Select the chemical or dust profile from a pre-loaded database or enter custom safety data sheet (SDS) variables.
The physical attributes of the building—length, width, and height—are critical. SIRAC uses these dimensions to calculate the , which represents the statistical zone around the building most likely to intercept a strike. 2. Environmental Factors Ground Flash Density ( Ngcap N sub g
By translating the equations and decision trees of these standards into a logical calculator format, SIRAC helps facility managers quickly identify the "Zone" classification (Zone 0, 1, 2 for gases; Zone 20, 21, 22 for dusts) and determine if existing risk reduction measures are sufficient.

SIRAC Tip: When in doubt, lean toward S2. Under-estimating severity is the most common cause of non-compliance.

The number glowed red. The risk was fifty-two times higher than the legal limit allowed by the IEC standard.
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. Under-estimating severity is the most common cause of
In industrial environments, safety is not an afterthought—it is a regulatory and operational necessity. When dealing with explosive atmospheres, the International Electrotechnical Commission (IEC) sets global benchmarks, particularly through the IEC 60079 series. However, navigating these dense standards to determine explosive risks can be daunting.
The Simplified IEC Risk Assessment Calculator (SIRAC) is a valuable tool for organizations performing IEC risk assessments. By streamlining the risk assessment process, SIRAC helps organizations identify and mitigate potential hazards, ensuring compliance with the IEC 61508 standard. With its user-friendly interface, configurable features, and customizable reporting, SIRAC is an effective solution for organizations seeking to simplify their IEC risk assessment process.
