Learning from a Barrier Deficiency: Maintaining Safety-Critical Equipment

This short animation shares the learning from a process safety event in which an Emergency Shutdown (ESD) valve was inadvertently left disabled following routine operations. While no incident occurred, the event highlights the importance of maintaining safety-critical equipment and effective barrier management.

The video explores the investigation findings and key lessons around procedural controls, human factors, visual management and equipment tracking. It reinforces the importance of maintaining robust barriers to help prevent process safety events.

Thank you to Repsol for sharing this learning with industry. By openly sharing experiences and lessons learned, we can strengthen barrier management, improve process safety and help prevent similar events across the energy industry.
