A New Standard – Low Integrity Protection Layers
with Angela Summers
Next session: August 15th, 2025
A new standard, ISA 84.91.03, builds upon guidelines published in the CCPS LOPA, CCPS IPS, CCPS IE/IPL, and CCPS Safe Automation books, codifying them into a standard enforceable under process safety management regulations. Since the term BPCS is often confused with the control system, the new standard uses the term low-integrity protection layer (LI-PL) to cover any instrumented protection layer that is not expected to provide performance equivalent to a SIS but is needed to provide risk reduction. This new standard will significantly impact current industry practices, from identifying LI-PL during the process hazards analysis to monitoring their installed performance. This webinar will provide an overview of ISA 84.91.03 to raise awareness of the new standard's requirements and discuss its impact on typical process industry practices.
