2. HAZARDS IDENTIFICATION
This material is classified as hazardous under OSHA Hazard Communication Standard (29 CFR 1910.1200).
Physical State and Appearance Liquid. (Liquid)
Emergency Overview Reacts slowly with water to produce carbon dioxide which may rupture closed containers. This reaction accelerates at higher temperatures.
Inhalation at levels above the occupational exposure limit could cause respiratory sensitization and risk of serious damage to respiratory system. The onset of the respiratory symptoms may be delayed for several hours after exposure. A hyper-reactive response to even minimal concentrations of diisocyanates may develop in sensitized persons.
Potential Acute Health Effects
Eyes Hazardous in case of eye contact (irritant).
Skin Hazardous in case of skin contact ( irritant,sensitizer). Skin inflammation is characterized by itching, scaling, and reddening.
Inhalation Hazardous in case of inhalation ( lung irritant, lung sensitizer).
Ingestion Slightly hazardous in case of ingestion.
Medical Conditions Aggravated by Overexposure:
May cause or aggravate dermatitis and asthma.
General Information: Read the entire MSDS for a more thorough evaluation of the hazards.
3. FIRST AID MEASURES
Eye Contact - Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Seek immediate medical attention.
Skin Contact - Remove contaminated clothing. After contact with skin, wash immediately with plenty of warm soapy
water. If symptoms develop, obtain medical attention. Contaminated clothing should be thoroughly cleaned. An MOl study has demonstrated that a polyglycol-based skin cleanser or corn oil may be more effective than soap and water.
Inhalation - Remove patient from exposure, keep warm and at rest. Obtain immediate medical attention. Treatment is symptomatic for primary irritation or bronchospasm. If breathing is labored, oxygen should be given by administered by qualified personnel. Apply artificial respiration if breathing has ceased or shows signs of failing.
Ingestion - Do not induce vomiting. Provided the patient is conscious, wash out mouth with water. Obtain immediate medical attention.
Notes to Physician - Symptomatic and supportive therapy as needed. Following severe exposure medical follow-up should be monitored for at least 48 hours.

5. 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 clean with liquid decontaminant. Test atmosphere for MOl. 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-MOI is 5,000 Ibs (see CERCLA in Section 15).
Decontaminant 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'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.
6. 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 copper, copper alloys or galvanized surfaces.
Ideal storage temperature is 16-3SDC (60-100DF).
Keep stocks of decontaminant (See Section 6) readily available.
7. 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. 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.
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 MSHNNIOSH 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).

10. TOXICOLOGICAL INFORMATION
Toxicity to Animals LD50 Rat Oral: >5000 mg/kg
LD50 Rabbit Dermal: >5000 mg/kg
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 playa 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.
TOXICOLOGICAL INFORMATION>CONT
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.
Carcinogenic Effects The ingredients of this product are not classified as carcinogenic by ACGIH or (ARC 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 occupational limits.
Remark A study was conducted where groups of rats were exposed for 6 hours/day, 5 days/week for a lifetime to atmospheres 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 1 mg/m3 concentration, minimal nasal and lung irritant effects 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 adminsistration 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 concentrations leading to chronic irritation and lung damage, it is highly unlikely that tumor formation will occur.
