Ding Dong..."why in Gods name would anyone with an ozs of common sense..want to use a Charcoal burner indoors...........o r maybe they do things differently in the US...like have BBQ,s indoors.. 
Now Bigwull, there is absolutely no problem with having BBQ,s indoors, ......
in West Virginia that is, ....... cause the rest of the world knows for a fact that most all of us Hillbillies live in houses that the wind blows right thru the cracks in the walls.
But on a more serious note, ..... natural gas (NG), kerosene and wood-burning appliances also pose
a similar and serious health threat if they are used
in a confined area of poor to no ventilization and/or the NG flame is misadjusted and not burning properly (a bright blue flame).
Ya gotta be smart enough
not to lock yourself up in the garage with your vehicle "running" .... or
not to lock yourself up in a small room with one of the aforesaid appliances "burning".
