| 8.4.3 | Closet B
Location B is slightly larger than location A. Its dimensions measure approximately 1.8 m wide x 1.5 m deep. Like location A, location B has a dropped ceiling. The floor is covered with ceramic tile. The walls are of concrete block construction covered by asbestos, which has been painted with a fire-retardant paint. There are no electrical outlets in the room. Lighting is provided by an incandescent fixture located in the ceiling; however, the switch that turns the light on and off is located on the wall across the corridor. 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 on an inside wall along the corridor. Currently, the room is used to store toxic cleaning supplies. The door swings outward when it is opened, and is approximately .9 m wide. Because it contains toxic materials, there is a lock on the door. The door can be unlocked from either inside, or outside, the room.
