tract, runny nose, sore
throat, coughing and reduction of lung function.
Hypersensitivity, indicated by asthmatic reaction is possible
in some individuals. smarting and weeping of the nose and
throat indicate that the diisocyanate concentration in the air
is above acceptable limits.
Acute effects of overexposure:
Inhalation: Irritation of the respiratory tract, runny nose, sore
throat, coughing and reduction of lung function.
Hypersensitivity, indicated by asthmatic reaction is possible
in some individuals. smarting and weeping of the nose and
throat indicate that the diisocyanate concentration in the air
is above acceptable limits. once sensitized an individual may
react allergically to airborne levels below the exposure limits.
skin: Prolonged or repeated contact may cause irritation,
redness, swelling and dermatitis. some individuals may
become hypersensitized. once sensitized an individual may
react allergically to airborne levels below the exposure limits.
eyes: Liquid and vapors are irritating.
Ingestion: Irritation and burning of mouth, throat and
stomach.
chronic effects of exposure: some individuals may become
hypersensitized and react allergically with dermatitis or
asthma when exposed to airborne levels below the exposure
limits. Development Associates, Inc MsDs Z7250 Iso Page

Medical conditions Aggravated by exposure: Dermatitis,
Asthma, other respiratory ailments, skin conditions.
carcinogenicity: This product and its constituents are not
listed as carcinogens by IARc, nTP or regulated as
carcinogens by osHA at this time.
4. First Aid Measures
emergency and First Aid Procedures:
eyes: Flush with water for at least 15 minutes. consult an
ophthalmologist.
skin contact: Remove contaminated clothing. Wash
affected areas thoroughly, with soap and water. cover
affected area with polyethylene glycol (300-500 mw.) or
glycerin and wash again with soap and water. Apply
moisturizing cream. consult physician. Treat dermatitis
symptomatically. Wash clothing before reusing.
Inhalation: Move to fresh air. Administer oxygen or artificial
respiration as needed. consult physician.
Treat symptomatically.
Ingestion: Do not induce vomiting. Give milk or water.
Do noT GIVe AnYTHInG BY MoUTH To An
UnconscIoUs PeRson. consult a physician.
5. Fire and Explosion Data
Flash Point >395°F (202°c) Tcc
Flammable Limits in Air % Volume: Upper: n/a Lower: n/a
extinguishing Media: Foam, co2, or Dry chemical
Unusual Fire and explosion Hazards: During a fire,
diisocyanate vapors and other irritating, highly toxic gasses
may be generated by thermal decomposition or combustion.
extremely high temperatures may cause closed containers to
pressurize resulting in explosive rupture.
special Fire Fighting Procedures: Use full emergency
equipment with self-contained breathing apparatus.
Use cold water to cool fire-exposed containers.
6. Accidental Release Measures
steps to be Taken in case Material is Released or spilled:
Remove unnecessary personnel. Ventilate area.
equip clean-up crew with appropriate protective gear. Leaks
should be stopped and spill dyked to control spreading.
cover spill with absorbent material such as Zip-Zorb
(activated clay), diatomaceous earth, or saw dust. sprinkle
on a decontaminating solution of 25% household ammonia,
73% water, and 2% detergent. Allow to react for 15 to 30
minutes, collect in containers, add more decontamination
solution, cover loosely. Wash down area with soap and
water, rinse.
