Principle Routes of Exposure

Skin Contact, Inhalation of vapors and mist, Eye Contact Human Effects and Symptoms of Exposure: Acute Inhalation: Inhalation of vapors and mist of dicyclohexylmethane-4-4’-diisocyanate at concentrations above TLV can irritate the mucous membranes in the respiratory tract causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function. Person with pre-existing nonspecific bronchial hyperactivity can respond to concentrations below intended TLV may lead to bronchitis, bronchial, spasm, and pulmonary edema. These effects are usually reversible. Chemical or hypersensitive pneumonitis, with flu-like symptoms has also been reported. Diisocyanate vapors or mist at concentration above the TLV or PEL 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). Person with a pre-existing, nonspecific bronchial hyper reactivity can respond to concentrations below the TLV or PEL may lead to bronchitis, with flu-like symptoms (e.g., fever chills), has also been reported. These symptoms can be delayed up to several hours after exposure. These effects are usually reversible. 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 a later exposure to Isocyanate at levels well below the TLV. These symptoms can include tightness, wheezing, cough, shortness of breath, or asthmatic attack. These symptoms may occur immediately or up to several hours after exposure. Certain individuals may develop sensitization to diisocyanates (asthma or asthma-like symptoms) that may cause them to react to a later exposure to diisocyanates at levels well below the TLV or PEL. These symptoms, which can include chest tightness, wheezing, cough, shortness of breath or asthmatic attack, could be immediate or delayed up to several hours after exposure. Extreme asthmatic reactions can be life threatening. 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 or several years. Sensitization can be permanent. Chronic overexposure to diisocyanates has also been reported to cause lung damage (including fibrosis, decrease in lung function) that may be permanent. Acute Skin Contact: Dicyclohexylmethane-4-4’ –diisocyanate is a primary skin irritant—it reacts with skin protein and moisture and can cause irritation. Symptoms of skin irritation can include: redness, swelling, rash, scaling, or blistering. Discylohexylmethane-4-4’ –diisocyanate is also a potent skin sensitizer. Experience indicates that direct skin contact is the route of exposure most likely to cause sensitization. Once sensitized, an individual may react to even airborne levels below the TLV with the following symptoms: itching and tingling of the earlobes and neck, rash, hives, swelling of the arms and legs or other symptoms common to allergic dermatitis. These symptoms may be immediate or delayed several hours. Moreover, causes irritation with symptoms of reddening, swelling, and can cause sensitization. Persons previously sensitized can experience allergic skin reaction with symptoms of reddening, itching, swelling, and rash. Cured material is difficult to remove. Chronic Skin Contact: Prolonged contact with the Isocyanate can cause redding, 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 that respiratory sensitization may result from skin contact with dicyclohexylmethane-4-4’ –diisocyanate. Once sensitized, an individual may react to direct skin contact or even to airborne levels below the TLW with reddening, swelling, rash and in severe cases blistering and hives. These symptoms may be immediate or delayed several hours. Animal tests and other research indicate that skin contact with diisocyanates can play a role in causing isocyanate sensitization and respiratory reaction. This data reinforces the need to prevent direct skin contact with isocyanates. Acute Eye Contact: Liquid, vapors, and mist of this product are irritating and can cause tearing, reddening, and swelling of the eyes possibly accompanied by a stinging sensation. Irritation with symptoms of reddening, itching, and swelling can cause sensitization. Persons previously sensitized can experience allergic skin reaction with symptoms of reddening, itching, swelling, and rash. Cured material is difficult to remove. Chronic Eye Contact: Prolonged vapor contact may cause conjunctivitis. Acute Ingestion: Can result in irritation and possible corrosive action in the mouth, stomach, and digestive tract. May cause irritation; Symptoms may include abdominal pain, nausea, vomiting, and diarrhea. Chronic Ingestion: None found Carcinogencity: This product is not listed by NTP, IARC, or regulated as a carcinogen by OSHA. Medical Conditions: Aggravated by exposure: Skin allergies, asthma and any other respiratory disorders, eczema. 2. First Aid Measure: First Aid for Eyes: Flush with clean, lukewarm water for at least 15 minutes while lifting eyelids. Use fingers to ensure that eyelids are separated and that the eye is being irrigated. Then remove contact lenses, if easily removable, and continue eye irrigation. Refer individual to physician or ophthalmologist for immediate follow-up. First Aid for Skin: Remove contaminated clothing immediately. Wash skin promptly and thoroughly with soap and water. After washing, cover affected skin with polyethylene glycol and wash again immediately with soap and water to remove residue. Repeat if necessary. Wash contaminated clothing thoroughly before reuse. For sever exposures, get under safety shower after removing clothing. Seek medical attention if irritation or allergic dermatitis develops, or if gross exposure occurs. Fist Aid for 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 physician. 3. Fire Fighting Measures: Flash Point: 300 F Lower Explosive Limit: N.A. Upper Explosive Limit: N.A. Auto ignition Temperature: N.A. Extinguishing Media: CO2, Dry Chemical, Foam, Water, and Fog. Unusual Fire and Explosion Hazards: Combustible liquid – OSHA Class IIIB. Moisture contamination or exposure to excessive heat can cause polymerization to occur, during which heat and carbon dioxide are generated. Do not reseal contaminated containers; sufficient pressure may build up to cause sealed containers to rupture. “Empty containers retain product residue (liquid and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electrically, or other sources of ignition. Empty drums should be completely drained, properly bunged, and promptly returned to a drum reconditioner or otherwise properly disposed of. Closed container may forcibly rupture under extreme heat or when contents are contaminated with water (CO2 formed). Use cold-water spray to cool fire-exposed containers to minimize the risk of rupture. Larger fires can be extinguished with large volumes of water applied from a safe distance, since reaction between water and hot diisocyanate can be vigorous. Special Firefighting Procedures: As in any fire, firefighters should wear self-contained breathing apparatus pressure-demand (MSHA/NIOSH approved or equivalent) and full protective gear. Containers can build up pressure if exposed to heat (fire). Use water spray to cool containers exposed to fire conditions. 4. Accidental Release Measures: Steps To Be Taken In Case Material Is Released Or Spilled: Properly protected personnel (see section 6 for respiratory and other protection guidelines) should contain the spill. Floor may be slippery. Use care to avoid falling. i. Ventilate the spill area. ii. Prepare a decontamination solution of 0.2-0.5% liquid detergents and 3-8% concentrated ammonium hydroxide in water (5-10% sodium carbonate may be substituted for ammonium hydroxide). iii. Treat the spill area with the decontamination solution, using about ten parts solution for each part of spilled material. a. Allow to react for at least ten minutes. (Carbon dioxide will be evolved, leaving insoluble polyureas. b. Dike and collect water and residue for disposal. 5. Handling and Storage:

