Because SIRAC was removed from the later editions of the standard, engineers and safety professionals must now turn to other tools for their risk calculations. The most direct modern successor is the , particularly its DEHNrisk module. This browser-based tool allows users to perform risk analyses quickly and efficiently based on DIN EN IEC 62305-2 Edition 3 , representing the current state-of-the-art. Other general-purpose risk assessment software for functional safety, such as the PAScal Safety Calculator from Pilz, can determine Safety Integrity Levels (SIL) and Performance Levels (PL) for machine safety, though this serves a different segment of the risk assessment field.
The first edition of IEC 62305-2 was a monumental step forward in standardizing risk management for lightning strikes. However, it was also highly technical. To make the standard more accessible to a broader audience of engineers, architects, and safety inspectors, the standard's creators included SIRAC as a simplified implementation of the written methodology. simplified iec risk assessment calculator sirac
None. "It's been done this way for 10 years."
The tool sums the values for F, P, and AV to create a and then combines that with the Severity (S) to determine the required SIL ( SILrcap S cap I cap L sub r [Define Structure Dimensions & Location] │ ▼ [Input
): Adjusts the risk based on surrounding topography. Options usually include: Structure surrounded by higher objects. Structure surrounded by objects of the same height. Isolated structure with no other objects nearby. Isolated structure on a hilltop or ridge. 3. Structural Attributes and Contents
Due to these limitations, the official "SIRAC" version was omitted from the second edition of the IEC standard, replaced by more robust professional software suites. How the Calculator Worked (Example Scenario) This browser-based tool allows users to perform risk
Lightning strikes pose a severe threat to structures, electronic systems, and human life. To mitigate these hazards, the International Electrotechnical Commission developed the IEC 62305-2 standard, which provides a comprehensive framework for lightning risk management. However, full compliance with this standard involves complex, mathematically rigorous calculations that require significant time and expertise.
The number glowed red. The risk was fifty-two times higher than the legal limit allowed by the IEC standard.
