ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance may be hazardous in the environment; special attention should be
given to birds and honey bees. This substance does enter the environment under normal use. Great care, however, should be given
to avoid any additional release, e.g. through inappropriate disposal.
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.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
