Key Highlights of the 30-minute Video:

  1. Roles and Responsibilities: There should be clearly defined roles within the team conducting the FSA.
  2. Importance of Leadership: One of the primary steps is to appoint a leader for the FSA. The leader plays a crucial role in planning and executing the assessment.
  3. Planning: Proper planning is essential for a successful FSA. A famous quote attributed to Winston Churchill is mentioned: "he who fails to plan is planning to fail."
  4. Assessment vs. Audit: The terms "assessment" and "audit" are both valid and slightly different in the FSA process.
  5. Legacy Systems: The FSA also affects legacy systems that are already in service in the process industry.
  6. Safety Instrumented System (SIS): The SIS is the focus of an functional safety assessment, but other steps are related to it, such as HAZOP and LOPA. Depending on the Safety Integrity Level (SIL), certain assessments might not be necessary.
  7. Human Error: The FSA is designed to detect human errors, as everyone is prone to making mistakes.
  8. Assessment Techniques: The FSA involves looking for evidence, which can include documents, databases, and verbal interviews.
  9. Compliance: Each IEC 61511 requirement is judged for compliance, which can result in full, partial, or non-compliant aspects.
  10. Experience: The speaker shares personal experiences and those of colleagues related to functional safety assessment.
