Abstract: Abstract This work identifies hazardous chemicals that cause chemical accidents in plants using simple and available properties. Particular attention is given to reactive chemicals and the relation between corrosion and accidents frequencies. The identification of hazardous chemicals is done by categorized ranking using the Hasse diagram technique. Hasse diagrams are the most promising method due to simplicity, wide use, and nonparametric advantage. To achieve our goal, the large number of isolated objects in Hasse diagrams was reduced/eliminated using a heuristic approach that presents strategies to speed up the ranking task. The basis is to collect suitable indicators and to define the suitable ranking objective. The ranking is presented using a case study of 22 chemicals with 8 simple hazardous indicators. Results show that the reduction of isolated objects is essential before evaluating the hazardous results. Also, simple and readily available data were used successfully as indicators for identifying chemicals causing accidents.
