From PHA/LOPA to SIL: Translating Risk Analysis to SIL Selection & Verification

Charlie Souza, Functional Safety & ICS Cybersecurity Lead

This webinar explores how PHA/LOPA results should inform SIL selection—and how SIL verification confirms that SIS performance matches the intended risk reduction. For many PSM leaders, these activities are closely related yet not always clearly connected in practice. This session will translate the relationship among scenario risk ranking, target risk reduction, SIL selection, and SIL verification into plain language and explain why a high PHA risk ranking does not automatically mean a high SIL. Watch to understand how better alignment between risk analysis and functional safety decisions can improve consistency, defensibility, and decision quality across your PSM program.
