In most process plants Safety Instrumented Systems form one part of the overall risk reduction measures that companies deploy.
Today in both new and modified plants it is a legal requirement that the systems comply with the appropriate standards: ISA S84,ISO61508 and ISO6151.
The standards cover all systems that protect people, plant and the environment from hazardous situations and rate the required SIL (Safety Integrity Level) from 1 to 4 according to the requirement to reduce risk: RRF (Risk Reduction Factor). Understanding the standards and their application to hardware and Software design for such systems is crucial and it is essential to team with a ompany with this expertise.
