My New Jobs Threat Levels

Even though the picture isn't the best, I thought I'd show off my new jobs threat levels.  These are not threat levels of amount of workload, stress levels, or anything like that.  Instead it is a gaseous methane vapor monitoring system.  Today I was lucky, it was a blue air condition day.  As apposed to a brown or double brown diamond day.  The last symbol means they had Qdoba.
