  • Price Free of charge
  • Location Online: 09:00 GMT. Duration: 1 hour.


A Functional Safety Assessment (FSA) is an important review activity required by IEC 61511 to assess the functional safety achieved by a Safety Instrumented System (SIS). FSAs may be carried out at various stages of the safety life cycle, but as minimum must be carried out prior to hazards being present on a facility and also periodically during the operations and maintenance phase.

This webinar highlights commonly found issues from our Functional Safety Assessment (FSA) experience in the process sector and provides some recommendations for end users to prevent or mitigate these issues.

The webinar covers:

  • Introduction to FSA and the Functional Safety Standards
  • When to carry out an FSA
  • Commonly found issues at each phase of the IEC 61511 lifecycle
  • Key recommendations for end users

This webinar is aimed at plant managers; project managers; engineers of various engineering disciplines; safety managers.
