Let welders be refilled from fuel canisters.

[Vunterslaush]

because being able to empty them would make it too easy to secretly make chemthrowers, and most fuel cans irl have valves on the caps so they can't be just poured out.

being able to drink from them feels like a fair compromise

If you want to go full idiot, being able to drink from them and *spit while holding a lighter or match in your active hand should let you spit out a fire tile. Like breathing fire but with risk that you set on fire.

Anyway I still think the canisters should be useable for refilling welders.
