): The expected yearly strikes to a structure based on local flash density ( NGcap N sub cap G ) and building dimensions . Tolerable Risk ( NCcap N sub cap C

The Simplified IEC Risk Assessment Calculator (SIRAC) transforms a highly complex engineering standard into a practical, accessible safety tool. By accurately calculating lightning risks and simulating protective solutions, SIRAC ensures that structures are effectively shielded against atmospheric discharges while keeping engineering costs highly optimized.

Understanding the Simplified IEC Risk Assessment Calculator (SIRAC): A Guide to Machinery Safety

Elias nodded, closing the SIRAC window. The risk was still there, but now, at least, it was known. Simplified, but not ignored. ): The expected yearly strikes to a structure

: Instead of manual, multi-page calculations, the tool uses drop-down lists and simple input fields for building dimensions, allowing a basic assessment to be completed in just a few minutes. Core Parameters : It accounts for critical factors like: Structure Dimensions : Length, width, and height of the roof. Environment : Flash density (lightning strikes per k m squared

Several Malaysian universities, such as UTHM, have conducted competency courses to certify staff in the SiRAC methodology. ): Estimates the fire and thermal degradation risks

To generate a precise risk profile, SIRAC requires the user to input data across four primary categories: 1. Structural Dimensions

While originally proposed in the informative annex of the standard, the official SIRAC tool (v.1.0.0) was eventually phased out due to its inability to handle complex structures with multiple zones . However, the concept of a "simplified" assessment remains vital for identifying lightning risks without needing deep specialized expertise .

Can the operator get out of the way?

It is crucial to understand that is specific to IEC 62061 , which determines Safety Integrity Levels (SIL) . This differs from ISO 13849-1 , which uses a risk graph to determine Performance Levels (PL) .
