Study Emphasizes Employer Responsibility in Preventing Occupational Heat Stress

• Occupational heat stress must be addressed as an employer obligation and a collective labor issue rather than a matter of individual resilience.
• Preventive measures must be institutionalized and maintained year-round, regardless of current weather conditions, to mitigate the increasing vulnerability of workers to climate change.
• Economic data predicts significant losses in labor productivity across Europe, disproportionately affecting vulnerable workers and sectors.

Preventive Strategies and Management

• Holistic Risk Assessment: Evaluations must move beyond mere temperature readings to incorporate humidity, air velocity, and the heat retention of personal protective equipment (PPE).
• Essential Protocols:
  • Guaranteed hydration and access to cool rest areas.
  • Paid work-rest cycles and task reprogramming.
  • Enhanced ventilation and emergency planning.
  • Ongoing worker training and health monitoring.

Economic Impact and Risk Drivers

• The European Commission's Joint Research Centre warns that 22 European regions could face annual productivity losses exceeding 1% by 2050, potentially impacting 107 regions by the 2080s.
• Workplace vulnerability is dictated by job design, task intensity, precarious work arrangements, and the lack of collective bargaining power.

Vulnerable Demographics

• Higher-risk groups include migrants, platform workers, "false" self-employed individuals, pregnant women, older or younger workers, and those with chronic health conditions.
• Their heightened risk is exacerbated by limited access to labor rights, concentration in hazardous sectors, and systemic precariousness.
