The Department for Work and Pensions (DWP) has issued a fresh update confirming that the Health and Safety Executive (HSE) is reviewing potential amendments to introduce an upper temperature limit for workplaces. This comes as the UK braces for scorching temperatures, with the Met Office predicting peaks of 35C in southern England on Friday and Saturday, and humid conditions spreading northwards by the weekend.
Growing Calls for an Upper Heat Limit
The emerging reality of temperatures exceeding 35C in the UK has prompted growing calls for an upper workplace heat limit on health grounds, as is already the case in numerous countries. MPs have tabled parliamentary written questions to the DWP on the matter. Labour's Dr Peter Prinsley asked Secretary of State for Work and Pensions Pat McFadden: "If he will make an assessment of the potential merits of a mandated upper temperature limit in the workplace, including those working outside." Alex Mayer also questioned Mr McFadden on the potential impact of heatwaves on outdoor workers.
HSE Consultation Announced
In response, Sir Stephen Timms revealed that the HSE is reviewing potential amendments to regulations, with an announcement expected later this year. He stated: "The HSE is Great Britain's national regulator for workplace health and safety. There is a legal duty for employers to fully assess the risks to workers from extreme heat. HSE provides guidance for employers to manage the risk to workers, including from extreme heat. This year, HSE will also be launching a public consultation on proposed changes to the Approved Code of Practice for the Workplace (Health, Safety and Welfare) Regulations 1992, including those relating to workplace temperature."
Current Legal Requirements
During last month's heatwave, the HSE urged employers to 'act now' to safeguard workers. While no legal maximum workplace temperature exists, heat is regarded as a hazard and must be handled like other workplace risks. Employers are legally required to evaluate risks to workers' health and safety, including from severe weather such as heatwaves.
Practical Measures for Employers
John Rowe, Deputy Director for Technical Support and Engagement for the HSE, said: "Last summer should have been a wake-up call for all employers. If we continue to experience hotter summers this could have a big impact on the workforce of this country, affecting everything from health of workers to productivity on construction sites. The risks to workers from extreme heat must be properly assessed. Practical steps can include providing adequate ventilation and shade and allowing enough breaks for workers to cool down."
Simple measures recommended by the HSE include: ensuring workplace windows can be opened or closed to prevent hot air circulation; using blinds or reflective film on windows; placing workstations away from direct sunlight; insulating hot pipes and machinery; offering flexible working patterns; providing free drinking water; relaxing dress codes if possible; providing weather-appropriate PPE; encouraging removal of PPE when resting; and sharing information about heat stress symptoms.
