Fire tests were carried out for full scale semi-enclosed gasoline statio2 model. Two sizes of2fire source, gasoline as a fuel, of 600 1 in a 10 m and 900 1 in a 15 m pool were used. The burning continued about 8 - 10 min. Three locations of fire pool inside model compartment, at the end corner, middle position, and foot of the opening, were chosen with respect to the tank truck area. The results show that burning rate of gasoline at the end corner and middle position in semi-enclosure indicated 4.9 - 5.8 mm/min, and is 20% - 40% high compared to free burning. Gasoline vapor slided out on the floor by strong convection, and which gave an apparent bigger size of burning area. As the pool at the foot of opening chosen, this phenomena was clearly observed, then flaming tornado was performed as high as 18 - 20m and its burning rate was about 7.4 mm/min. This may be due to vortex initiated natural wind. Wired window glasses on the second floor, sometimes were touched with flame, were not broken even exposed to the heat flux of 9 W/cm 9 instantaneously.
