The UK is set to receive a longer and hotter-than-average summer after a May that’s seen both hot and dry temperatures and dreary rain1. A recent report highlights that around six million workers in the UK, particularly those in construction, agriculture, and logistics, are already exposed to working in extreme heat2.

Although some companies are able to close operations over hotter periods, some industries must continue on, so it’s important to know all the facts about staying safe working in a heatwave.
That’s why Nick Higginson, CEO at Phoenix Health & Safety, is sharing his expert insights into staying safe working in hot weather.

Nick explains, “It is up to an employee to alert their employer if they feel the temperature conditions make it an unsafe work environment. In the UK, there is no specific law that outlines a maximum working temperature, but employers have a general responsibility to ensure workplaces are safe. Whilst an employer has a duty of care for their employees, it is an employee’s responsibility to take the first action on any temperature concerns.”

How to stay safe working in the heat

1. Take regular breaks

Nick shares, “As temperatures rise, energy levels and concentration can be negatively impacted. The hotter weather forces your body to work harder to stay cool, so you may feel more fatigued, restless, and easily irritated.

“Taking regular breaks is a simple but effective way to improve your safety at work. If possible, look to take a 15-minute break every 2 hours or a 5-minute break every hour away from the sun. The time sacrificed is easily made up for through the improved quality of work and the minimised risk of long-term sickness.”

2. Rescheduling working hours

Nick shares, “The HSE, (Health & Safety Executive), advises that workers should try to try to reschedule outdoor work to cooler times of the day if possible3. The hottest part of the day is usually between 3pm and 6pm, but remember to keep an eye on the weather forecast to know for sure.

“If possible, try to complete your more taxing tasks in the morning or later in the evening, remembering to rest in shaded areas throughout the day.”

3. Hydration

Nick advises, “Keeping hydrated is a given in warmer weather, but it’s especially important when you are working in particularly hot conditions or exposed to the sun. When temperatures rise, our bodies sweat more to help us function. Drinking plenty of water is essential, but so is replacing the lost electrolytes.

“Try a recovery drink or low sugar energy drink alongside your two litres of water per day. If you don’t stay properly hydrated, your performance at work can be negatively affected, not to mention serious health conditions, including heat stroke.”

4. Protect your skin

Nick says, “It is really important to protect your skin when working outside, regardless of the weather. The hotter months bring an increased risk of burning, so it’s essential to wear SPF.

“Apply your SPF liberally before leaving the house and be sure to top up every two to three hours. Wearing a hat and sunglasses if possible can provide another layer of protection against the sun’s rays. Regularly inspect your skin for any unusual moles or spots, making sure to see a doctor if you see something unusual.”
