So my new classroom is a converted cafeteria of the 1940βs βoriginalβ school. The boiler is right next to my room - and pipes burst last year, and instead of fixing them, they clamped them. So I need to listen for high-pitched hissing this year to see if they have any more problems in case it floods in the boiler room however, I am highly allergic to mold and mildew so now I am in a room with no official ceiling just a lot of exposed and wires (pipes on the ceiling from toilets above me that leak) and now have to worry about my health all year long.
