Abstract

In order to explore impacts of fire products on personnel evacuation in the event of a fire in buildings, relevant parameters of fire products were extracted through full-scale numerical simulation of building model, concept of personnel evacuation speed coefficient was introduced, and an evacuation speed model based on effects of fire products was established. Secondly, a new method to determine safe evacuation was put forward before numerical simulation was carried out for such evacuation considering impacts of fire products. Meanwhile influence of spray intensity and smoke exhaust rate on speed coefficient was analyzed. The results show that the proposed evacuation model can better reflect evacuation effects in the real fire site than traditional research methods. And addition of spraying and smoke extraction can effectively reduce impacts of fire products on evacuation speed. © 2020 China Safety Science Journal
