|OCCUPATIONAL EXPOSURE LIMITS|
TLV: (inhalable fraction and vapour): 0.001 ppm as TWA; 0.005 ppm as STEL; (skin); (DSEN); (RSEN); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued.
MAK: (vapour and aerosol): 0.007 mg/m3, 0.001 ppm; peak limitation category: I(1); (momentary value that should not be exceeded): 0.035 mg/m3, 0.005 ppm; pregnancy risk group: C; sensitization of respiratory tract and skin (SAH)
|The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment.|
|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 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.
