Abstract

The invention relates to the technical field of fire fighting, and in particular, relates to a fire-fighting risk dynamic evaluation method. The method comprises the steps: acquiring fire-fighting risk indexes, wherein the fire-fighting risk indexes comprise a disaster-causing factor risk index H, a vulnerability index V of a disaster-bearing carrier and a fire-fighting emergency capability indexC; calculating a fire-fighting risk evaluation value R through the fire-fighting risk indexes; and obtaining a fire-fighting risk level corresponding to the fire-fighting risk degree according to thefire-fighting risk evaluation value R. According to the invention, the fire-fighting risk assessment value is calculated to obtain the fire-fighting risk grade, so that corresponding prevention and response measures can be taken according to the fire-fighting risk grade. According to the fire-fighting risk level, the center of gravity of fire-fighting work can be moved forwards from work such as fire extinguishing and rescuing treatment after a fire to work before the fire occurs, so that fire hazards are found in time, troubleshooting is conducted in time, precautions are made, and harm caused by the fire is reduced.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a dynamic evaluation method for fire protection risks. Background technique [0002] With the acceleration of industrialization, urbanization, and marketization, various super-large-scale industrial buildings and special civil buildings will emerge in large numbers, especially high-rise buildings, large underground buildings, and petrochemical flammable and explosive places. These buildings are huge in scale, complex in structure, and various disaster-causing factors increase, which increases the risk and complexity of fire, which in turn aggravates the damage caused by fire. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a fire risk dynamic assessment method, which provides technical support for fire response measures, thereby reducing the harm caused by fire. [0004] To achieve the above object, the ...
