Heat risk on construction sites rises sharply
On Tuesday, major trade unions across the European Union urged governments and employers to adopt stricter heat‑exposure rules after a surge in temperature‑related illnesses on construction sites and other outdoor jobs, citing rising summer temperatures that now exceed safe limits in many regions.
Union leaders say the climate emergency is turning ordinary summer days into hazardous work environments. Existing regulations often rely on voluntary measures, leaving workers vulnerable when temperatures climb above 30 °C. The unions argue that without legally binding limits, employers can ignore heat‑related risks to meet tight deadlines, endangering health and productivity.
In Italy, a construction worker in Perugia was photographed shielding himself with a portable sun umbrella while operating on an elevated platform. The image highlights how workers are improvising protection in the absence of formal safety standards. „We cannot expect workers to fend for themselves when the heat becomes a daily threat,” said Maria Rossi, spokesperson for the European Federation of Building and Woodworkers. Recent data from the European Centre for Disease Prevention and Control show a 40 % increase in heat‑related occupational injuries across the EU since 2020. The unions propose a mandatory temperature ceiling of 28 °C for outdoor tasks, mandatory rest breaks, and provision of cooling stations on sites. They also call for a legal right to refuse work when heat exceeds safe thresholds, without fear of retaliation.
Will new EU directives curb workplace heat hazards?
The European Commission is reviewing the proposal, but critics warn that voluntary guidelines have proved ineffective. „A binding directive would level the playing field and force all employers to invest in proper protective equipment,” argued Lars Jensen, head of the Nordic Workers’ Union. Some member states, such as Spain and France, have already introduced temporary heat‑risk protocols during heatwaves, but these measures lack consistency and enforcement mechanisms. If the EU adopts a unified standard, it could trigger a wave of upgrades to site infrastructure, including shaded areas, hydration points, and real‑time temperature monitoring. However, industry groups caution that stricter rules could increase construction costs and delay projects, potentially affecting housing supply.
The push for stronger heat‑stress protections reflects a broader shift toward climate‑responsive labour policies. As summer temperatures continue to climb, the unions expect that legal safeguards will become a non‑negotiable part of occupational health. If successful, the new rules could reduce illness rates, improve worker morale, and set a precedent for other climate‑related workplace hazards.
Frequently Asked Questions
What temperature limit are unions proposing for outdoor work? Unions suggest a legal ceiling of 28 °C for outdoor tasks, with mandatory breaks and cooling provisions when temperatures exceed that level.
How will a EU‑wide directive change current practices? A binding directive would require all member states to enforce uniform heat‑risk standards, eliminating reliance on voluntary measures and ensuring consistent protection across borders.
Are there examples of countries already implementing heat‑risk policies? Spain and France have introduced temporary heat‑risk protocols during heatwaves, offering rest periods and hydration stations, but these measures vary and lack a permanent legal framework.
