|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.1 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).
MAK: (inhalable fraction): 0.1 mg/m3; carcinogen category: 3B; peak limitation category: II(2); pregnancy risk group: C; skin absorption (H); sensitization of skin (SH)
|The substance is very toxic to aquatic organisms.|
|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 with this substance.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The relation between odour and the occupational exposure limit cannot be indicated.
Rinse contaminated clothing with plenty of water because of fire hazard.
