Where are building evacuation plans found? in a fireproof safe in bathroom stalls at the main entrance next to exit stairways

It should be in offices,the entrance doors to the building,elevators,desks,

You didn't give the options btw

That's  a project for you to do. btw your teacher probably uses a plagiarism detector and if you do copy anything on this site she/ he will find out and instead of getting a good  or bad grade you'll  get a 0 no exceptions, and they'll  probably call ur parents. so do some research ask friends and fam to you.
