SECTION 2: HAZARDS IDENTIFICATION
This material is classified as hazardous under OSHA Hazard Communication Standard (29 CFR 1910.1200)
Physical State and Appearance: Brown Liquid
Emergency Overview:
INHALATION OF MDI MISTS OR VAPORS MAY CAUSE RESPIRATORY IRRITATION, BREATHLESSNESS, CHEST
DISCOUMFORT AND REDUCED PULMONARY FUNCTION. OVEREXPOSURE WELL ABOVE THE PEL MAY
RESULT IN BRONCHITIS, BRONCHIAL SPASMS AND PULMONARY EDEMA. LONG-TERM EXPOSURE TO
ISOCYANATES HAS BEEN REPORTED TO CAUSE LUNG DAMAGE, INCLUDING REDUCED LUNG FUNCTION
WHICH MAY BE PERMANENT. ACUTE OR CHRONIC OVEREXPOSURE TO ISOCYANATES MAY CAUSE
SENSATION IN SOME INDIVIDUALS, RESULTING IN ALLERGIC RESPRATORY REACTIONS INCLUDING
WHEEZING, SHORTNESS OF BREATH AND DIFFICULTY BREATHING.
Skin: HAZARDOUS IN CASE OF SKIN CONTACT (IRRITANT, SENSITIZER). SKIN INFLAMMATION IS
IS CHARACTERIZED BY ITCHING, SCALING OR REDDENING.
Eyes: HAZARDOUS IN CASE OF EYE CONTACT (IRRITANT).
Inhalation: HAZARDOUS IN CASE OF INHALATION (LUNG IRRITANT, LUNG SENSITIZER).
Ingestion: SLIGHTLY HAZARDOUS IN CASE OF INGESTION.
Medical Conditions Aggravated by Overexposure: Preexisting conditions such as asthma, allergies, eczema,
bronchitis, and other lung and skin disorders may be aggravated by exposure to the product. Results from a lifetime
inhalation study in rats indicate that MDI aerosol was carcinogenic at 9 mg/m3, the highest dose tested. This is well above
the recommended TLV of 5ppb (0.05 mg/m3). Only irritation was noted at the lower concentration of 0.2 and 1 mg/m3. No
birth defects or teratogenic effects were reported in a teratology study with rats exposed to 1, 4, and 12 mg/m3 polymeric
MDI for 6 hr/day on days 6-15 of gestation. Embryotoxicity and fetotoxicity was reported at the top dose in the presence of
maternal toxicity. 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 a later exposure to isocyanate at levels well
below the PEL/TVL. Those symptoms, which include chest tightness, wheezing, cough, shortness of breath, or asthmatic
attack, could be immediate of 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 a decrease in lung
function, which may be permanent. Sensitization may e either temporary of permanent. Prolonged contact 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 amount s of liquid material, or even as a result of vapor-only exposure.

Aggravated Medical Conditions:
Individuals who are sensitized to isocyanates and those with preexisting lung diseases of conditions, including non-
specific bronchial hyper reactivity or asthma, must avoid all exposure to isocyanates.

*Occupational Exposure Limit(s) if available, are listed in section 8.
SECTION 4: FIRST AID MEASURES
Eyes: In case of eye contact, immediately flush eyes with large amounts of water for at least 15 minutes, keeping the
eyelids open. Get immediate medical attention.
Skin Contact: Remove contaminated clothing. In case of contact, immediately wash skin with soap and plenty of water.
If symptoms develop obtain medical attention. Contaminated clothing should be thoroughly cleaned. An MDI study has
demonstrated that a polyglycol-based skin cleaner or corn oil may be more effective than soap and water.
Inhalation: If excessive inhalation of vapor occurs, remove patient to fresh air. If not breathing, give artificial respiration,
preferably mouth-to-mouth. If breathing is difficult, qualified personnel may administer oxygen. Get immediate medical
attention.
Ingestion: If swallowed, dilute with water. DO NOT INDUCE VOMITING. Never give fluids or induce vomiting if the victim
is unconscious or having convulsions. Get immediate medical attention.
NOTES TO PHYSICIANS: There is no specific antidote to counteract the effects of MDI. Symptomatic and supportive
therapy as needed. Following severe exposure medical follow-up should be monitored for at least 48 hours.
Other First Aid Procedures: Medical supervision of all employees who handle or come into contact with MDI is
recommended. Pre-employment and periodic medical examinations with respiratory function test (PEV, PVC, as a
minimum are suggested). Persons with asthmatic conditions chronic bronchitis, other chronic respiratory diseased,
recurrent eczema or pulmonary sensitization should be excluded from working with MDI. Once a person is diagnosed as
having pulmonary sensitization (allergic asthma) to MDI, further exposure is not permissible.

