What do I have to note when implementing the measures?

Determine for the measures stipulated the priorities, deadlines and responsibilities. To effectively implement the requisite occupational safety and health measures, you should stipulate quite unmistakably:

WHO does WHAT by WHEN?

What documents can I use?

You don't have to start from scratch. Use, if available, the documents from risk assessments already conducted in the establishment. You can, for example, take over the list of hazardous substances, the substitute substances check and working instructions and refer to them in your risk assessment.
