UK households told to put A4 sheet of paper in fridge today

It's time to conduct a food-saving experiment

With this rather warm weather gripping the nation, British folk need to be careful with their refrigerated goods as the sweat-inducing weather continues.

With temperatures sitting at 30°C and warm weather set to continue into the coming days an expert is urging homeowners to do a little experiment involving A4 sheets of paper.

According to Beko UK's head of product management Salah Sun, per The Express, a common issue with old-ish kitchen fridges risks the loss of their edible contents during heatwaves like we're now experiencing.

If your fridge isn't brand-new, then the door seal will likely be looser than it should be and so it has to work a lot harder to remain cold.

Not only will this hike up energy bills, it'll also spoil your food much faster.

"One issue that may arise with your fridge is wear and tear on the door seal," said Salah.

"A worn-out door seal can prevent the refrigerator door from closing properly, causing the cooling system to work harder to keep your groceries fresh. This can lead to increased energy consumption and potential damage to your fridge and its temperature settings. Heat entering your fridge can overwhelm its cooling capabilities, especially during blazing summer days."

Salah went on to reveal a neat trick you can conduct.

"To check if your fridge door is functioning correctly, use a piece of paper. Place the paper against the door seal and close the door. When you try to pull the paper out, you should feel some resistance. If the paper slides out easily, your door seal may need replacing."

The UK Health Security Agency (UKHSA) recently issued a heat health warning for the entire country.

Those aged 65 and above, or anybody with pre-existing health conditions (such as respiratory and cardiovascular diseases) are at a higher risk in the current temperatures, with a "rise in deaths" forecast.

What are the rules on working in hot temperatures in the UK?

However while some readers may rejoice at the higher temperatures, it could pose some problems for anyone working over the next few weeks.

For commuters in London, for example, many of its features aren't equipped for warm weather, including several Underground lines.

Additionally, some of the capital's historic buildings and offices weren't built to stay cool and don't have the best circulation when temperatures rise.

So, it's safe to say you can count your blessings if you work in one of the city's more modern buildings.

Nonetheless, not all hope is lost if you don't, as bosses need to be mindful of office temperatures according to the Workplace Regulations set out in 1992.

Those regulations state that employers must legally provide a workplace with a "reasonable" temperature and good ventilation.

However, there is no minimum temperature or temperature limit for workplaces, meaning employers rather rely on recommendations than actual law.

According to the Approved Code of Practice, the lowest recommended temperature is 16ºC, or 13ºC when it's physical work, but there's no such guidance for other lines of work.

For that reason, it's more up to what your boss considers a "reasonable" workplace temperature.

Government considering rules on workplace temperatures

Although there are no current laws on workplace temperatures, Labour are reportedly considering making it illegal to work when it's too warm.

A new report from the climate change committee (CCC) recommended introducing maximum workplace temperatures, amid the risks of climate change to the UK.

The CCC's report said that by 2050, summer in the UK is predicted to be 'significantly warmer', with temperatures of 40C or even 45C expected to be seen in southern areas of the country.

“Maximum working temperature regulations would address the increasing risks that high temperatures pose to workers’ safety and incentivise the deployment of the necessary cooling," the report said.

"Businesses are largely responsible for investing in their own adaptations but must ensure that workplaces and working practices are safe for employees, including for those working outside.”

The CCC highlighted Spain as an example of a country with legal limits on temperature in the workplace.

Employers in Spain are responsible for meeting the requirement of 27C for sedentary work and 25C for light physical work, and if they fail to do so then employees can report them.

However, the workplace regulator Health and Safety Executive (HSE) are expected to stop short of introducing a legal maximum limit, in their development for plans of protections during hot weather.

Environment Secretary Emma Reynolds said the government will “carefully consider” the CCC's recommendations.

“We are acting to protect people and places from the impacts of climate change that are already being felt across the UK – from flooding to extreme heat and drought.

“Robust, independent science is essential and we will carefully consider the climate change committee’s latest recommendations to drive further action.”
