Extinguishing Media
Dry chemical (e.g. monoammonium, phosphate, potassium sulfate, and potassium chloride),
carbon dioxide, high expansion (proteinic) chemical foam, water spray for large fires. Special
Fire Fighting Procedures: Full emergency equipment with self-contained breathing apparatus and
full protective clothing should be worn by fire fighters. During a fire, MDI vapors and other
irritating, highly toxic gases may be generated by thermal decomposition or combustion (see
Section VII). At temperature greater than 400?F. (204?C), polymeric MDI can polymerize and
decompose which can cause pressure build up in closed containers. Explosive rupture is
possible. Therefore, use cold water to cool fire-exposed containers.
Section V ?Health Hazard Data
Route of entry: Skin contact from liquid and aerosols (spray application), inhalation. Although
MDI is low in volatility, and inhalation hazard can exist from MDI aerosols or vapors formed
during heating or spraying.
Human Effects and Symptoms of Overexposure
Acute Inhalation:MDI vapors or mist at concentrations above the TLV can irritate (burning
sensation) the mucous membranes in the respiratory tract (nose, throat, lungs) causing runny
nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function
(breathing obstruction). Persons with a preexisting, nonspecific bronchial hyperactivity can
respond to concentrations below the TLV with similar symptoms as well as an asthma attack.
Exposure well above the TLV may lead to brochchitis, bronchial spasm and pulmonary edema
(fluid in lungs). These effects are usually chills) has also been reported. Solvent vapors may be
irritating to the eyes, nose and throat. These symptoms can be delayed up to several hours after
exposure.
U-106 Page 3 of 9
Section V ?Health Hazard Data Cont'd
Chronic Inhalation-As a result of previous repeated overexposures or a single large dose,
certain individuals will develop isocyanate sensitization (chemical asthma) which will cause
them to react to later exposure to isocyanate at levels well below the TLV. These symptoms,
which include: chest tightness, wheezing, cough, shortness of breath or asthmatic attack, could
be immediate or delayed up to several hours after exposure. Similar to many non-specific
asthmatic responses, there are reports that once sensitized, an individual can experience these
symptoms upon exposure to dust, cold air or other irritants. This increased lung sensitivity can
persist for weeks and in severe cases for several years. Chronic overexposure to isocyanates has
also been reported to cause lung damage, including decrease in lung function, which may be
permanent. Chronic exposure to organic solvents has been associated with various neurotoxic
effects including permanent brain and nervous system damage. Symptoms include: loss of
memory, loss of intellectual ability and loss of coordination.
Acute Skin Contact-Isocyanates react with skin protein and moisture and can cause irritation.
Symptoms of skin irritation may be reddening, swelling, rash, scaling or blistering. Some
persons may develop skin sensitization from skin contact. Cured material is very difficult to
remove. Repeated or prolonged skin contact can result in dry, defatted and cracked skin causing
increased susceptibility to infection. In addition, skin irritation (i.e. redness, swelling), which
can develop into dermatitis.
Chronic Skin Contact-Prolonged contact with the isocyanate can cause reddening, swelling,
rash, scaling or blistering. In those who have developed a skin sensitization, these symptoms can
develop as a result of contact with very small amounts of liquid material or even as a result of
vapor only exposure. Animal tests have indicated respiratory sensitization can result from skin
contact with MDI.
Acute Eye Contact-Liquid, aerosols, and vapors of this product (isocyanate solvents) are
irritating and can cause tearing, reddening and swelling accompanied by a stinging can occur and
injury is slow to heal. However, damage is usually reversible.
Chronic Eye Contact-None determined.
Acute Ingestion-Can result in irritation and possible corrosive action in the mouth, stomach
tissue and digestive tract. However, it is not considered a common occupational route of
exposure.
Chronic Ingestion-None determined.
Carcinogenicity-None of the components of this product are listed by the NTP, IARC, or
regulated by OSHA as carcinogens.
