Full-Scale Experimental Evaluation of Fire Safety Distance of Straw Fireproofing Houses

Abstract:

Full-scale fire experiments were conducted to study the fire safety distance of novel straw fireproofing houses. Room temperatures, ambient temperatures and thermal radiation intensities were measured to analyze the behavior of straw fireproofing houses during the fire. The formula for the maximum outdoor thermal radiation intensities of straw fireproofing house at various distances was obtained by regression analysis, and this equation could be used to calculate the fire safety distance. It is found that the fire spread is significantly restricted by using straw fireproofing material. For the straw fireproofing houses, the fire safety distance is suggested to be 2.34 m. Furthermore, for the straw fireproofing houses under severe weather conditions with strong wind, the fire safety distance is suggested to be 2.51 m.
