2024 Spring Meeting and 20th Global Congress on Process Safety

(142c) How to Apply Ghs for Classifying Process Safety Events Via ANSI/API RP 754


The first 10 years of existence of ANSI/API RP 754, Process Safety Performance Indicators for the Refining and Petrochemical Industries (as adapted for general chemical sector), chemical hazard classification was based on toxic inhalation hazard (TIH), Department of Transportation (DOT), and United Nations Dangerous Goods (UNDG) measures. The third edition brought a new classification technique using Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This session explains the basis for development of the GHS option, comparisons of the original classification technique with GHS, and the practicality of applying the GHS option for classifying chemical releases. Hypothetical examples of chemical releases will be explored utilizing the GHS classification technique to better comprehend the tier level assignment.