Protective Clothing (Fire): Splash goggles. Full suit. Boots. Gloves. A self-contained breathing apparatus should be
used to avoid inhalation of the product.
Special Remarks on Fire Hazards: Reacts slowly with water to produce carbon dioxide, which may rupture closed
containers. This reaction accelerates at higher temperatures.
SECTION 6: ACCIDENTAL RELEASE MEASURES
For major spills call Chemtrec (800-424-9300)
Small Spill and Leak: Clean-up should only be performed by trained personnel. People dealing with major spillages
should wear full protective clothing including appropriate respiratory protection. Evacuate the area. Prevent further
leakage, spillage or entry into drains.
Large Spill and Leak: 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
with
Liquid decontaminant. Test atmosphere for MDI. Neutralize small spillages with decontaminant. Remove and properly
dispose of residues (see Section 13 for disposal considerations). Notify applicable government authorities if release is
reportable. The CERCLA RQ for 4,4-MDI is 5000 lbs (see CERCLA in Section 15).
Decontaminant: Preparation of Decontaminant 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 ammonium
hydroxide). Follow the precautions on the supplier s 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: HANDLING AND STORAGE
Handling: Avoid personal contact with the product or reaction mixture. Use only with adequate ventilation to ensure that
the occupational exposure limit is not exceeded. The efficiency of the ventilation system must be monitored regularly
because of the possibility of blockage. Avoid breathing aerosols, mists and vapors. (See Section 8 Exposure Control for
details.)
Storage: 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 reseal contaminated containers. Uncontaminated containers, free of moisture, may be
resealed only after placing under a nitrogen blanket. Do not store in containers made of cooper, cooper alloys or
galvanized surfaces.
Ideal storage temperature is 16-38 C (60-100 F).
Keep stocks of decontaminant (see Section 6) readily available.
SECTION 8: 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 bellow the TLV. Suitable
respiratory equipment should be used in cases of insufficient ventilation or where operational procedures demand it. For
guidance on engineering control measures refer to publications such as the ACGIH current edition of Industrial
Ventilation, a manual of Recommended Practice .
Personal Protection
Eyes: Chemical safety goggles. If there is a potential for splashing, use a full face shield.
4
Body and Hands: The following protective materials are recommended: Gloves-neoprene, nitrile rubber, butyl
rubber. Thin latex 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: When the product is sprayed or heated without adequate ventilation, an approved MSHA/NIOSH
positive-pressure, supplied-air respirator may be required. Air purifying respirators equipped with organic vapor cartridges
and a HEPA (P100) particulate filter may be used under certain conditions when a cartridge change-out schedule has
been developed in accordance with the OSHA respiratory protection standard (29 C.F.R. 1910.134).
Personal Protection in Case of a Large Spills: Splash goggles. Full suit. Vapor respirator or a self-contained breathing
apparatus. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling
this product.

SECTION 11: TOXICOLOGICAL INFORMATION
Toxicity to Animals: LD50 Rat Oral: >5000mg/kg
LD50 Rabbit Dermal: >5000 mg/kg
5
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. There is limited
evidence from animal studies that skin contact may play a role in respiratory sensitization. These results emphasize the
need for protective clothing including gloves to be worn at all times when handling these chemicals or in maintenance
work.
Eye Contact: The vapor, aerosol, and liquid are irritant.
Ingestion: Ingestion may cause irritation of the gastrointestinal tract. Based on the acute oral LD50 this product is
considered practically non-toxic by ingestion.
Remarks: Short term test have shown that it is unlikely to be genotoxic. (BUTYLATEDHYDROXYTOLUENE)
Carcinogenic Effects: 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.
Mutagenic Effects: There is no substantial evidence of mutagenic potential.
Reproductive Effects: No adverse reproductive effects are anticipated.
Teratogenic Effects: No birth defects were seen in two independent animal (rat) studies. Fetotoxicity was observed at
doses that were extremely toxic (including lethal) to the mother. Fetotoxicity was not observed at doses that were not
maternally toxic. The doses used in these studies were maximal respirable concentrations well in excess of the defined
limits.
Remark: A study was conducted where groups of rats were exposed for 6 hours/day, 5 days/week for a lifetime to
atmosphere of respirable polymeric MDI aerosol at concentrations of 0, 0.2, 1 or 6 mg/m3. No adverse effects were
observed at 0.2 mg/m3. At the 1mg/m3 concentration, minimal nasal and lung irritant effect were seen. Only at the top
concentration (6.0 mg/m3) was there an increased incidence of a benign tumor of the lung (adenoma). One malignant
pulmonary tumor (adenocarcinoma) was seen in the 6.0 mg/m3 group. MDI administration to rats in this study did not
change the distribution and incidence of tumors from those seen in control animals. The increased incidence of lung
tumors is associated with prolonged respiratory irritation and the concurrent accumulation of yellow material in the lung. In
the absence of prolonged exposure to high concentration leading to chronic irritation and lung damage, it is highly unlikely
that tumor formation will occur.
There are reports that excessive chronic exposure to diisocyanates may result in permanent decrease in lung function.
SECTION 12: ECOLOGICAL INFORMATION
Ecotoxicity: Polymeric MDI. LC50 (Zebra Fish) >1000 ml/l. EC50 (Daphnia magna) (24 hours) >1000 mg/l EC50 (E. Coli)
> 100ml/l.
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.
SECTION 13: DISPOSAL CONSIDERATIONS
Waste Information: The generation of waste should be avoided or minimized wherever possible.
Disposal should be in accordance with local, state, provincial or national regulations, This material is not hazardous waste
