Polishing and sanding areas in schools

Hello to all I am sending this to,

I am doing some research on how schools and businesses have belt
sanders and polishing machines set up for ventilation and dust
collection.

Please let me know things like:

Does school have belt sanders and polishing machines in an enclosed
room or open shop area?

Is enclosed room exhausted to outside or to a dust collector?

Are dust collectors connected to machines?

What type of dust collector is being used?

Thank You for you assistance.
