TEROSON PU 9225 SF ME KOMP B BU

Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

Symptoms: Asthmatic-type symptoms may develop and may be immediate or delayed up to several hours.

Immediately flush skin with plenty of water (using soap, if available). Remove contaminated clothing and footwear. For severe exposures, get under safety shower after removing clothing, then get medical attention. For lesser exposure, seek medical attention if irritation develops or persists after area is washed. Wash clothing before reuse.

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.

Do not induce vomiting. Never give anything by mouth to an unconscious person. Get medical attention.

Foam, dry chemical or carbon dioxide.

High pressure waterjet

During a fire, MDI vapors and other irritating, highly toxic gases may be generated by thermal decomposition or combustion. At temperatures above 204.4°C (400°F), polymeric MDI can polymerize and decompose which can cause pressure build-up in closed containers. Explosive rupture is possible. Sealed containers at elevated temperatures or contaminated with water may rupture explosively. Water or fog may cause frothing which can be violent especially if sprayed into containers of hot or burning liquid.

Wear self-contained breathing apparatus and full protective clothing, such as turn-out gear.

Use personal protection recommended in Section 8, isolate the hazard area and deny entry to unnecessary and unprotected personnel. Evacuate and ventilate spill area; dike spill to prevent entry into water system; wear full protective equipment during clean-up.

For minor spills, absorb isocyanates with sawdust or other absorbent, shovel into suitable unsealed containers, transport to well ventilated area (outside) and treat with neutralizing solution: mixture of 80% water and 20% non-ionic surfactant Tergitol TMN-10; or 90% water, 3-8% concentrated ammonia and 2% detergent. Add about ten parts of neutralizer per part of isocyanate, with mixing. Allow to stand uncovered for 48 hours to let carbon dioxide escape.

Large quantities may be pumped into closed, but not sealed containers for disposal.

Do not allow product to enter sewer or waterways.

Remove all sources of ignition. Evacuate and ventilate spill area; dike spill to prevent entry into water system; wear full protective equipment during clean-up.

Materials: sawdust or other absorbent

Prevent contact with eyes, skin and clothing. Do not breathe vapor and mist. Wash thoroughly after handling. Exposure to vapors of heated MDI can be extremely dangerous. Protect from moisture. Keep container closed. Employee education and training in the safe use and handling of this compound are required under the OSHA Hazard Communication Standard.

Keep container tightly closed and in a cool, well-ventilated place away from incompatible materials.

Wash thoroughly after handling.

Store away from heat, sparks, flames, or other sources of ignition.

Stable under normal conditions of storage and use.

Not available.

Contact with moisture, other materials which can react with isocyanates, or temperatures above 204.4°C (400°F), may cause polymerization.

Keep away from heat, ignition sources and incompatible materials. Contamination with water.

Water. Alcohols. Amines. Ammonia. Strong acids and strong bases. Copper alloys.

Irritating organic vapours. Oxides of carbon. Oxides of nitrogen. Hydrogen cyanide. MDI vapors and aerosols. Isocyanates.
