To keep the tool user-friendly, SIRAC makes several technical trade-offs:
(economic loss), the tool calculates a cost-benefit analysis to determine if investing in an LPS is financially justifiable. Key Input Parameters Required by SIRAC simplified iec risk assessment calculator sirac
To provide an accurate assessment, the tool requires specific data about the structure and its environment: Structure Dimensions To keep the tool user-friendly, SIRAC makes several

If the calculated risk ( ) is greater than the tolerable risk ( RTcap R sub cap T ), a lightning protection system must be installed. For R4cap R sub 4 If the calculated risk ( ) is greater
The calculator combines these four inputs. Generally, if you have S2 + F2 + Pr2 + Av2 , the calculator will demand the highest safety level (SIL 3 / PL e). If you have S1 + F1 + Pr1 + Av1 , it may demand no safety requirement or a very low level (SIL 1 / PL a).
