France introduced new workplace heat regulations on July 1, 2025, mandating employer protections based on Météo-France heat alerts, according to the French Ministry of Labour. The reforms classify heat as a professional risk, requiring employers to adjust work conditions during yellow, orange, or red vigilance levels.
How Do Météo-France Alerts Trigger Employer Obligations?
Employers must monitor Météo-France heat alerts, which replace fixed temperature thresholds. During yellow alerts (intense heat for one or two days), orange (heatwave), or red (extreme heat), companies must implement measures regardless of local temperatures, per the *Journal Officiel de la République Française*.
What Are Employers Required to Provide?
Key obligations include:
- Providing at least 3 liters of free, cold drinking water daily per employee
- Maintaining indoor temperatures suitable for work activities
- Ensuring ventilation, using misters, fans, or sunshades
- Offering rest areas and additional breaks during heatwaves
- Adjusting schedules to limit outdoor work between 11 AM and 4 PM during orange/red alerts
These requirements align with guidelines from the *Institut National de la Santé et de la Recherche Médicale (INSERM)*, which emphasizes hydration and temperature management to prevent heat-related illnesses.
Which Workers Receive Additional Protections?
Vulnerable employees—such as pregnant individuals, elderly workers, those with chronic illnesses, or disabilities—must receive tailored precautions. Workers under 18 are prohibited from jobs exposing them to extreme heat, according to the *Code du Travail*.
Can Employees Refuse to Work in Extreme Heat?
The right to refuse work exists but requires evaluation of heat intensity, job nature, and employee health. Employers must assess risks before invoking this right, as outlined in *Le Monde*’s analysis of labor law updates.
What About Telework and Construction Workers?
Employees cannot demand telework during heatwaves; employers decide based on operational needs. However, construction workers (BTP sector) automatically qualify for “intempéries” unemployment benefits during orange alerts, per *France Info* reporting.
What Are the Penalties for Non-Compliance?
Employers facing heat-related violations risk fines up to €10,000 per affected worker, with penalties increasing to €30,000 and one year in prison for repeat offenses, according to the *Ministère du Travail*.
Workers experiencing heat-related violations can report issues to the *Inspection du Travail* or their company’s *Comité Social et Économique (CSE)*. The reforms aim to reduce heat-related illnesses, with 2,500 such cases reported annually in France, per *Santé Publique France* data.
