The UK Health Security Agency and the Met Office have issued a yellow heat-health alert The alert is the first to be issued in 2023.
HSE says this alert – and the record high temperatures seen in Great Britain last summer – should prompt employers to take action to protect those working both inside and outside in extreme heat.
There is no legal maximum temperature for workplaces but the regulator is calling on employers to be responsible, after seeing a ‘surge’ in people seeking advice during summer 2022, when temperatures exceeded 40oC for the first time in history.
Employers must assess risks to the health and safety of their workers by law, including risks from extreme weather such as heat waves. While there is no legal maximum temperature for workplaces, heat is classed as a hazard and should be treated like other hazards.
HSE says everyone – whether working indoors or outdoors – is at risk and employers should discuss with workers changes to manage the risk.
