Under § 5 of the Occupational Safety and Health Act, every employer must assess the hazards that the work brings for employees. The assessment decides which protective measures are needed. It is the Gefährdungsbeurteilung. A survey of the joint German occupational safety strategy found that the share of firms with such an assessment rose from 52 percent in 2015 to 68 percent in 2023/24. About a third of firms still have none.
