The System safety engineering Technical Network facilitates sharing and understanding of technical information and knowledge associated with System safety engineering for the benefit of IET members and the wider community. All of our events are open to members and non members and most are free of charge.
Welcome from the Chair
Welcome to the home of the IET System Safety Engineering Technical Network. We would love to hear from you about working with the TN and bringing forward any ideas to help us develop our network and contacts.
Technical Network Events
Each year the TN organises several topic events including seminars (F2F and online), webinars, and also engage with external stakeholder activities such and joint institutions events. Keep an eye out for Functional Safety to follow us.

Watch our on demand content: SIF Response Time Calculations – Are Your SIFs Fast Enough?
Safety Instrumented Functions or SIFs are only effective if they act quickly enough to prevent a hazardous event. Calculation of SIF Response Times is a critical performance parameter within SRS that can directly influence the risk reduction achieved from SIFs. The standards IEC 61508 and IEC 61511 require that the SIF Response Times must not exceed the Process Safety Time, that limits the maximum time allowed for a SIF to act.
This webinar aims to define the process for Process Safety Time and SIF Response Time Calculations, breaking the calculations into individual elements with a view to provide a structured, practical methodology that is aligned with IEC 61511. Participants will gain understanding of how to develop PST from worked examples and how to estimate SIF response time, built up from sensor, logic solver, and final element response times. The session bridges theory and practice, offering a practical workflow for calculating, validating, and documenting these parameters.
