With the rapid development of chemical process plants worldwide, the safe storage of hazardous chemicals continues to be an important topic. Chemical warehouse incidents related to fire and explosion are reported constantly. These incidents not only cause direct economic loss but also harm the local environment. Therefore, an accurate hazard identification method for a logistic warehouse is valuable since it can help people recognize the potential hazard in the chemical storage area. In this study, a storage hazard factor (SHF) was developed to evaluate and rank the inherent hazards of chemicals stored in logistic warehouses. In the calculation of SHF, the National Fire Protection Association (NFPA) hazard diamond was used to quantify the instability hazard; the U.S. Department of Energy’s Protective Action Criteria (PAC) values were utilized to modify chemical health hazard, and two machine learning based …
