Safety instrumented systems play vital role in engineering processes

摘要

Equipping and managing industrial plant with the right components and sub-systems for optimum operational efficiency and safety is a complex task. Safety Systems Engineering (SSE) describes a disciplined, systematic approach, which encompasses hazard identification, safety requirements specification, safety systems design and build, and systems operation and maintenance over the entire lifetime of plant. The foregoing activities form what has become known as the "Safety Lifecycle" Model, and this is at the core of current and emerging safety related system standards.
