So I got to work, and instantly noticed that the entire building smelled like death. I head over to the office to meet with the day crew to find out what the fuck is going on. Get told "A rat died gnawed into the piping back in the 4th closet, and died somewhere in the piping. We think it's closer to your side, but not sure." Lovely, I think. 70 year old building, this shit happens since they built em way different back then. Hell, I'm convinced our electrician was Canadian due to the weird ways the wiring was done through this bitch. So I get to work, changing out bulbs and ballasts, when all of a sudden I hear the fire alarm go off, and a rancid smell hits me 15 feet up in the air. I climb down the ladder and head into the hallway, only to be greeted by staff coughing and running for the exits. My boss had the bright idea to get the rat out by dissolving it with the most powerful sulfuric acid drain opener we could get from facilities. While, yes, it did work, now the building smelled like chemically cooked dead rat, and the drains in my section were smoking acrid smoke. And this was an hour into a 9 hour shift. Wound up spending a lot of my shift dumping water down the drains throughout the building to try and flush this shit out. Today sucked, yall, hope you had a good day though.
