I make sure that wherever I sleep there are at least two exits, I make sure those are un-obstructed, I hate stoves that have their burners installed in such a way that they might vent CO2 into the surroundings. I don&#x27;t check for fire&#x2F;CO2 monitors because I would assume that even if they are present they&#x27;re not working. (Which, unfortunately seems to be the case more often than not.)
