HSE updates guidance on working in cold and wintry weather

As winter approaches, the Health and Safety Executive (HSE) has updated its guidance for employers to help protect workers during cold and wintry conditions. This updated advice focuses on maintaining safe working environments, particularly for those working outdoors in challenging weather.

The guidance reminds employers that workers must not be exposed to cold temperatures for extended periods without appropriate measures in place. For indoor workplaces, the minimum temperature should be at least 16°C, or 13°C if the work involves strenuous physical effort. However, for outdoor workers, no minimum temperature is specified, but protection against the elements is required.

According to the HSE, it is the employer's responsibility to assess risks and provide a safe working environment. This includes providing heating, appropriate clothing, and ensuring that workers are regularly rotated or given breaks to warm up when working in cold conditions.

The updated advice also highlights the need for employers to ensure workers are properly trained on how to recognise signs of cold stress, which can lead to serious health issues if left unaddressed. Cold stress occurs when the body loses heat faster than it can produce it, leading to conditions such as hypothermia and frostbite.

"Employers should make sure workers have access to warm rest areas and provide suitable protective clothing when necessary. They should also take steps to reduce exposure to cold environments where possible," said an HSE spokesperson. "Simple actions, like scheduling breaks and providing hot drinks, can significantly improve comfort and reduce risks."

The HSE has also introduced a workplace temperature checklist to help employers carry out basic risk assessments. The checklist encourages employers to review issues such as air movement, humidity, and the use of personal protective equipment (PPE) in temperature extremes.

Employers are encouraged to assess the specific risks on their construction sites, especially as temperatures drop. This is particularly important for workers handling materials or machinery exposed to cold temperatures for long periods. In cases where the workplace temperature might be a factor in worker health, employers should consider providing additional support or adjustments to work schedules.

"Temperature management on site is crucial, especially for workers handling heavy materials or working outdoors," said the spokesperson. "By following these guidelines, employers can minimise the risks and keep their teams safe through the winter months."

For those working in particularly cold or hazardous environments, the HSE advises further consultation with workers to ensure that protective measures are adequate and that health and safety standards are being met.
