Research on the Application of Fault Tree Analysis for Building Fire Safety of Hotels

Nowadays, in order to prevent large-scale casualties and significant property losses in the society, strengthening the building fire safety of hotels has become one of the hottest topics explored by more and more experts and scholars. In accordance with the building fire system analysis of hotels, considering the whole process of the fire accident, the fault tree of building fire was established. The analysis of relationship between the primary and secondary factors was conducted from three parts, the minimal cut set, the minimal radius set and the importance of structure. There are three main reasons for building fires in hotels, involving the personnel's unsafe behavior, the failures of electrical equipment and wiring as well as the ignition of flammable and combustible substance. And the key measures for prevention of building fires including strengthening the management of daily fire safety, key positions and key personnel have been proposed, which can improve the safety and operational reliability of hotel buildings. The analysis shows that the fault tree analysis method can make a comprehensive exposition of various factors causing fire of hotel buildings and their logical relations, which also provides a reference for the improvement of the design and the construction of the safety technical measures in other fields.
