Topic Chemicals

More than 26,000 chemical substances are placed on the market in Europe in quantities above one tonne per year. Both the quantities produced and the number of chemicals being used are increasing worldwide. Potential undesirable environmental impacts must therefore be continuously assessed and, if necessary, regulated. Society expects everyday products not to pose any risks from harmful substances. International initiatives for more chemical safety also play an important role for Switzerland.

Requirements for specific uses

The Chemicals Risk Reduction Ordinance (ORRChem) is a basin for special provisions. These are enacted when the general provisions of the Chemicals Ordinance (ChemO) are insufficient. The ORRChem contains two appendices with restrictions and prohibitions for the manufacture, placing on the market or use of certain substances and preparations and articles containing them.
