Also centrally located in the building, room E is adjacent to the POP. Room E is smaller than room D. Its dimensions are approximately 2.4 m wide x 1.5 m deep. A water pipe enters the building through room E, and travels from there to other locations throughout the building. There is also a hot water heater in room E. In spite of repeated attempts to remedy the problem, the water pipes in room E are heavily corroded. There is no false ceiling in the room. The floor is covered with ceramic tile. A heating and cooling duct that passes through the top of the room is also vented into the room. The nearest thermostat is located in the corridor outside the room. Lighting is provided by an overhead incandescent light suspended from the ceiling. The switch that turns the light fixture on and off is located just inside the door to room E. The door, which is approximately .9 m wide, swings into the room when it is opened. There are two electrical outlets in the room. They are located on opposite walls. Because of its contents, room E is kept locked, and can be unlocked from either inside or outside the room.
