There was an especially fun example some years ago when I was conducting a representative of the Safety Office through the lab on an inspection. I'd checked everything before the inspection began, but when we got to the cold room we found a case of Sam Adams beer chilling on the floor. I was rendered speechless. The Safety rep didn't seem to know what to say either.
Who, who in their right minds would put their beer in the cold room when there's room in the coffee room fridge? I sent out an email to the whole lab informing them of what they should already have known: human food and lab hazards should be kept separate.
Well, it's happened again. This week a rep from Safety informed me that he'd found beer in the cold room. Corona this time.
So I sent out another email. "Beer in the cold room" I titled it, and in the email I admonished the unknown violator to remove his refreshments.
Now it comes to my attention that quite a few co-workers read my subject line and perked up. They thought it meant I was providing free beer for the lab!
I feel like such a wet blanket. :)
