Background
The SZW List (List of carcinogenic, mutagenic and reprotoxic substances) is a key instrument for compliance with the Dutch Working Conditions Act. Employers are required to minimize exposure to these substances. DOHSBase integrates the SZW List into the database so users can immediately see which substances are listed and which limit values apply.
