ENVIRONMENTAL DATA
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT take working clothes home.
Also consult ICSC # 0341 ortho-Toluidine and 0343 para-Toluidine.