Storage

Temperature (Min/Max) 77 F (25 C)/ 122 F (50 C) Shelf Life: 6 months Special Sensitivity: If Container is exposed to temperatures above 122 F (50 C), such as a free fire situation, it can be pressurized and could possibly rupture explosively. Dicyclohexylmethane-4-4’ –diisocyanate reacts slowly with water to form CO2 gas. This gas can cause sealed containers to expand and possibly rupture explosively. Handling/Storage Precautions: Store in tightly closed containers to prevent moisture contamination. Do not reseal container if contamination is suspected. Do not breathe vapors, mists, or dusts. Use adequate ventilation to keep airborne isocyanate levels below the exposure limits. At maximum storage temperatures noted, material may slowly polymerize without hazard. Ideal storage temperature range is 86-104 F (30-40 C). Avoid contact with skin and eyes. Other Notes: If dicyclohexylmethane-4-4’ –diisocyanate is stored for prolonged periods at or below a temperature of 77 F (25 C), crystallization and setting of the isomer may occur. Storage in a cold warehouse can cause crystals to form. These crystals can settle to the bottom of the container. If crystals do form, they can be melted easily with moderate heat (e.g. in a well ventilated oven). It is suggested that a container the size of a drum be warmed for 16-24 hours at 104-122 F (40-50 C). When the crystals are melted, the container should be agitated by rolling or stirring, until the contents are homogenous. Since heated dicyclohexylmethane-4- 4’ –diisocyanate (104-122 F (40-50 C)) will generate vapors more rapidly than products at 77 F (25 C), be sure to follow the precaution under the Personal Protection Section of this MSDS whenever opening a heated container. 6. Exposure Controls/Personal Protection Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and safety shower. Good general ventilation should be sufficient to control airborne levels. Industrial Hygiene/ Ventilation Measures: Bayer strongly urges prevention of skin contact with all materials containing monomeric Desmodur W. Diisocyanate, including adducts, pre-polymers and formulations based on Desmodur W. Since spray application increases the potential for skin contact, stringent precautions must be taken to ensure the safety of the persons involved with the spray application as well as other persons working in the area who have potential for skin contact with the uncured material. For additional informatioin on Work/Hygiene Procedures, Skin Protection, Ventilation and Respiratory Protection Requirements, see Bayer’s booklet “Desmodur W. Aliphatic Diisocyanate Health and Safety Information.” Local exhaust should be used to maintain levels below the TLV whenever this diisocyanate is heated, sprayed, or aerosolized. Respiratory Protection: None normally needed. Because of the low vapor pressure of ISOCYANATES, local exhaust ventilation is usually sufficient to keep vapors below the TLV at room temperatures. Exceptions are when the material is heated or sprayed. If airborne concentrations exceed or are expected to exceed the TLV, use a positive pressure, self-contained breathing apparatus. Air purifying (cartridge type) respirators are not approved for Isocyanate vapors. A respiratory protection program that meets OSHA 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirator’s use. Skin Protection: The glove(s) listed below may provide protection against permeation. Gloves of other chemically resistant materials may not provide adequate protection. Polyvinyl alcohol VITON ® synthetic rubber (registered trademark of E.I. Du Pont Co.) Solvent resistant gloves. Where contact is likely, wear chemical resistant gloves and a face shield. Hand Protection Gloves should be worn, Nitrile rubber gloves, Butyl rubber gloves, Neoprene gloves. Eye Protection: Wear safety glasses with side shields (or goggles) and a face shield. Other Protective Equipment: Use chemically resistant apron or other impervious clothing to avoid prolonged or repeated skin contact. Testing of some commercially available protective clothing indicates that clothing constructed of butyl rubber, nitrile rubber, Saranex coated Tyvek and some neoprene garments have excellent resistance to permeation by ISOCYANATES. Clothing constructed of neoprene/latex rubber, some PVC garments, some polyethylene, and polylaminated Tyvek showed little resistance to permeation by ISOCYANATES. Protective clothing should be selected and used in accordance with, “Guidelines for the Selection of Chemical Protective Clothing” published by ACGIH. Hygienic Practices: Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid breathing vapors from material. Avoid prolonged or repeated contact with skin. Remove contaminated clothing and wash before reuse, wash hands before eating. Follow all MSDS/label precautions even after container is emptied because they may retain product residues. 7.
