This webinar by Angela Summers will be a deep dive into the risk criteria used to evaluate whether process hazards are kept under control at acceptable levels.
Risk criteria help determine whether process hazards are controlled at levels consistent with societal expectations. When applied in process safety analysis, they turn regulatory intent into measurable engineering targets that guide the identification and verification of protection layers.
This presentation explores how single-scenario risk criteria provide a practical way to translate cumulative risk goals into engineering decisions. It explains how consequence severity influences acceptable event frequencies and provides a rationale for the criteria commonly used in LOPA.
