I suppose you know what you are doing, but high risk of explosion/fire with the fumes, that is why the original container usually have a correct seal, the beer bottles don’t. Twice treacherous: - For most gases, the stoechiometric proportion is very low (6-9% for methane — won’t ignite well above that) so it’s not like you have to keep a large quantity to be at risk, - Artist houses and painting schools often burn because rags are kept in a corner and self-ignite. Maybe not valid for you, maybe I’ve just heard horror stories ;)
