How much do your design and engineering practices contribute to minimizing common cause failures in Safety Instrumented Functions (SIFs)?

Common Cause Failure (CCF), often represented by the Beta factor in functional safety calculations, plays a significant role in determining the Probability of Failure on Demand (PFD) of redundant systems. Yet, reducing its impact goes beyond calculations. It also requires looking at how systems are designed, engineered, and maintained.

Join Pieter Poldervaart for the final session of his five-part SIS Mastery Series. We will explore what common-cause failure is, how it affects safety and availability, and why it can significantly influence the PFD of redundant systems. We will also look at how engineering practices can help minimize its impact and improve SIF reliability.

Warum sollten Sie teilnehmen?

Understanding common-cause failure is essential for making informed decisions about SIF design and reliability. This session will help you look beyond the Beta factor in your calculations and recognize how design choices and engineering practices influence the performance of redundant systems. Gain practical insights to better understand, assess, and minimize common-cause failure in your functional safety work.

Für wen ist dieses Webinar gedacht?

This webinar is particularly relevant for:

  • Functional Safety Engineers involved in SIF design and verification.
  • SIS Engineers responsible for safety instrumented systems and their performance.
  • Instrumentation and Control Engineers working with redundant architectures.
  • Engineering Managers and Technical Authorities overseeing functional safety practices.
  • Professionals involved in SIL calculations, PFD assessments and safety lifecycle activities.
