Europe’s Heat-Stressed Workers: 130 Million at Risk as Record Temperatures Prompt New Safety Guidance

A Vienna bakery was reported to Austria’s labor inspectorate on 26 June after employees worked behind a counter at temperatures reaching 38 degrees Celsius when the air conditioning failed. The incident underscores a broader crisis across Europe: roughly 130 million workers are exposed to heat stress, according to a report released the same day by the European Trade Union Institute (ETUI).
That ETUI analysis, published amid a blistering heat wave, calculates that extreme workplace heat leads to about 277,000 injuries and 230 deaths every year. The damage goes beyond health. Each additional degree above the optimal working temperature of 16 degrees Celsius — identified by the ETUI — reduces productivity by two percent. In Central Europe, the resulting output loss ranges from 8 to 14 percent; in Southern Europe it climbs to 20–25 percent.
With extreme heat becoming a recurring workplace hazard, having a proper risk assessment process in place is essential. A free toolkit with 41 ready-to-use templates and checklists helps you document thermal risks and other hazards systematically, while keeping your business compliant with current regulations.

The economic toll is enormous. A study by Prognos estimates that a single hot day costs roughly 431 million euros. Those figures gain urgency as the German Weather Service (DWD) logged a new national record: 41.7 degrees Celsius in NeiĂźemĂĽnde, Brandenburg, the third consecutive daily record. Earlier, 41.3 degrees hit SaarbrĂĽcken on 26 June, followed by 41.5 degrees in Drewitz on 27 June.
New Heat Thresholds Go Beyond Temperature
The Federal Institute for Occupational Safety and Health (BAuA) has released the second part of its risk-assessment handbook, this time targeting thermal hazards. It provides precise burn thresholds for different materials, referencing standard DIN EN ISO 13732-1. For uncoated metals, the limit is 51 degrees Celsius for a contact time of one minute; with continuous exposure over eight hours, that threshold drops to 43 degrees Celsius.
The guidelines are not theoretical. The German Social Accident Insurance (DGUV) reported twelve new work-related accident pensions for burns in 2023. Experts are now calling for mandatory heat-risk assessments that factor in humidity and wind speed, not just air temperature.
Care Homes and Bakeries: Where the Heat Bites Hardest
Workers in nursing and care homes are especially vulnerable. The North Rhine-Westphalia Chamber of Nursing warns that many facilities lack air conditioning, with room temperatures frequently reaching nearly 30 degrees Celsius. In Thuringia, homes have resorted to strategic ventilation, extra breaks, and special drink offerings.
The German Association of General Practitioners (Hausärzteverband) on 27 June accused the federal government of failing on heat protection. It demanded the implementation of a measures package announced three years ago, plus reimbursed heat-protection consultations for medical practices.
Employers Get Help, but the Climate Keeps Shifting
For smaller companies trying to cope, the Wood and Metal Trade Association (BGHM) is offering a basic seminar on 1 July in SaarbrĂĽcken. Designed for businesses with up to 50 employees, it covers the Occupational Safety Act and how to create legally sound risk assessments.
Staying compliant with occupational safety laws as temperatures rise requires up-to-date documentation and risk assessments. The free Health & Safety Toolkit provides practical checklists, risk-assessment templates, and toolbox talks aligned with UK regulations to help you protect your workforce from heat-related hazards and other risks.

Meanwhile, the German Environment Agency (Umweltbundesamt) warns that climate zones are already migrating. Frankfurt am Main’s current climate matches that of Lyon in earlier years; by the end of the century, it could resemble conditions in Croatia. The Alfred Wegener Institute’s “Climate Extremes Atlas” shows the Saarland recording the sharpest temperature rise in Germany since 1881 — an increase of 2.1 degrees Celsius.
