| 8.8.6 | West building: first floor

The west building is located approximately 17 m. from the main building. Its dimensions are 40 m. x 37 m. A preliminary survey of the building has identified three potential locations for wiring closets on the first floor. They are marked on the floor plan as R, S, and T.

1. Location R is where the main power line enters the building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are covered with a fire-retardant paint. There are four electrical outlets in the room.
2. Location S is where the main water line enters the building. Water lines pass through the dropped ceiling space and lead to adjacent men's and women's restrooms. Like location R, this room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch for the room is just outside the door and to the right. The walls are of cinder block construction and are covered with a fire-retardant paint. There are three electrical outlets in the room.
3. Location T is near the front of the building. The room uses incandescent lighting. The door opens out of the room and can be secured with a lock. The light switch is to the left of the door upon entering the room. The room does not have a dropped ceiling. The walls are of cinder block construction and are covered with a fire-retardant paint. There are four electrical outlets in the room.
