Pregnant and breastfeeding staff

In connection with pregnancy and breastfeeding, there are special issues to pay extra attention regarding the risks in the work environment.

Pregnant and breastfeeding staff are entitled to an individual risk assessment of their work environment.

The Swedish Work Environment Authority's provision on Pregnant and breastfeeding workers (see link below) regulates what kind of work may be performed by pregnant and breastfeeding workers.

The purpose of this provision is to prevent pregnant workers, workers who have recently given birth and workers who are breastfeeding, from being exposed to factors or conditions at work that may lead to the risk of ill-health or accidents.

See also the Swedish Work Environment Authority's theme page and other links and documents.

The following factors shall be investigated:

  • Load ergonomic factors
  • Psycho-social factors
  • Physical factors
  • Infectious agents
  • Chemical substances.

For instructions see “Supporting work environment document – Pregnant and nursing personnel in KI laboratories” under Documents below.
