In Germany they recommend to use it only in well ventilated areas and suggest to refrain from using it indoors. I take this as itīs not considered save to do so.
There is a lot of truth in this,
caution is warranted,
burning produces carbon monoxide,
so you need to ventilate,
have stove on stable surface,
away from curtains ,
away from pets,
don't leave fire unattended,
don't drink alcohol or stuff like that,
keep children away from stove,
use carbon monoxide / smoke detector,
have fire extinguisher ready,
...
there is risk to everything
and the cheapest legal pants
![smile smile](/images/graemlins/default/smile.gif)
is to say don't take the risk at all
easier than convincing
people knowitalls to take precautions
but if you take a few simple precautions risk can be minimizedThis is what a book on wood/coal... cookstoves has to say about ventilation
Figure 20 - CO and average PM level reduction by ventilation
Closed Kitchen CO Average (ppm) 54
Hole in Roof CO Average (ppm) 18 reduction of 67%
Window and Hole in Roof CO Average (ppm) 14 reduction of 75%
Door Open CO Average (ppm) 1 reduction of 97%

Book also has a Cookstove Safety Ratings worksheet

burning produces emissions,
too much fuel burns more dirty,
pot sitting in flames produces more emissions,
