NOTES |
---|
Technical toluene diisocyanate is either 100% 2,4- or a mixture of 2,4- and 2,6-isomers. TDI is a common name. CAS number of the mixture is 26471-62-5. Depending on the degree of exposure, periodic medical examination is suggested. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. 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. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. There is no odour warning even when toxic concentrations are present. See ICSC 0339. |
