Elias typed in the dimensions. Length: 25m. Width: 15m. Height: 10m. SIRAC instantly calculated the collection area—a virtual net that determined how likely lightning was to strike the building. It was a geometric probability, cold and hard.
Installing air terminals (lightning rods), down-conductors, and earth-termination networks.
SiRAC was developed by the IEC Technical Committee 81, Working Group 9, which was responsible for the risk management aspects of the new IEC 62305 series on lightning protection. The need for such a tool arose because Part 2 of this standard introduced a structured but mathematically rigorous method for managing risk.
Industrial facilities, commercial properties, and infrastructure projects face constant threats from atmospheric discharges. Designing an effective Lightning Protection System (Socio-Economic / LPS) requires a meticulous evaluation of risk. For engineers, safety professionals, and facility managers, the International Electrotechnical Commission (IEC) standard is the global benchmark for lightning risk management. simplified iec risk assessment calculator sirac
, the user can simulate adding protective measures—such as installing a Class I to IV LPS or adding specific Surge Protection Devices (SPDs)—to see how much the risk value drops.
Enables small-to-medium enterprises (SMEs) to complete a defensible risk assessment without deep expertise in mathematical risk modeling, while remaining compliant with international harmonized standards.

Several Malaysian universities, such as UTHM, have conducted competency courses to certify staff in the SiRAC methodology.
Lightning does not need to hit a building directly to cause damage. Strikes to connected lines can induce massive surges.
Ensures that every risk assessment follows the exact methodology prescribed by IEC 62061 , promoting consistency across different projects [2]. Height: 10m
Allows them to integrate safety into the early stages of facility layout design, placing potential ignition sources far away from calculated release zones.
Select the chemical or dust profile from a pre-loaded database or enter custom safety data sheet (SDS) variables.
The Simplified IEC Risk Assessment Calculator (SIRAC) is a structured tool or software methodology used to evaluate the likelihood and consequences of hazardous events in environments containing flammable gases, vapors, or dusts.
