Someone at work got a new office. He decided he wanted a second door and tunneled through the wall to make it.

This wall was to the supply room with all of the uniforms and PPE. The building was constructed in the mid-20th century so it turns out it's full of asbestos. Thanks mole man.
On three separate occasions this past school year, some contractors were removing asbestos from one of the labs in the basement. The only notice was a paper sign posted very inconspicuously on two of the building doors, the day removal started.
They did some sealing on the hallway that room was in, but otherwise no precautions were taken. My office was two hallways down, and all classes in the building ran like normal. Very safe, very good
