Layer of Protection Analysis (LOPA)

This online course presents the Layer of Protection Analysis (LOPA) methodology used worldwide in the process industries for simplified, rule-based risk analysis. The course covers the basic LOPA approach to selecting and analyzing potential incident scenarios.

You will learn the finer points of topics such as enabling conditions and conditional modifiers, and the logistical aspects of planning and executing a LOPA study including documentation and program management. You’ll also gain CCPS guidance on initiating events, independent protection layers, enabling conditions and conditional modifiers - including the likelihood of ignition.

This course may be taken as part of the AIChE Credential for Sustainability Professionals (ACSP). More info
