Thanks again Anh, in the mean time I think I discovered how to share
it via Google drive should the need arise again.

Yes I can quite understand the danger , we had a similar thing with
town gas in UK before changing to natural gas in the mid 60s.

The thing is with a whole wood fire the acrid pyrolysis offgas gives a
good warning of the flame having extinguished and there is unburned
carbon monoxide present  whereas with coal or charcoal  there is
little warning that carbon monoxide has escaped.