Medical Conditions Aggravated by Exposure: Asthma and other respiratory disorders
(bronchitis, emphysema, hyperactivity), skin allergies, eczema.
Exposure Limits: Not established for product as a whole. Refer to Section II for exposure
limits of hazardous constituents.
Emergency and First Aid Procedures
Eye Contact-Flush with copious amounts of lukewarm water for a minimum of 15 minutes,
while lifting eyelids. Contact eye physician for immediate follow up.
U-106 Page 4 of 9
Emergency and First Aid Procedures Cont'd
Skin Contact-Remove contaminated clothing. Wash skin thoroughly with water and soap.
Wash contaminated clothing before reuse. Seek medical attention if irritation develops or
persists.
Ingestion-Do not induce vomiting. Give 1 to 2 cups of milk or water to drink. Do not give
anything by mouth to an unconscious or convulsing person. Consult a physician.
Inhalation-Remove to fresh air. Administer oxygen or artificial respiration as needed. Obtain
medical attention. Asthmatic-type symptoms may develop and may be immediate or delayed up
to several hours. Consult a physician should this occur.
NOTE TO PHYSICIAN...
Eyes-Stain for evidence of corneal injury. If corneal is burned, instill antibiotic/steroid
preparation frequently. Workplace vapors could produce reversible corneal epithelial edema
impairing vision.
Skin-This product is a known skin sensitizer. Treat symptomatically as for contact dermatitis or
thermal burn.
Ingestion-Treat symptomatically. There is no specific antidote. Inducing vomiting is
contraindicated because of the irritating nature of the product.
Inhalation-This product is a known pulmonary sensitizer. Treatment is essentially
symptomatic. An individual having a dermal or pulmonary sensitization reaction to this material
must be removed from any further exposure to any isocyanate.
Section VI-Employee Protection
Eye Protection Requirements...Liquid chemical goggles. Vapor resistant goggle should be
worn when contact lenses are in use. In a splash hazard environment chemical goggles should
be worn along with a full face shield.
Skin Protection Requirements...Permeation resistant gloves (butyl rubber, nitrile rubber,
polyvinyl alcohol). However, please note that PVA degrades in water. cover as much of the
exposed skin area as possible with appropriate clothing. If skin creams are used, keep the area
covered by the cream to a minimum.
Respiratory Requirements...Concentrations greater than TLV can occur when MDI is sprayed,
heated or used in poorly ventilated areas. In such case, or whenever concentrations of MDI
exceed the TLV, respiratory protection must be worn. A positive pressure, supplied air-
respiratory of self-contained breathing apparatus if recommended. In situations where MDI is
not sprayed, heated or used in a poorly ventilated area, and a supplied air or self-contained
breathing apparatus in unavailable or its use impractical, at least an air-purifying respirator
equipped with an organic vapor cartridge and particulate pre-filters must be worn. However, this
should be permitted only for short periods of time at relatively low concentrations (at or below
the TLV). However, due to the poor warning properties of MDI, proper fit and timely
replacement of filter elements must be ensured. Observe OSHA regulations for respiratory use
(29 CFR 1910.134).
U-106 Page 5 of 9
Section VI-Employee Protection Cont'd
Ventilation Requirements...Exhaust ventilation sufficient to keep the airborne concentrations
of MDI and solvent below the respective TLV to be utilized. Standard reference sources
regarding industrial ventilation (i.e. ACGIH industrial ventilation) should be consulted for
guidance about adequate ventilation.
Additional Protective Measures...Safety showers and eyewash stations should be available
Educate and Train employees in safe use of product. Follow all label instructions.
Section VI-Toxicological Information:
Toxicity Data For: Diphenylmethane Diisocyanate (Monomeric and Polymeric)
Acute Toxicity
Oral LD50..............: Greater than 15,800 mg/kg (Rat)
Dermal LD50.........: Greater 5010 but less than 7,940 mg/kg (Rabbit)
Inhalation LC50...: The 4-hour LC50 for polymeric MDI in rats ranges from
370 to 490 mg/m3.......: The LC50 for monomeric MDI was estimated to be between 172 and
187 mg/m3.
