CMR classification / work with CMR substances

The Swedish Work Environment Authority's regulation AFS 2023:10, Chapter 8, states the rules that apply to carcinogenic, mutagenic or reproductive toxicants (CMR substances). CMR substances may only be handled if there is a documented investigation that shows that it is not technically possible to replace the product with other chemical products that are less harmful and thus pose less risk. Such an investigation may be part of the risk assessment that must be carried out before work begins. Workers who have been exposed to levels of carcinogenic and mutagenic substances that pose a risk to health must be registered (the business manager is responsible for establishing the register), and the information must be saved for 40 years.

CMR-classified chemicals are products with accompanying hazard statements

According to the CLP Regulation, CMR-classified chemical products are indicated with the following hazard codes:

• H350 may cause cancer,
• H340 may cause genetic defects, or
• H360 may damage fertility or the unborn child.

Risk assessment CMR work

The following information must be stated in the risk assessment:

1. which protective measures are necessary to minimize exposure,
2. in which situations personal protective equipment is required, and
   routines for maintenance and checking
3. the function of ventilation, and
   work and process equipment.
