Rinse immediately with plenty of water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediate medical attention required.

Symptoms: Eye irritation.

Do NOT induce vomiting. Rinse mouth immediately and drink plenty of water. Do not give anything by mouth to an unconscious person or in case of convulsions. Immediate medical attention required.

Foam, Dry Powder, Carbon Dioxide, Water Spray.

None known.

Nitrogen gases, fumes/smoke, isocyanate, vapor.

Keep containers cool by spraying with water if exposed to fire.

Keep unnecessary and unprotected personnel away from the spillage. Clear area. Ensure adequate ventilation. Wear suitable personal protective clothing and equipment.

Absorb isocyanates with suitable absorbent material (sand, earth or any suitable adsorbent material). Leave to react for at least 30 minutes. Do not absorb onto sawdust or other combustible materials. Shovel into open container. Do not make container pressure tight. Move container to a well-ventilate area (outside). Wash the spillage area with water. Test atmosphere for MDI vapour.

If temporary control of isocyanate vapor is required, a blanket of protein foam or other suitable foam (available from most fire departments) may be placed over the spill. Transfer as much liquid as possible via pump or vacuum device into closed but not sealed containers for disposal.

Do not discharge into drains, sewers or watercourses.

Wash down spill area with decontamination solution. Allow solution to stand for at least 10 minutes. Dike spillage.

Prevent all exposure. Provide suitable exhaust ventilation at the processing machines. Ensure thorough ventilation of stores and work area. Provide eyewash station and safety shower. Avoid aerosol formation. When handling heated product, vapors of the product should be ventilated, and respiratory protection used. Wear respiratory protection when spraying. Danger of bursting when sealed gastight. Protect against moisture. If bulging of drum occurs, transfer to well ventilated area, puncture to relieve pressure, open vent and let stand for 48 hours before resealing. Take off immediately all contaminated clothing and wash it before reuse. Contaminated work clothing should not be allowed out of the workplace. Clean the equipment, workplace and clothing regularly. Do not eat, drink or smoke in areas where this material is handled and stored. Wash hands before breaks and immediately after handling. Protect from moisture and liquid. Moisture can produce carbon dioxide in the containers, causing high pressure inside the closed container.

Store properly and use within one year of the package date. Keep away from extreme heat and direct sunlight. Keep from freezing. Store at room temperature. Keep away from humidity and water. Store indoor, in a dry, well-ventilated area. Containers should be tightly sealed to prevent contamination with foreign materials and moisture.

Take off immediately all contaminated clothing and wash it before reuse. Contaminated work clothing should not be allowed out of the workplace. Clean the equipment, workplace and clothing regularly. Do not eat, drink or smoke in areas where this material is handled and stored. Wash hands before breaks and immediately after handling.

Danger of bursting when sealed gastight.

Ensure sufficient general and local ventilation. In addition to efficient general ventilation, well-functioning local exhaust is provided during high-risk work phases. Ensure that spaces designed to be vacuum remain pressurized. Preferably use tools with built-in local removal. Ensure proper maintenance of air conditioners. Replace the ventilation filters often enough for the air to change as planned. Ensure the adequacy of the replacement air and its correct orientation. Return air is not used in isocyanate work. Spraying work, such as coating, varnishing, open flotation, is carried out in the space provided or deliberately outside normal working hours so that other workers are not exposed unnecessarily. Automatic dispensers are recommended instead of taps and weighing whenever possible, and especially when isocyanates are used extensively. Measure and mix in a fume hood or in a well-ventilated, vacuum room.

Chemical protective gloves in accordance with EN 374 are always required for handling isocyanates. Used gloves are not caught on the outside and are not stored in your pocket. Multilayer plastic laminates can protect against exposure in all isocyanate work. In particular, they must be used in situations where the gloves are wet. Wearing a handy disposable glove on top of the laminate glove makes working easier. Glove materials suitable for 8 hours: thick nitrile rubber (thickness eg 0.9 mm with knitted lining), thick polyvinyl chloride (PVC, thickness eg 1.5 mm with knitted lining), Viton, butyl rubber, multilayer laminate (trademarks Silvershield and Barrier). Glove materials suitable for 4 hours: neoprene natural rubber (thickness of 0,7 mm or more). Gloves suitable for use for 1 hour: nitrile rubber gloves (thickness of 0,1 mm or more), natural rubber gloves (thickness of 0,5 mm or more).

Tightly fitting safety goggles (chemical goggles). Wear face shield if splashing hazard exists.

When a respirator is used as a risk management measure, it shall be selected so that the protective capacity is sufficient to reduce the respirable pollutants to less than 0,1 µg NCO / m³. The face of the mask should also protect the eyes. Only a compressed air hose device is well suited as an effective respirator. Protection devices: type 3A and 4A devices according to EN 14594. As these are difficult to install in all work sites, filter protectors with a fan are also used. TM3A2P class or TH3A2P class devices are recommended as a filter protector with a fan. The filter must be marked SL. The filter fills in use and it is not possible to smell the isocyanates, so the filter must be changed every day, unless the change interval can be estimated otherwise. If isocyanates are heated above 150 °C, the filter must be A2B2E2K2P SL.

Chemical protective clothing must be worn for work where isocyanates mass is splashed on clothing. The protective clothing must be a type 3 or 4 liquid-tight or splash-proof protective suit which, according to its chemical permeability table, protects against isocyanate and solvents. Isocyanates are absorbed into ordinary clothing and the skin is exposed through clothing. Exposure to bare skin must be prevented. Cover as much of the exposed skin as possible to prevent all skin contact. Suitable materials may include, PVDC-coated material, depending upon conditions of use.

Do not release into sewer, drainage systems, soil or water environment.

The product is stable if stored and handled as prescribed/indicated.

Corrosion to metals: No corrosive effect on metal. Oxidizing properties: Not an oxidizer.

Reacts with water, with formation of carbon dioxide. Risk of bursting. Reacts with alcohols. Reacts with acids. Reacts with alkalies. React with amines. Risk of exothermic reaction. Risk of polymerization. Contact with certain rubbers and plastics can cause brittleness of the substance/product with subsequent loss in strength.

Avoid moisture.

Acids, amines, alcohols, water, alkalines, strong bases, substances/products that react with isocyanates.

Carbon monoxide, carbon dioxide, nitrogen oxide, hydrogen cyanide, nitrogen oxides, aromatic isocyanates, gases/vapors.

The generation of waste should be avoided or minimized whenever possible.
