While SIRAC established the framework for automated compliance, the evolution of the IEC 62305-2 standard eventually highlighted its limitations, leading the industry toward multi-zone enterprise solutions.
The Simplified IEC Risk Assessment Calculator represented an important step in democratizing access to complex international standards. By distilling the rigorous requirements of IEC 62305-2 into a user-friendly software interface, the IEC empowered a wider range of electrical engineers and building designers to conduct proper risk management for lightning protection.

Classification of areas where flammable gas or vapor hazards may arise.
The SIRAC tool is suitable for a wide range of organizations and industries that require IEC risk assessments, including:
After adding a light curtain, re-run SIRAC. The "Probability of hazard occurrence" (Pr) may drop, potentially reducing the required PL. Current door had a simple limit switch (PL
Because the risk assessment method described in IEC 62305-2 is mathematically intensive, involving dozens of parameters, the commission developed SiRAC to simplify the process. The purpose of the tool was to allow ordinary users to perform calculations for typical buildings without requiring deep expertise in the methodology. It is important to note, however, that the software was never meant to replace a full understanding of the standard, especially for more complicated structures where greater risks to life are involved.
Release is not expected to occur in normal operation, and if it does, it is infrequent and short-lived. 3. Ventilation and Dilution
As a simplified tool, SIRAC has distinct strengths and weaknesses, which were explored in academic research comparing it to more advanced software. The "Probability of hazard occurrence" (Pr) may drop,
The core utility of the SIRAC tool lies in its algorithmic simplification of the standard risk equations. While the full standard may require dozens of input parameters, SIRAC typically utilizes a "worst-case scenario" approach or conservative default values for less critical variables.
To keep the tool user-friendly, SIRAC makes several technical trade-offs:
