|The substance is very toxic to aquatic organisms. 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.|
|Do NOT take working clothes home.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
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.
Following the disappearance of symptoms from a short-term exposure, delayed effects could become manifest (after several days or weeks).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
