Mechanism For The Upward Fire Spread Through Balconies Based On An Investigation And Experiments For A Multi-story Fire In High-riseapartment Building

Summary of experiments for the investigation of a fire which caused an upward fire spread for over 12 floors through balconies in a high-rise apartment complex is reported. The experiments include indoor tests to obtain fire properties of vertical PMMA fences and outdoor tests with a full scale model of the balcony. The test results suggest significance of the increase of total flame height through merging of flames and cooperative effect of the burning of PMMA fences and combustibles on the balconies for the generation of a tall flame enough to cause ignition on the upper floor.
