Join Angela Summers for our first SIS-TECH Townhall, where we bring key ideas from recent conversations into an open forum.

The January 9 townhall concerns "Understanding Risk Criteria: From Hazardous Events to Harmful Consequences." We’ll explore the logic behind our risk criteria, how they apply to hazardous-event and harmful-event assessments, and how they support consistent, defensible risk decisions. A concise, insightful session for anyone involved in operations or risk reviews. Come ready to share your thoughts and ask questions.

This webinar introduces the new features of SIL Solver Enterprise+ V2.7!

SSE+ V2.7 supports the different roles and responsibilities of personnel supporting the safety lifecycle, allowing you to control who can view or edit system data and who can add to or modify corporate-wide metadata.

SSE+ V2.7 covers the documentation requirements of IEC 61511 for safety instrumented systems and the impending requirements of ISA 84.91.03 for instrumented protection layers, such as safety interlocks, BPCS, IPL, Fire and Gas, ESD, and equipment protection.  

Key capabilities of SSE+ V2.7 include scope and hazard registries, document registry, Functional Safety Assessment (FSA), audits, process requirements specification, SIL verification, Safety Requirements Specification, Application Program Specification, and I/O lists.

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. 

This 4-day TÜV Functional Safety Engineer preparation course delivers a comprehensive, hands-on refresher on the ISA/IEC 61511 standard, equipping participants with the breadth of knowledge required for exam success.

The course goes beyond narrow expertise to provide a holistic understanding of the safety lifecycle—from hazard identification and safety requirements specification to design, implementation, operation, and maintenance of Safety Instrumented Systems (SIS). Participants will review essential terminology, functional safety planning, and updated risk assessment approaches such as LOPA and event tree methods.

Core topics include pragmatic development of the SRS, device approval pathways, design constraints for achieving SIL targets, and mandatory assurance activities across the lifecycle. The course also emphasizes real-world practices for sustaining SIS performance in operations, including managing bypasses, compensating measures, and change management. Supplemented by engaging exercises, attendees will practice critical skills such as allocating safety functions, applying SIL verification techniques, calculating PFDavg with Boolean and Markov methods, and managing lifecycle integrity.

By combining rigorous technical content with interactive application, this course provides an engaging and practical path to mastering functional safety and preparing with confidence for the TÜV certification exam.
