PRIO – A tool for Risk Reduction of Chemicals

Differentiate between hazard and risk

When you choose to use a particular chemical, the associated risks should be decisive for the assessments you do. A risk consists of two factors, first the inherent properties the chemical has: hazard, and also the way in which the chemical is used or handled: exposure.

PRIO can be used to identify hazardous properties of chemical substances. Different properties give rise to different risks in different situations. Those who make the assessments must therefore include information on how the substance is used or handled for the decision-making basis to be complete.

It is important to be aware of the risk to which the substances can give rise to and to decide how to manage any risk. Continuing to use a risk-reduction substance may be a solution if the function the substance fulfils causes the lowest overall impact on health and the environment from a product.
