The European Chemicals Agency has submitted to the European Commission a recommendation that thirteen Substances of Very High Concern should in future not be used without authorisation. These substances are all classified because of their carcinogenic, mutagenic or toxic to reproduction (or a combination thereof) properties. They are used in applications where there is potential for worker exposure.

Making these thirteen Substances of Very High Concern (SVHCs) subject to authorisation seeks to ensure that their risks are properly controlled and that the substances are progressively replaced with suitable alternative substances or technologies.

These chemicals include Trichloroethylene, Chromium trioxide, and Ammonium dichromate.
