I was really shocked when I read that. They had used the bbq to warm up the tent and then left it outside the tent. The build up of carbon monoxide from that initial warm up was enough to kill him. We have one of these which I've used in the past to take the chill off for 5 or 10 minutes. I reckon next time I'll be taking a carbon monoxide meter with us just in case.
These products include malfunctioning fuel-burning appliances such as furnaces, ranges, water heaters and gas and kerosene room heaters; engine-powered equipment such as portable generators; fireplaces; and charcoal that is burned in homes and other enclosed areas.
Basically anything that burns carbon stuff (technical term ) can produce CO.
CO in a big plastic sealed (sig) tent = not a good environment for people to be in.
I agree with Mollie, if you are going to burn anything inside your tent, even if they are designed for the purpose then I would be getting a CO meter/alarm too.
Well we took heed and took a knife and fire bucket with us last week, will now be getting a CO alarm as well. Am also paranoid about getting eaten by grizzly bears but don't think you can get an alarm for that!!!
