Section 3 鈥? Hazards Identification
EMERGENCY OVERVIEW
Health Hazards: Irritating to eyes, respiratory system and skin. Risk of serious damage to respiratory system.
May cause sensitization by inhalation and skin contact. Repeated inhalation of aerosol at
levels above the occupational exposure limit could cause respiratory sensitization. The onset
of the respiratory symptoms may be delayed for several hours after exposure. A
hyper-reactive response to even minimal concentrations of MDI may develop in sensitized
persons.
Physical Hazards: Reacts slowly with water to produce carbon dioxide that may rupture closed containers. This
reaction accelerates at higher temperatures.
Appearance: Pale yellow liquid.
Odor: Slightly musty.
Read the entire MSDS for a more thorough evaluation of the hazards.
Section 4 鈥? First Aid Measures
General: In case accident or if you feel unwell. Seek medical advice immediately (Show the label
where possible).
Inhalation: Remove patient from exposure, keep warm and at rest. Obtain medical attention. Treatment is
Symptomatic for primary irritation or bronchospasm. If breathing is labored, qualified
MSDS 鈥? AD-204-3 Page 2 of 6
personnel should administer oxygen. Apply artificial respiration if breathing has ceased or
shows signs of failing.
Skin Contact: Remove contaminated clothing. Wash affected areas thoroughly with soap and water. If
irritation, redness, or a burning sensation develops and persists, obtain medical advice.
Contaminated clothing should be thoroughly cleaned before reuse.
Eye Contact: Immediately flush eyes with running water for a minimum of 15 minutes. Hold eyelids open
during flushing. If irritation persists repeat flushing and obtain medical attention
IMMEDIATELY.
Ingestion: Do NOT induce vomiting. Provided the patient is conscious, wash out their mouth with water
then give 1 or 2 glasses of water to drink. Refer person to medical personnel for immediate
attention.
Note to Physicians: Symptomatic and supportive therapy may be needed following severe exposure. In such
cases, medical follow-up should be maintained for at least 48 hours.
Section 5 鈥? Fire-Fighting Measures
>300 oF (148.9 oC)
Flash Point:
Fire and Explosion Hazards: Containers may burst under intense heat Due to reaction with water, a
hazardous build-up of pressure could result if contaminated containers are
re-sealed.
Extinguishing Media: Carbon dioxide, dry chemical, or appropriate foam. If water is used, very
large quantities are required. Reaction between water and hot isocyanate
may be vigorous. Contain runoff water with temporary barriers.
Fire Fighting Protective Equipment: Use self-contained breathing apparatus and full protective clothing (Bunker
gear).
Hazardous Combustion Products: CO, CO2, NOx and some HCN.
Section 6 鈥? Accidental Release Measures
For major spills call Chemtrec (800) 424-9300.
Spills, Leaks, or Releases: Clean up should only be performed by trained personnel. People dealing with major
spillages should wear full protective clothing including respiratory protection. Evacuate the area. Prevent further
leakage, spillage or entry into drains. Contain and absorb large spillages onto an inert, non-flammable adsorbent
carrier (such as earth or sand). Shovel into open-top drums or plastic bags for further decontamination, if necessary.
Wash the spillage area clean with liquid decontaminant. Test atmosphere for MDI vapor. Neutralize small spillages
with decontaminant. Remove and dispose of residues. Notify applicable government authorities if release is
reportable.
Preparation of Decontamination Solution: Prepare a decontamination solution of 0.2-0.5% liquid detergent and
3-8% concentrated ammonium hydroxide in water (5-10% sodium carbonate may be substituted for the ammonium
hydroxide). Follow the precautions on the supplier鈥檚 material safety data sheets when preparing and using solution.
Use of Decontamination Solution: Allow deactivated material to stand for at least 30 minutes before shoveling
into drums. Do not tighten the bungs. Mixing with wet earth is also effective, but slower.
Section 7 鈥? Handling and Storage
Handling: Avoid personal contact with the product or reaction mixture. Use only with adequate ventilation to
ensure that the defined occupational exposure limit is not exceeded. The efficiency of the ventilation must be
monitored regularly because of the possibility of blockage. Avoid breathing aerosols, mists and vapors. When the
product is sprayed or heated, an approved MSHA/NIOSH positive-pressure, supplied-air respirator may be required.
MSDS 鈥? AD-204-3 Page 3 of 6
Storage Requirements: Material will react with atmospheric moisture. Keep containers properly sealed and when
stored indoors, in a well ventilated area. Keep contents away from moisture. Due to reaction with water, producing
CO2 gas, a hazardous build-up of pressure could result if contaminated containers are re-sealed. Do not store in
containers made of copper, copper alloys or galvanized surfaces. If a container is contaminated, do not reseal it.
Reseal containers only after placing under a nitrogen blanket.
Storage Temperature: Ideal storage temperature is 16-38oC (60-100oF).
