Thought Leadership: Live Barrier Model
A Practical Model for Making Safety-Critical Barrier Health Visible and Actionable
How Barrier Thinking, Performance Standards, assurance data, work processes and role-based competence come together in a Live Barrier Model.
From Verified to Live:
Making Barrier Health
Visible and Actionable
Periodic verification shows that a safety-critical barrier met its requirements at a particular point in time. A Live Barrier Model extends that assurance by connecting current maintenance, inspection, testing and deviation data to the barrier function and major accident scenario it supports. By linking Safety Critical Equipment, Performance Standards, assurance evidence, work processes and role competence, organisations can turn changing barrier conditions into visible, traceable and owned operational decisions.
