OPINION: A gas can is not a device, in my opinion.
A gas can connected to something or when lit with
a lighter and a reaction occurs; maybe in the broad
sense that total package might be considered a device.
Anyway, I hate to speculate out loud why the articles
vary to such a degree. I'm not an expert.
