A Method for Evaluating the Spatial Layout of Fire Stations in Chemical Industrial Parks

Abstract

The development of chemical industrial parks has resulted in the accumulation of a significant amount of hazardous substances, thereby increasing the demand for enhanced firefighting security, which directly relates to fire stations. This article presents a method for the layout evaluation of fire stations within chemical industrial parks. A practical technique for conducting fire risk assessments of each point to be rescued (PTBR) is proposed. The PTBRs are categorized according to their levels of fire risk. The required rescue time for each PTBR is determined based on the fire risk assessment. The estimated rescue times from each PTBR to each fire station are evaluated based on the actual road network and the speed of the fire engines. The adequacy of the fire stations is assessed through comparing the required and estimated rescue times. The working process of this method is illustrated using an engineering instance. The evaluation results of this engineering instance indicate its feasibility. This method takes into account the impact of irregular road paths and the influence of PTBR fire risks on the layouts of fire stations, which results in a more objective evaluation.