Eye Effects..........: Slight to moderate irritation.
Skin Effects.........: Slight to moderate irritation.
Sensitization......: MDI has been shown to produce dermal sensitization in laboratory animals.
Evidence of respiratory sensitization has also been observed in guinea pigs. In addition, there is
some evidence suggestive of cross-sensitization between different types of diisocyanates.
Chronic Toxicity..: In a combined chronic inhalation toxicity/oncogenicity study, rats were
exposed to an aerosol of polymeric MDI for 6 hours per day, 5 days per week for one or two
years. The exposure concentrations were 0, 0.2, 1.0 and 6.0 mg/m3. Microscopic examination
of tissues revealed the effects of irritation to the nasal cavity and lungs in animals exposed to 1.0
and 6.0 mg/m3. The No Observable Effect Level (NOEL) was 0.2 mg/m3.
Carcinogenicity..: In the study described above (See CHRONIC TOXICITY), the occurrence of
pulmonary adenomas and a single pulmonary adenocarcinoma was considered to be related to
MDI. These tumors were observed only in rats considered to be related to MDI. These tumors
were observed only in rats exposed to the high concentration of 6.0 mg/m3.
Mutagenicity......: MDI has been reported by NIOSH to be mutagenic to samonella
typhemurium bacteria in the presence of a mammalian activating system. Recent work done by
M. Anderson, at the Danish School or Pharmacy in Denmark and published in the Scandinavian
Journal of Work and Environmental Health, also shows a positive result for Desmodur E 21.
There is not full agreement in the scientific community on the significance of these Ames test
results and their relationship to human safety in the risk of cancer in man.
Developmental Toxicity: Rats were exposed to polymeric MDI at air concentrations of 0, 1, 4,
and 12, mg/m3 during days 6-15 of gestation. Maternal Toxicity (including mortality) was
observed at the highest concentration of 12 mg/m3 accompanied by embryo and fetal toxicity.
However, no teratogenic effects were observed even at this lethal concentration.

Section VIII - Spill or Leak Procedures
If material is spilled: evacuate nonessential personnel. Ventilate area. Control further spillage is
feasible. Notify appropriate authorities if necessary. Equip clean up crew with appropriate
protective equipment (see Section VI). Dike or impound spilled material. Cover the spill with
sawdust, vermiculite, fuller's earth or other absorbent material. Shovel into suitable unsealed
containers and transport to well-ventilated area (outside). Cover loosely.
Waste Disposal Method-Waste must be disposed of in accordance with federal, state, and local
environmental control regulations. Incineration is preferred method. Empty containers must be
handled with care due to product residue. Do not heat or cut empty container with electric of gas

U-106 Page 7 of 9
Section IX ?Special Precautions and Storage Data
Storage Temperature (min/max)...................32篎. (0篊.)/122篎. (50篊.)
Shelf Life.............................................12 months at 77篎. When stored in a sealed
container.
Special Sensitivity: If container is exposed to high heat, it can be pressurized and possibly
rupture explosively. MDI reacts with water to form CO2 gas. This can cause sealed containers
to expand and possibly rupture explosively.
Handling and Storage Precautions: Store in tightly closed containers to prevent moisture
contamination. Do not reseal if contamination is suspected. Avoid contact with skin and eyes.
Do not breathe vapor. Warning properties (irritation of the eyes, nose and throat or odor) are not
adequate to prevent chronic overexposure from inhalation. This material can produce asthmatic
sensitization upon either single inhalation exposure to a relatively high concentration or upon
repeated inhalation exposures to lower concentrations. Exposure to vapors of heated MDI can
be extremely dangerous. Employee education and training in the safe use and handling of this
product are required under the OSHA Hazard Communication Standard.
