New Approaches for Calculating Safety Parameters and Estimating Hazard Severity for Cumene Hydroperoxide

Commonly used chemicals number more than four billion worldwide today, but an adequate understanding of the inherent properties of these materials exists only for several hundred thousands of them. Therefore, unexpected hazards or even accidents are difficult to avoid during preparation, transportation, manufacturing, storage and even disposal periods. Among these, hazards due to hydroperoxides can occur more frequently in various stages, with enormous resulting damage. As far as safety estimation is concerned, the basic safety parameters, unknown substance hazards and their severity need to be calculated and evaluated effectively. Screening methods are presented and validated to prove that they are viable approaches. Therefore, one of the responsibilities of a process safety engineer is to combine traditional approaches with modern computer techniques to develop a more thorough and convenient safety estimation model. Examples with cumene hydroperoxide are demonstrated.
