Something OCD in me is rather disturbed by the "release stench gas" being located to the right of the "anti-stench gas".

It should clearly (or likely) be the other way around, at least in any country with a left-to-right reading order, OCD or not :)

We scan information faster in the preferred reading direction, and flipping the warning​ gas on half a second earlier will likely, sooner or later save somebody from harm. Not that there aren't other ways to improve safety in mines, but each small part counts, I guess?

Not pictured, but right next to this machine is the "garry gum" and "anti-garry gum" dispenser.
