Since May 27, 2025, the law has changed to provide stricter protection for employees working in hot conditions. With summer approaching, this regulation marks a turning point for all employers in the construction, agriculture, logistics, and security sectors.
Heat waves and outdoor work: a public health issue
When temperatures exceed 30°C, the effects on the human body are immediate:
- Intense fatigue and decreased alertness
- Risk of workplace accidents
- Fever, migraines, cramps, dehydration, etc.
Heat waves are no longer the exception: they are becoming the norm. And in the face of this new climate, the obligation to prevent accidents is intensifying.
New PPE heat standard: what the May 27, 2025 decree says
Effective July 1, 2025, this new regulation requires employers to take concrete measures to protect their teams in the event of extreme heat.
The risks targeted:
- Deterioration of working conditions
- Accidents related to fatigue or inattention
- Illnesses: fever, cramps, heatstroke, concentration problems, etc.
Alert thresholds set by Météo-France:
- Green alert: seasonal monitoring
- Yellow alert: heat peak (1 to 2 days)
- Orange alert: prolonged heatwave
- Red alert: extreme heatwave (exceptional intensity and duration)
From the orange level onwards, enhanced measures must be put in place, particularly in the construction industry, where these periods entitle workers to compensation in the event of work stoppage.
What PPE is now recommended for heat?
The decree requires employers to adapt the equipment made available to workers:
Increased hydration:
- Provision of 3 liters of drinking water per day per worker in the absence of running water
- Installation of means to keep water cool near workstations
- Recommended PPE: insulated water bottle with a minimum capacity of 2 liters
Equipment to limit overheating:
- Choice of equipment to maintain a stable body temperature
- Recommended PPE: cooling neck protectors for helmets, cooling neck wraps (PCM or textile), cooling vests, cooling leggings
Protection against UV rays and solar radiation:
- Provision of UV and radiation protection PPE
- Recommended PPE: long-sleeved UV-protective T-shirts, technical caps or hats, sunglasses, SPF 50+ sunscreen
Information and training:
- Clear explanation of the risks associated with heat
- Training in the correct use of thermoregulatory PPE
- Awareness of the right actions to take in hot weather
