Notice:
California Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals.
METTLER TOLEDO is providing this warning based on its knowledge that one or more chemicals listed by the State of California in connection with Proposition 65 may be present in METTLER TOLEDO products.
These and other Proposition 65 chemicals may be present only in trace amounts, or contained internally in METTLER TOLEDO equipment, or encapsulated in another material where exposure is unlikely or negligible. This warning is being provided out of an abundance of caution. |
This web page is intended to give METTLER TOLEDO institutional customers information needed to ensure their workplaces are compliant with the requirements of California Proposition 65, and should not be relied upon as a statement of what specific chemicals or materials may or may not be present in a particular METTLER TOLEDO product.
