Understanding real-time barrier health management
Since publication of the U.S. Occupational Safety and Health Administration’s (OSHA) process safety management (PSM) standard in 1992, awareness around process safety has grown exponentially. Other countries have taken a different approach, but all have aimed at the same outcome “to reduce, and ultimately eliminate, fatal and high severity process safety events.”
Particularly in industries with a high hazard potential, organizations want to know how activities, both direct and indirect, affect their process safety management status. Companies in less risky industries are also interested in the lessons learned from facilities that have implemented robust safety management systems encompassing PSM elements.
At the Hazards 34 process safety conference this past November in Manchester, U.K., one critical topic of discussion was the use of PSM-enabling digital tools such as digital twins. By providing a virtual representation of a system, a digital twin delivers an enterprise-wide understanding of how planned work activities impact process safety barrier and equipment health.
The virtual system makes risk exposure visible in real time, reducing vulnerability to high-potential near-misses and major hazard events. Such digital tools serve to provide unmatched clarity into how operational activities influence the overall safety landscape.
