| The paper analyzes the mechanism of fire happening and developing, the rules of spread, characteristic parameters, the cause and harm of fire, fire prevention and control etc. From the above analysis it can be seen that fire has the characteristics of the combination of static and dynamic states, the exchange from the static state to the dynamic one, and every phrase having its own factors accordingly. Based on the ignition of initial combustible material, the combustion of material around the initial one, the complete fire developing in the room, and the spreading out of the room, the building fire process is quadripartite. Analyze the factors about fire happening, spreading and causes of every phase. Based on the building fire hazards evaluation methods home and abroad, experts' discussion, and the building standards, define the value of every factor, and through the fire damage model and risk evaluation methods make the research on the danger of fire in every phrase. Evaluate the personnel abilities and management regulations as the compensation index. And based on the fire load density of the combustible and combustibility of decoration material, calculate the value of fire increasing modulus. Combining the building fire hazards partial period evaluation, compensation index and the fire increasing modulus, evaluate and grade the danger of the building fire. In order to decrease the differences caused by the diversity of personnel experience and knowledge, change the formal dot value to section one.The paper erects the safety system from the making and carrying out of safety rules, fire prevention regulations, and fire control according to different partial periods. Based on the characteristics of building fire and the demand of building management, the paper makes the building fire MIS and manages the building visually and dynamically.The application proves that the method is applied and meaningful. |
