Improved fire and explosion index hazard classification

The Fire and Explosion Index (F&EI) is one of the most widely used hazard indices for chemical process plants. It was developed by The Dow Chemical Company in 1964 and has been improved, enhanced and simplified through the publishing of six editions. This paper describes the latest 7th edition and the improvements it contains. The F&EI is to serve as a guide for evaluating the hazard potential for separate major units of chemical process plants, is to aid in determining the consequences of a fire or an explosion and is to help determine appropriate loss prevention features to be used.
