TLV: 0.05 mg/m3, ppm, as TWA; (skin); A4 (not classifiable as a human carcinogen); BEI issued.
MAK: (inhalable fraction): 0.1 mg/m3; peak limitation category: II(8); skin absorption (H); pregnancy risk group: D
|The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|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.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT take working clothes home.
