Technical toluene diisocyanate is a mixture of 2,4- and 2,6-isomers (mostly 80:20).
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.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, 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 with this substance.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
No odour warning if toxic concentrations are present.
