Using the involves a systematic workflow. Here is how a professional would deploy it on a packaging machine or robotic cell.
IEC 62305 & 62561 Standards for Lightning Protection Explained!
SIRAC calculates the required safety level. You still need to validate that your actual safety circuit (wiring, relays, logic) achieves that level. A SIRAC output of PL d means nothing if you installed a PL c relay.
The tool guides users through evaluating a hazard based on several key parameters. The final SILrcap S cap I cap L sub r simplified iec risk assessment calculator sirac
SIRAC was designed to be straightforward. A screenshot of its interface shows a clean layout typical of early 2000s utility software. Its key features and intended use cases included:
The SIRAC tool is suitable for a wide range of organizations and industries that require IEC risk assessments, including:
The is an invaluable tool for designers, engineers, and safety officers ensuring that structures are adequately protected against lightning strikes. By automating the complex mathematical requirements of the IEC 62305 standard, it provides a fast, reliable, and compliant way to assess risk and protect human life and property. Using the involves a systematic workflow
Installed a safety-rated interlock switch (PL e) with a guard locking device that prevents the machine from restarting until the door is closed and locked.
The Simplified IEC Risk Assessment Calculator (SIRAC) played a crucial role in the history of electrical safety standards. As an official tool provided by the IEC, it succeeded in its mission to make complex risk calculations more accessible, speeding up the adoption of IEC 62305-2 worldwide. While it has been removed from current editions and is no longer considered a compliant tool for new projects, its legacy as a pioneer in user-friendly safety software is secure.
The primary goal of SIRAC was to democratize the complex calculations required by the standard. By automating the mathematical heavy lifting, the tool allowed engineers to focus on analyzing results and selecting appropriate protection measures, rather than getting bogged down in the manual application of formulas. It was, in essence, the standardized companion that helped bring a complex international document to life. SIRAC calculates the required safety level
The core principle of SiRAC is the simple risk equation: . A "control band" approach groups workplace risks based on a combination of hazard information and exposure information, leading to recommended control strategies. The process can be broken down into a series of steps:
Based on the input, SIRAC calculates the likelihood of direct strikes to the structure, strikes near the structure, and strikes to incoming service lines. 4. Mitigation and Reporting