KEEP STOCKS OF DECONTAMINANT (SEE SECTION 6) READILY AVAILABLE.
Section 8 鈥? Exposure Controls/Personal Protection
PREVENTIVE MEASURES:
Conditions of use, adequacy of engineering or other control measures, and actual exposures will dictate the need for
specific protective devices at your workplace.
Engineering Controls: Use local exhaust ventilation to maintain airborne concentrations below the TLV. Suitable
respiratory equipment should be used in cases of insufficient ventilation or where
operational procedures demand it. Follow guidelines in the ACGIH publication "Industrial
Ventilation".
PERSONAL PROTECTIVE EQUIPMENT:
Eye Protection: Chemical safety goggles. If there is a potential for splashing, use a full-face shield.
Skin Protection: The following protective materials are recommended. Gloves - neoprene, nitrile-butadiene
rubber, butyl rubber. Thin disposable gloves should be avoided for repeated or long term
use. Protective clothing should be selected and used in accordance with "Guidelines for the
Selection of Chemical Protective Clothing" published by ACGIH.
Respiratory Protection: Use a NIOSH/MSHA-approved positive pressure air-supplied respirator equipped with a
full facepiece, or an air-supplied hood, if airborne concentrations exceed or are expected to
exceed the TLV. Air purifying (cartridge type) respirator are not approved for protection
against Diisocyanate.
EXPOSURE GUIDELINES:
Medical supervision of all employees who handle or come in contact with respiratory sensitizers is recommended.
Persons with asthmatic-type conditions, chronic bronchitis, other chronic respiratory diseases or recurrent skin
eczema or sensitization should be excluded from working with this product. Once a person is diagnosed as
sensitized, no further exposure to any sensitizer should be permitted.

Section 11 鈥? Toxicology Information
TOXICOLOGICAL DATA:
Polymeric MDI:
Oral LD50 (rat) > 5,000 mg/kg
Dermal LD50 (rabbit) > 5,000 mg/kg
Inhalation LC50 (rat) = 490 mg/m3/4H (respirable aerosol)
POTENTIAL HEALTH EFFECTS:
Inhalation: This product is a respiratory irritant and potential respiratory sensitizer. Repeated inhalation
of vapor or aerosol at levels above the occupational exposure limit could cause respiratory
sensitization. Symptoms may include irritation to the eyes, nose, throat and lungs, possibly
combined with dryness of the throat, tightness of chest and difficulty in breathing. The onset
of the respiratory symptoms may be delayed for several hours after exposure. A
hyper-reactive response to even minimal concentrations of MDI may develop in sensitized
persons.
Skin Contact: Moderate irritant. Repeated and/or prolonged contact may cause skin sensitization. Animal
studies have shown that respiratory sensitization can be induced by skin contact with known
respiratory sensitizers including Diisocyanate. These results emphasize the need for
protective clothing including gloves to be worn at all times when handling these chemicals or
maintenance work.
Eye Contact: The aerosol, vapor or liquid will irritate human eyes following contact.
Ingestion: Ingestion may cause irritation of the gastrointestinal tract. Based on the oral LD50, this
product is considered practically non-toxic by ingestion.
Chronic Effects: A study where groups of rats were exposed for 6 hours/day, 5 days/week for a lifetime to
atmospheres of respirable polymeric MDI aerosol. Overall, the tumor incidence, both benign
and malignant, and the number of animals with tumors were not different from controls.
Only at the top level (6 rng/m3), there was a significant incidence of a benign tumor of the
lung (adenoma) and one malignant tumor (adenocarcinoma). There were no lung tumors at 1
mg/m3 and no effects at 0.2 mg/m3. The increased incidence of lung tumors is associated
with prolonged respiratory irritation and the Concurrent accumulation of yellow material in
the lung, which occurred throughout the study. In the absence of prolonged exposure to high
concentrations leading to chronic irritation and lung damage, it is highly unlikely that tumor
formation will occur. There are reports that chronic exposure may result in permanent
decrease in lung function.
Carcinogenicity: The ingredients of this product are not classified as carcinogenic by ACGIH or IARC, not
regulated as carcinogens by OSHA, and not listed as carcinogens by NTP.
Mutagenicity: There is no substantial evidence of mutagenic potential.

Reproductive Effects: No adverse reproductive effects are anticipated.
Teratogenicity and
Fetotoxicity: No information is available and no adverse teratogenic embryotoxic effects are anticipated.
Section 12 鈥? Ecological Information
Environmental Fate and Distribution: It is unlikely that significant environmental exposure in the air or water
will arise, based on consideration of the production and use of the
substance.
Persistence and Degradation: Immiscible with water, but will react with water to produce inert and
non-biodegradable solids.
Toxicity: Polymeric MDI
LCO (Zebra Fish) > 1000 mg/l
LC60 (Daphnia magna) (24 hour) > 1000 mg/l
EC50 (E. Coli) > 100 mg/1
