Summer in the UK usually means one thing: heatwaves.
British summertime is long-awaited after our lengthy cold winters, and yet we never seem to be properly prepared for the inevitable heatwave (or heatwaves if we’re lucky).
This week the Met Office has issued its first ever red warning for heat with temperatures expected to climb to between 38C and 40C in some parts of the country.
But how hot does it need to be before workers should be sent home by their employers?
Here’s everything you need to know:
The guidance on workplace temperatures
Employers have a legal obligation to ensure that the temperature in the workplace is “reasonable”, as outlined by the Workplace (Health, Safety and Welfare) Regulations 1992.
Not only do they have a responsibility to maintain a suitable temperature for their employees, but it’s also their duty to ensure that the air is clean and fresh.
While there isn’t a maximum temperature for the workplace as laid out by the government, efforts have been made in the past to put one into place.
In 2006, the Trades Union Congress (TUC) released a briefing that highlighted the temperatures that it believes should be maintained in various workplaces as a matter of health and safety.
The TUC stated that it believes a maximum temperature of 30C should be set by employers, with a maximum of 27C put into place for those doing strenuous work.
The TUC added that employers should still aim to keep temperatures below 24C and note if employees express discomfort over the temperature.
The Chartered Institute of Building Services Engineers recommends a working temperature of 13C for those undertaking heavy work in factories; 16C for those doing light work in factories; 18C for those working in hospital wards and shops; and 20C for those working in offices and dining rooms.
The government has stated its recommended minimum temperatures for employees, with the Health and Safety Executive (HSE) recommending a minimum temperature of 16C for workers and 13C for those carrying out manual work under its Approved Code of Practice.
Despite the fact that a maximum temperature in the workplace hasn’t become legalised in the UK, there are measures that employees can utilise if they’re of the opinion that their workplace has become too hot to handle.
What to do if your workplace is too hot
The government recommends that employees speak to their bosses if the temperature in their workplace is uncomfortable.
According to the Advisory, Conciliation and Arbitration Service (ACAS), employers should carry out a risk assessment for the health and safety of their workers in order to determine whether the workplace is a safe environment in which to work.
The HSE states that employers must take six factors into account when assessing whether their workplace is a safe.
These factors are: air temperature, radiant temperature, air velocity, humidity, what clothing they wear and the average rate at which they work.
The HSE has created a thermal comfort checklist, which it recommends employers ask employees to fill out in order to determine whether they're experiencing thermal discomfort.
If a worker ticks two or more of the "yes" options on the checklist, then they could be at risk of thermal discomfort.
In this case, employers may need to carry out a more detailed risk assessment of the workplace.
It is ultimately up to the employer to decide whether the circumstances aren’t suitable for work.
However, it also depends on what kind of environment you work in.
If working outdoors, it’s the employer’s responsibility to introduce rest breaks for their workers and encourage them to hydrate regularly.
Furthermore, for those who typically wear business clothes to work, adopting a more casual dress code could prove essential for the overall wellbeing of employees.
What is Section 44 and how can you use it?
In circumstances where you think that you and your colleagues are in imminent danger, you may be able to turn to Section 44 of the Employment Act 1996.
The act states: “In circumstances of danger which the employee reasonably believed to be serious and imminent and which he could not reasonably have been expected to avert, he left (or proposed to leave) or (while the danger persisted) refused to return to his place of work or any dangerous part of his place of work.”
It continues: “In circumstances of danger which the employee reasonably believed to be serious and imminent, he took (or proposed to take) appropriate steps to protect himself or other persons from the danger.”
The first course of action is to raise any concerns with your employer or union, but Section 44 protects employees who wish to leave the workplace if they feel there are in imminent danger.
Here are some measures that employees can put into place to keep workplaces as cool as possible:
- Insulate exposed pipes that can become hot.
- Shade windows.
- Move workstations away from areas that are exposed to the sun or frequently become hot.
- Provide air conditioning or fans for employees.
- Provide thermometers so that workers can keep an eye on the temperature.
- Rotate workers if certain individuals are forced to cope with uncomfortable temperatures for prolonged periods of time.
