L78 Dipstick finish

[Unreal]

I was in a power plant 8-10 years ago, and I asked a guy who was removing some asbestos from a valve, to move his truck. He flipped me the keys and told me to move it. When I went to return his keys, he was inside the negative pressure tent installed around the valve. I held my breath and entered the double airlock doors. The guy was inside with his full-face air supply mask down around his neck, smoking a cigarette!!
