PRIO – A tool for Risk Reduction of Chemicals

Introduction

This step by step guide presents a method for prioritising chemical substance risks in articles and products.

The method moves systematically through the inventory phase, hazard assessment and then the following prioritisation, which in turn leads to various measures to be taken.

The step by step guide is meant to be used as a support when you are looking for information about a chemical substance, which risks may be associated with that substance and what you can do to manage such risks.

  • Find out what substances are contained in a chemical product or article.
  • Assess the environmental and health properties of substances.
  • Prioritise which properties of the substance to which you should pay particular attention.
  • Review your risk picture.
  • Structure the work on replacing hazardous substances.
