| 8.4.4 | Closet C
Centrally located in the building, potential wiring closet C is larger than either A or B. Its dimensions measure approximately 2.4 m wide x 2.4 m deep. There are five electrical outlets in the room. There are two along each side wall. One outlet is along the back wall. The floor is carpeted. Lighting is provided by a large fluorescent light fixture centered in the ceiling. Immediately outside the room, in the corridor, are two additional large fluorescent lighting fixtures. The switch that turns all three fixtures on and off is located on the wall just outside room C. There is no heating or cooling duct in the dropped ceiling space of this room, nor is there a heating or cooling duct into the room. The nearest thermostat for this section of the building is located in Room 120. The walls are concrete block construction covered with asbestos. Although the room has a lock, it can only be unlocked from the outside. Currently, the room serves as the mail room for the building.
