Imagine a small medical clinic ("Wellness Center") being built in a region with high thunderstorm activity. Data Input: The engineer enters the clinic's dimensions ( ) and notes it is surrounded by trees of similar height. Environmental Factors: They input the ground flash density (e.g., 3.7 flashes per km squared per year). Risk Analysis: The calculator evaluates Loss of Human Life (Type 1) based on a "Low Panic Level". The Result: SIRAC compares the calculated risk ( ) against the tolerable risk ( cap R sub cap T , the tool alerts the engineer that a Class III LPS or surge protection is required. Modern Alternatives It enables engineers and safety professionals to determine
Tools like , SICK Safety Designer , or Siemens SISTEMA often include a SIRAC-style module.
Selecting between Class I to IV Lightning Protection Systems.
