In August 2020, a new restriction on diisocyanates was passed into law under REACH. This restriction applies to all products containing free diisocyanates in concentrations of 0.1 percent or more. It specifies both the need for mandatory training for all employees in handling such products and additional labeling requirements.
The comprehensive training program is available on an online platform that was officially launched on November 1, 2021 and can be accessed via www.safeusediisocyanates.eu.
