This is all a bit ott! when people have a bbq at home, with gas cylinders next to bbq, they may tell kiddie to keep away so as not to burn themselves. NOT incase there is a gas explosion!!!!
A properly connected gas bottle, with no leakage is safe for use imo, roofers etc use them all the time, carry them in their vans and never hear of their vans randomly exploding! Common sense prevails-keep van ventilated or flued while in use, turn gas off between jobs, and just enjoy the-albeit limited-benefits
