An asset, system or barrier whose failure could directly contribute to a major accident or whose purpose is to prevent or mitigate such an event.
A Safety-Critical Element (SCE) is any asset, system, structure, component or barrier whose failure could cause or significantly contribute to a major accident, or whose purpose is to prevent, detect, control or mitigate the consequences of such an event. Safety-Critical Elements are identified through risk assessments and managed throughout their operational lifecycle to ensure continued integrity and performance.
Safety-Critical Elements provide essential protection against major accident hazards by preventing, detecting or mitigating hazardous events.
The concept of Safety-Critical Elements is widely applied within offshore and major hazard industries to support integrity management, performance standards and regulatory compliance for major accident hazard barriers.
A Safety-Critical Element is the broader asset integrity concept encompassing equipment, systems and barriers, whereas Safety-Critical Equipment refers specifically to the physical equipment designated as safety-critical.
