Red Heat Warning Prompts Scrutiny of UK Workplace, School Temperature Guidelines
A rare red warning for extreme heat has been issued by the Met Office, covering significant areas of England and Wales from Wednesday at 09:00 until Thursday at 21:00. Forecasters predict temperatures could reach 40C, prompting concerns over public safety and operational guidelines for schools and workplaces.
Schools Grapple with Extreme Heat Conditions
Despite the severe weather alert, there remains no statutory maximum temperature for classrooms in the UK. The government maintains that schools can typically manage safely and advocates for sustained attendance. Teaching unions, however, have recommended schools aim to maintain indoor temperatures at a maximum of 26C. Head teachers are expected to conduct risk assessments, monitor pupils for signs of heat-related distress, and may consider altering uniform policies, adjusting school hours, or relocating lessons to cooler areas. The UK Health Security Agency (UKHSA) advises against using fans if temperatures exceed 35C. Union bodies have reiterated calls for government investment to enhance the climate resilience of school infrastructure.
Workplace Safety Under Review Amid Rising Temperatures
The UK also lacks a legal maximum workplace temperature. Health and Safety Executive (HSE) guidance stipulates employers must ensure 'comfortable' working temperatures and 'clean and fresh air'. Acas, a workplace advisory group, suggests that closing workplaces due to heat should be a 'last resort in extreme circumstances'. Niall Mackenzie, Acas chief executive, emphasised the need for employer flexibility, including relaxed dress codes, increased breaks, and provision of cool drinks. Last month, the Climate Change Committee (CCC) advocated for the introduction of a maximum workplace temperature to safeguard employees as heatwaves intensify. For outdoor workers, the HSE recommends rescheduling tasks to cooler parts of the day, providing shaded rest areas, and ensuring access to cool drinking water. Transport services are also anticipated to face disruption, with National Highways advising drivers to carry ample water and consider altering travel times.
