The simplified method uses several reduction and hazard factors to adjust the final risk score: Location Factor ( Cdcap C sub d
Lightning does not need to hit a building directly to cause damage. Strikes to connected lines can induce massive surges.
Despite its usefulness, SIRAC's journey was not everlasting. A major shift occurred with the publication of . In this draft of the updated German standard, a crucial note was added: "The simplified software for risk assessment for structures (Simplified IEC Risk Assessment Calculator – SIRAC) has been removed without replacement" . This same note is reiterated in the official German standardization documents.

SiRAC was developed by the IEC Technical Committee 81, Working Group 9, which was responsible for the risk management aspects of the new IEC 62305 series on lightning protection. The need for such a tool arose because Part 2 of this standard introduced a structured but mathematically rigorous method for managing risk.
SIRAC Tip: When in doubt, lean toward S2. Under-estimating severity is the most common cause of non-compliance.
While the original SIRAC tool is no longer supported, its core principles remain invaluable. Engineers performing a risk assessment to should follow these best practices:
Classification of areas where combustible dust hazards are present.
To appreciate the utility of SIRAC, one must understand the underlying standard it simplifies. IEC 62305-2 evaluates risk by identifying four primary types of loss: : Loss of human life (including permanent injury).
): Calculates direct financial damage to commercial operations, livestock, and localized equipment inventories. Step-by-Step Implementation Guide
A: No. "SIRAC" is a colloquial name for the simplified application of the IEC 62061 risk graph. The standard does not use the acronym, but the industry does.
The researchers applied both SIRAC and the TUPÃ tool to a heritage building in La Plata, Argentina. The goal was not just to get a final risk number but to compare how each tool handled the input parameters, what data entry options they offered, and how their partial and final results aligned with manual calculations based on the standard.
