PRIO – A tool for Risk Reduction of Chemicals

Prioritisation levels

All the substances in the database have been allocated a prioritisation level; phase-out substance or priority risk-reduction substance. The prioritisation level indicates how you should act, how highly you should prioritise the substance in your risk-reduction work. The assessment has been made according to the "worst" properties of the various substances, as a carcinogenic phase-out substance may, for example, also have properties that belong to the priority risk-reduction level (e.g. allergenic). Each substance is accompanied by a "message" that varies according to what prioritisation level it belongs to, as follows:

Priority risk-reduction substance

Because of the hazardous properties of the substance, it is particularly important to consider how the substance is handled.

Assess the risks for the intended use.

Consider substitution!

Some of these substances are prohibited/restricted in Sweden.

Phase-out substance

The following applies to most phase-out substances:

This is a substance with properties of particular concern.

The environmental quality objective "A Non-Toxic Environment", adopted by the Swedish parliament, requires that the use of particularly hazardous substances shall cease to the extent possible.

Some of these substances are already prohibited/restricted in Sweden.

In the EU legislation Reach, these substances may become subject to an authorisation procedure.

Where complex hydrocarbons are concerned, there are exceptions in some cases to the call for phase-out as they avoid classification as carcinogenic under certain circumstances. Read more about this in KIFS 2005:7.

Ozone-depleting substances are subject to their own environmental objective and they therefore have a "phase-out message" that has been adapted accordingly:

This is a substance with properties of particular concern.

Use of the majority of ozone-depleting substances is prohibited in Sweden. There are a few exceptions, e.g. for laboratory work.

According to the environmental quality objective "A Protective Ozone Layer" concentrations of chlorine, bromine and other ozone-depleting substances in the stratosphere do not exceed natural levels.
