Disposable barbecues are a "serious concern" for local firefighters, Staffordshire Fire and Rescue Service has said amid the latest heatwave.

The local fire service said the barbecues can pose a wildfire risk if they are left unattended or not disposed of safely.

The comments have come as several supermarkets including the Co-op, Morrisons, Sainsbury's and Tesco have all said they will stop selling disposable barbecues during the current dry weather due to concerns over wildfires.

Chief Fire Officer, Rob Barber said: "Disposable barbecues should never be used in the countryside and across popular beauty spots within the county. They can easily spread, especially in such dry conditions, and can quickly escalate into a dangerous and uncontainable wildfire.

"They should never be left unattended and should not be used when the person in-charge is consuming alcohol.

"If you do decide to use a disposable barbecue at home – ensure it is situated away from buildings, fences, trees or shrubs and make sure they are put right out and cooled before being thrown away.

"Grass fires can spread extremely fast so if you see dry grass smouldering, please call 999 and report it immediately."

An amber heat warning was issued for Staffordshire and most of the country over the weekend with temperatures reaching up to 33C.

A spokesperson for Staffordshire Fire and Rescue Service said: "Although anything that is burning can start a grass fire, common causes include carelessly discarded cigarettes or matches and rubbish left lying around such as glass bottles in direct sunlight. To reduce the risk of fire make sure your rubbish is safely thrown away and cigarettes are properly disposed of.

"Disposable barbecues are also a serious concern for fire crews as if they are left unattended or not disposed of safely they could result in a wildfire, especially when grass is tinder dry."

Firefighters are also warning residents not to cool off with a swim in open waters during the hot weather.

Rob Barber added: "Open water may look tempting but there can be lots of hidden hazards – It's usually deeper, colder and more dangerous than it looks. Even the strongest swimmers can get into difficulties, with a serious risk of cold water shock and drowning.

"Please take the time to talk to your children about water safety so that they understand the risks, look out for their friends and know what to do in an emergency. There is a range of helpful resources on our website."
