Since the risk analysis is dependent on the estimated frequency and consequence severity of the hazardous event, the error associated with the consequence severity estimate directly impacts the estimated risk and ultimately the risk reduction requirements. Overstatement of the consequence severity creates excessive risk reduction requirements. Understatement results in inadequate risk reduction. Consistency in the Layers of Protection Analysis (LOPA) can be substantially improved by implementing consequence estimation tools that assist team members in understanding the flammability, explosivity, or toxicity of process chemical releases. This paper provides justification for developing semi-quantitative look-up tables to support the team assessment of consequence severity. Just as the frequency and risk reduction tables have greatly improved consistency in the estimate of the hazardous event frequency, consequence severity tables can significantly increase confidence in the severity estimate. 1 Process safety progress 31 ARTICULO Summers, Angela 52374 Vogtmann, William 52375 Smolen, Steven 52376 187025 187025 0 0 0 0 254844 BAAB BAAB 2026-03-06 200059130 0 200059130 2026-03-06 00:16:28 2026-03-06 ARTICULO
