Thom,
CO detectors are inexpensive; I keep one in my cabin (I have a propane
burner and lantern).
I guess the CO2 could be problematic if the levels rose too high, but at
least it's non-toxic.
"Alcohol heaters consume oxygen. As O2 levels in an enclosed space fall,
fuel is incompletely burned and carbon monoxide is produced. A clue this
is happening is that a normal blue flame becomes yellow and smoky."

enough to vent in cold winter air. I could use some useful comments?

My galley has a twin Origo range. I fire a single burner off of
non-pressurized alcohol to perk my morning coffee. I return to the
sleeping bag and enjoy the aroma of perked coffee and the stove warming
the "Pilothouse"

I get up and dress in a sweat suit and fleece lined slipper and fire off
the other burner for home fryed potatoes with onions and remove the
coffee pot to make eggs on the other burner; still with a cloesd cabin.

As the cabin warms up I vent the main hatch, and have my second cup of
coffee.

So, how much terrible am I playing with.


Get a Carbon Monoxide monitor. It will tell you when to vent. I have
them in all cabins.

BTW a lady across the lake caught herself on fire filling her alcohol
stove last week. She could not see the flames,once she felt it burning
she tried to drop and roll but did not have enough room on her galley
sole. She ended jumping in and her skin fell off. They life flighted
her to the hospital. She claimed the stove was cold when she tried to
fill it.

Be careful!

I use the microwave.
