In this episode, we welcome guest Curt Snyder, a certified functional safety expert. Wesley and Curt discuss ISA 84,  RAGAGEP prescribed by CCPS for the mechanical integrity element of SIS, while also referring to IEC 61511-1, which is a nearly identical standard. In this jam-packed, highly technical episode, you'll learn why these standards exist, their objectives, and then we'll provide a high-level walk-through of the SIS life cycle for a greenfield capital project.
