Ethanol pool fire phenomena were investigated in a real-scale enclosed space under limited ventilation by a blower at an exhaust vent. From the experimental result, unlike a general compartment fire, it was found that the enclosed space consisted of one layer, and there were extinguishing conditions under which fire was naturally extinguished by insufficient oxygen. The conditions were determined using an equation related to the amount of ventilation. Then, to carry out a computer simulation of fire with insufficient oxygen, we developed a method of determining analysis conditions. The analysis result obtained using a fire dynamics simulator (FDS) with this method agrees closely with the measurements.
