FSA Checklist

Last Published: May 1, 2024

The FSA Background

As systems and processes involve ever more complex automation and software-base systems, functional safety standards have been extended to keep pace.

For compliance, you need to complete an IEC 61511 or IEC 61508 Functional Safety Assessment or Audit, and you're probably thinking "where do I start?".


The Challenge

It takes quite some considerable time to distil the contents of complex standards like IEC 61508 and IEC 61511 into a meaningful set of questions.


eFunctionalSafety FSA Checklist

The eFunctionalSafety FSA checklist contains more than 350 questions or prompts relating to standard IEC 61511 Functional Safety Assessment stages 1 to 4, including FS management and Audit questions.

Each question is cross-referenced to the applicable clause of IEC 61511 edition 2 and other standards where appropriate.

  • FS Management: 27
  • Hazard, Risk & SIL Study: 41

The FSA Solution for IEC 61511

The eFunctionalSafety FSA checklist is an original Microsoft Excel file to help you manage and report on the FSA process with virtually no startup effort.

A comparable development effort is estimated to be in excess of two to three person-weeks for an experienced functional safety professional with access to multiple functional safety standards and industry guidelines.
