The “Swiss Cheese” model is a visual way of demonstrating what happens to a Safety Instrumented System (SIS) and other Independent Protection Layers (IPLs) when not following the IEC61511 lifecycle and/or RAGAGEP (Recognized And Generally Accepted Good Engineering Practices) for the maintenance and mechanical integrity requirements. The “holes” in the Cheese represent a degradation of the SIS and iPLs created by random or systematic faults. These failures result in the “holes” appearing in our model and when all the “holes” line up, this is when the SIS and other protection layers fail to perform their risk reduction task resulting in an incident. This can then lead to severe consequences in terms of explosions, fires, toxic releases, etc.
The webinar ties in the Swiss Cheese model approach to the proper operation and maintenance requirements for the SIS and IPLs, which includes site culture, practices and competency.
