Using Quantitative Methods to Evaluate Process Risks and Verify the Effectiveness of PHA Recommendations

摘要

Federal regulations and internal factors mandate that mangers of chemical processes ensure that the process is operating in a safe manner. Traditionally, some form of a qualitative Process Hazard Analysis (PHA) has been used to evaluate the condition of the process, comply with federal regulations (specifically OSHA 1910.119 and EPA 40 CFR 68), and develop recommendations to ensure safe operation in the future. However, by extending what is required, actu- al process risks can be quantified, recommendations can be better prioritized, and money spent on safety can be allocat- ed appropriately.
