Dear Headteachers / Principals
We would like to alert you to a large fire on a land fill site in Cornwall and the plume cloud of smoke from it is coming over Plymouth. Our Civil Protection Team have advised that all schools especially those on the west of the city keep their windows closed as a precaution. We will keep you updated on the situation and will contact you again as soon as possible.
Many thanks for your assistance.
BBC News - Fire at private landfill site in Cornwall
SLT are now running around the site like headless chickens ensuring all windows are closed and that all students are pretty much locked inside.. just waiting for somone to sound the fire alarm now...
Do you have breathing apparatus training? :p
Don't envy you being shut inside on a hot day like today
If it gets smokey though, the AC will only pull the smoke from outside in....
Incorrect. It appears that you misunderstand how Air Conditioning works and are perhaps confusing this with a fan.

The air now less humid and the humidity of the room is reduced. Or or you could have cold coils that take the heat out of the air and expel it out the building.
Whichever method it uses, AC does no draw in external air so would be safe from the smoke.
