In what circumstance is an additional justification required for Safety Instrumented Systems?

An additional justification is required for Safety Instrumented Systems particularly when lives are at risk due to the critical nature of safety in these situations. Safety Instrumented Systems (SIS) are implemented to mitigate hazards that could result in human casualties or severe injuries. Given that these systems are designed to prevent catastrophic events, any scenario where human life is at stake imposes a higher obligation on organizations to rigorously assess and justify the implementation of safety systems. This requirement ensures that the safety mechanisms in place are not just adequate but are critically appraised to bear the risk associated with life-threatening situations. It aligns with the fundamental principles of functional safety, which prioritize the protection of human life and the environment above other considerations.
