Recommendation: Use a vendor's free SIRAC tool for initial scoping. Use full SISTEMA for final certification. Several automation vendors now offer free online SIRAC

How often does a person enter the danger zone? Recommendation: Use a vendor's free SIRAC tool for

Fix: SIRAC must be applied to fault conditions, maintenance, and setup modes. A machine is most dangerous when guards are removed.

SIRAC is designed for risks mitigated by safety-related control systems. Do not use it for fire safety, electrical shock (non-control related), or chemical exposure. Use ISO 12100 for those.

Engineers often overestimate an operator's ability to escape. Human reaction time is typically 500ms. If the hazard occurs faster than that, Av2 is mandatory.
