Burn Cell 2 Diagram

Burn Cell 2 was the only room where an ignitable liquid (liquid accelerant) was present. It had a twin mattress laid on top of wooden pallets in the northwest corner, and wooden cabinets along the east and south walls. The floor was divided into quadrants: hardwood floor in the southwest, vinyl tile in the northwest, carpet with padding in the northeast, and bare 5/8” plywood subfloor in the southeast near the door. The room had a 4’x4’ window on the north wall, and a door and window on the south side. Approximately 90 oz. of ignitable liquid (paint thinner) was poured in the center of the room where the four flooring materials came together, and trailed onto the mattress and bedding material to the north.
