Fire Suppression Guard

4 years ago, I was worried I might accidently break the glass retainer at my worksite emergency fire suppression. So, I designed this shield to protect against accidental use of the fire suppression. The guy who services our fire suppression system every 6 months has asked I make this file available as this is a commonly requested solution that is apparently not on the market.

I designed it with the intention of using white paint in the recessed lettering, though the one at my work has survived three fire marshal inspections and half a dozen service inspections with no one complaining about it.
