LIFECYCLE ACTIVITIES FOR SAFETY INSTRUMENTED SYSTEMS IN AN ALUMINA REFINERY

With new requirements for instrumented protective systems in industry, many end-users are unaware of what this means to them and are treading carefully. New standards have brought new acronyms - SIF, SIS, SIL etc. to the table. The general understanding of these acronyms is not well understood and confusion surrounds which options an end user can or should take. Whilst recommendations are on offer from many consultants, their focus is generally on the design phase of the lifecycle. End users need to understand what installing a compliant Safety Instrumented System will mean to them, as compliance with a defined set of operational procedures is required to prove the ongoing integrity of the protection systems.
