Simplified IEC Risk Assessment Calculator (SIRAC)

Pitfall #4: Using SIRAC for Non-Control Risks

• Rely solely on SIRAC for high-consequence, low-frequency risks (e.g., catastrophic vessel rupture).
• Use without understanding that residual risk must still be evaluated qualitatively.
• Ignore the need for validation testing of the safety function (SIL verification).

Conclusion

Safety Conservative

: The tool typically uses conservative estimates to ensure safety, highlighting risk components in red if they exceed tolerable limits and green if they are safe. Risk Categories Evaluated

SIRAC is a screening tool, not a replacement for full risk assessment. It assumes ideal conditions and cannot capture complex interdependencies (e.g., multiple hazards interacting, unusual maintenance scenarios). For high-risk machinery (e.g., presses, robotics), a full, documented risk assessment per ISO 12100 remains mandatory. Conclusion Safety Conservative : The tool typically uses
