There are stark warnings from the Gas Safe Register about the risk of carbon monoxide poisoning from barbeques.
It is estimated that 3.7 million Britons will go camping over the summer holidays, but new research shows a lack of awareness of the potentially fatal consequences of inhaling noxious fumes from gas and charcoal barbeques.
In the last year, seven people have died and 17 have been seriously injured as a result of the issue.
Forensic scientist Roland Wessling lost his girlfriend, 31-year-old Hazel Woodhams, last summer after a camping trip to Great Yarmouth ended in disaster.
After extinguishing their disposable barbeque, they tidied it away inside their tent before zipping it closed for the night.
When Roland awoke in the morning he found Hazel dead and himself unable to move or remember where he was.
"I could hardly move, I had an extreme headache, was dizzy and dehydrated. When I checked on Hazel, I immediately realised she was dead... it was very difficult of course."
To add to Roland's horror the police suspect him of murder and arrested him in the ambulance as he was driven away from the campsite.
He said: "It was heart-breaking that anyone could think I would violate the woman I loved. Initially not even the police recognised that we had been the victims of CO poisoning. It was simply an avoidable, needless tragedy."
Roland was de-arrested a matter of hours later.
At Miss Woodhams' inquest the coroner, William Armstrong, said he hoped the incident would help to raise awareness.
But new research shows people remain ignorant of the dangers.
Sarah Hill, from the Gas Safe Register , says 20% of Brits are not aware that taking a gas barbeque inside a tent can lead to carbon monoxide poisoning and a third do not realise charcoal barbeques can do the same.
"There are warnings but people think it's about fire," she says.
But barbeques can be perfectly safe if used in the correct way.
Nick Price, from Go Outdoors , advises: "It's simple really. Barbeques should never be brought inside, even after they've gone out. If it's raining then you can use them under a well-ventilated canopy well away from anything flammable.
"For heat inside the tent use an electric heater. And if you're at all worried, buy a carbon monoxide alarm for your tent."
