. struction with an average thickness of 2 ft. The total surface area for heat transfer is 5564 ft2 (see Attachment A for sketch and calculation of surface areas).

2. COMBUSTIBLE LOADING All cabling in this area is routed in conduit, there are no cable trays.

There are no combustible liquids in this area.

3. VENTILATION PARAMETERS There are three doors which enter this area. Two 3' wide by 7' high doors are located in the east wall and a 6' wide by 8' high double door is locatd in the west wall. ,
