Dimensions: The 1-A-EPA fire area is approximately 3,658 sq. ft.; with a length of 63 ft., widthof 58 ft., and ceiling height of 23 ft. Assume natural ventilation with a vent opening of 3 ft. wideby 7 ft. high (a doorway). The cables of concern exited an MCC at about 10 ft. above the floor.Assume the fire starts in front of that MCC.

Analysis: 5 gallons of transient oil spill on 150 sq. ft. of rubber mat. Also present is 125 lbs ofsolid transient combustibles (poly bags, rags, rubber, wood). All get ignited by a portableelectrical implement (e.g., grinder, drill, heater, light bulb). Assume the rubber mat has a HRRof 354 Kw/sq. meter, an area of 17 sq. meters, and a total HRR of 6,000 Kw. Assume the 125lbs of solid transient combustibles have a HRR of 500 Kw/ sq. meter, an exposed area of 2 sq.meters, and a total HRR of 1000 Kw. The heat release rates from the rubber mat and the solidtransient combustibles are added to the heat release rate from the oil in analyzing the Hot GasLayer and Plume C/L Temperatures.
