TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Combustible. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames. NO contact with water.||Use powder, carbon dioxide.|
|EXPLOSION||Risk of fire and explosion as a result of decomposition when heated.||In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position.|
|EXPOSURE||AVOID ALL CONTACT!||IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Abdominal pain. Cough. Nausea. Shortness of breath. Sore throat. Vomiting. Symptoms may be delayed. See Notes.||Use local exhaust. Use breathing protection.||Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.|
|Skin||Redness. Burning sensation. Pain.||Protective gloves. Protective clothing.||Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness. Pain. Blurred vision.||Wear face shield or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Further see Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .|
|PACKAGING & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Collect leaking and spilled liquid in covered containers as far as possible. Treat remaining liquid with a mixture of ammonia (4-8%), detergent (2%), and water. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. If solid: sweep spilled substance into containers.||
Do not transport with food and feedstuffs.

Technical toluene diisocyanate is a mixture of 2,4- and 2,6-isomers (80:20), TDI is a common name.
Depending on the degree of exposure, periodic medical examination is suggested.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The odour warning when the exposure limit value is exceeded is insufficient.
Card has been partly updated in April 2005.
