The janitors share an office with the boiler and generator in there. They probably have soem maintenance items in there like taken down fixtures, lamps, nuts and bolts, etc. There are also plenty of doors marked "COSTODIAL CLOSET" that are hallway-like rooms that contain breakers, fire extinguishers, wet floor signs, etc. When i can get some extra time, I'll get my notbook after school and copy a tag the best I can.
