One of the areas most affected by the occurrence of fires and explosions is the economy. These accidents lead to direct economic damages, which results in the withdrawal of capital for the reconstruction of damaged areas. In addition, there are other indirect economic losses, such as business interruption and reputational losses. The DOW Fire and Explosion Index (F&EI-DOW) is currently the most complete methodology for quantifying economic losses. Notwithstanding, the F&EI-DOW focuses on quantifying the hazardous potential of process units, and, does not provide an overall criterion for the hazardous potential of the entire industrial site with regard to: the inclusion of the so-called domino effect, the probabilistic risk assessment, the updating of existing risk analysis tools with new emerging Artificial Intelligence Techniques, and the quantification of reputation losses. For this purpose, the development of a new Fire and Explosion Economic Losses-Index (FEEL-Index) is proposed, which integrates the F&EI-DOW with new factors, such as the Damaged Area Factor, the Accident Probability Factor and the Reputation Loss Factor. With regard to the application to a case study, the total losses quantified by the overall FEEL-Index predict a value higher than the one predicted by the F&EI-DOW. The results obtained on an hydrocarbon storage case study show that the application of the FEEL-Index is relevant for increasing the risk perception, as well as providing guidance for prevention, mitigation, and risk management of accidents in process industries.

受火灾和爆炸影响最大的领域之一是经济。这些事故导致直接的经济损失，从而导致资金撤出用于重建受损地区。此外，还有其他间接经济损失，如业务中断和声誉损失。DOW 火灾和爆炸指数 (F&EI-DOW) 是目前量化经济损失最完整的方法。尽管如此，F&EI-DOW 侧重于量化过程单元的潜在危险，并没有为整个工业现场的潜在危险提供总体标准： 包括所谓的多米诺骨牌效应、概率风险评估、使用新兴人工智能技术更新现有风险分析工具以及量化声誉损失。为此，提出了一种新的火灾和爆炸经济损失指数（FEEL-Index）的开发，该指数将F&EI-DOW与受损面积因子、事故概率因子和声誉损失因子等新因素相结合。. 关于案例研究的应用，整体 FEEL 指数量化的总损失预测值高于 F&EI-DOW 预测的值。碳氢化合物储存案例研究的结果表明，FEEL 指数的应用与提高风险认知度相关，并为过程工业事故的预防、缓解和风险管理提供指导。
