There are lots of chemical laboratories in high-rise R&amp;D buildings. Large amounts of hazardous chemicals were stored in them. Once a fire breaks out in high-rise R&amp;D buildings, its severity will be much greater than that of high-rise residential building fire. Inflammable chemicals, explosive chemicals, toxic chemicals are usually get involved in hazardous chemical fire. FDS software is usually used for numerical simulation of hazardous chemical fire. Then, the impact of hazardous chemicals fire in high-rise R&amp;D buildings can be analyzed under different fire conditions. This paper collected the hazardous chemicals stocks of 69 companies in the R&amp;D buildings and screened the storage data of hazardous chemicals. Typical hazardous chemicals were selected as fire simulation objects. The consequences of hazardous chemical fires can be analyzed by simulation results. The difference between hazardous chemical fire in R&amp;D high-rise buildings and residential building fire can be found out. At the same time, relevant performance indexes will be proposed for the evacuation of high-rise R&amp;D hazardous chemical fire.

Peculiarities of hazardous chemical fire in high-rise R&D buildings based on numerical simulation
