The bulk update request #18786 has been rejected.
Propane tanks (40 posts) are gas cylinders containing propane. Utility alias because we cannot determine gas type inside all of their variants.
For laterally-standing fixed ones which are large and non-portable, there us tank (container).
There is also oxygen tank which is basically gas cylinder too. Should I include it into the alias, or keep it separate due to detailed usage context? (i.e. diving or hospitals). Nevertheless, it is the same thing too.
