Using Layer of Protection Analysis (LOPA) for low demand scenarios in process safety applications is relatively straightforward. Recently LOPA is also being applied more and more to high demand and continuous mode safety functions as functional safety practices expand into machine automation. Using semi quantitative risk analysis techniques such as LOPA, can add a lot of value to high demand and continuous mode risk analysis. However, there are a number of potential issues which must be properly handled to avoid dangerous mistakes. This webinar will focus on how to correctly apply LOPA to high demand and continuous mode safety function risk analysis and manage these issues. The webinar will also provide guidance on how LOPA fits in with the requirements of the various safety standards and other risk analysis methods.
