Helps meet the requirements of the Machinery Directive (e.g., 2006/42/EC).
While the original SIRAC is largely historical, its legacy lives on in modern tools: Applying the New Trends in Lightning Risk Assessment

As structural engineering advanced, the limitations of SIRAC prompted developers and standard agencies to create multi-zone calculators. Modern software platforms offer robust capabilities that manual templates cannot match: IEC Risk Assessment Calculator - Download
Rare (1 hour/year to 1 day/year) or Frequent (1 day/year to 1 week/year).
While the IEC standards provide the formulaic backbone, manual calculations can be time-consuming and prone to human error, particularly when assessing large or diverse structures. SIRAC acts as a companion tool, allowing users to input specific parameters of a structure—such as its location, dimensions, construction material, and electrical systems—to receive a rapid, compliant risk assessment 1.2.1. The Role of SIRAC in IEC 62305-2 Compliance Henderson was hovering over his shoulder now
: Loss of service to the public (e.g., power outages, telecom failure).
The International Electrotechnical Commission (IEC) is a global organization that develops and publishes international standards for electrical, electronic, and related technologies. One of the key standards for ensuring the safety of electrical installations is the IEC 62305 series, which provides guidelines for lightning protection. A crucial component of this standard is the risk assessment process, which helps determine the level of risk associated with a particular electrical installation. To simplify this process, the Simplified IEC Risk Assessment Calculator, commonly referred to as SIRAC, has been developed.
: Commercial lightning protection manufacturers often provide their own calculators updated to the latest IEC 62305-2/3 standards. Manual Calculation Tables While the IEC standards provide the formulaic backbone,
A certified SIRAC tool ensures that the calculations strictly mirror the latest revisions of the IEC 62305-2 standard. Choosing the Right Class of LPS
Creating a feature for the involves digitizing the parameters found in IEC 62305-2 Annex J . This tool was originally designed to assess lightning risks for simple, single-zone structures without requiring the exhaustive calculations of the full standard. ⚡ Core Functionalities of SIRAC
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).
): Loss of service to the public (e.g., power outages, telecom failure). Risk 3 ( R3cap R sub 3
Review the generated zone classification and risk score. If the risk is unacceptable, users can simulate "what-if" scenarios—such as increasing ventilation or lowering process pressure—to see immediate risk-reduction feedback. Benefits of Using SIRAC
