The difficulty of evacuating occupants (e.g., hospitals, high-rise buildings, or schools). 4. Connected Service Lines

The International Electrotechnical Commission (IEC) is a global organization that develops and publishes international standards for electrical, electronic, and related technologies. One of the key standards for ensuring the safety of electrical installations is the IEC 62305 series, which provides guidelines for lightning protection. A crucial component of this standard is the risk assessment process, which helps determine the level of risk associated with a particular electrical installation. To simplify this process, the Simplified IEC Risk Assessment Calculator, commonly referred to as SIRAC, has been developed.

Automating complex formulas removes the risk of decimal placement errors or misapplied coefficients. Release is not expected to occur in normal

What happens inside the building determines the severity of a potential strike. Type of internal wiring and shielding.

SIRAC operationalizes the from IEC 62061 (Annex A). It calculates Risk Reduction and determines required SIL (Safety Integrity Level) or PL (Performance Level) by scoring four parameters:

Helps them monitor plant compliance and update risk registers dynamically when plant configurations change. The engine uses these parameters to construct a

| Hazard | S | F | P | Pr | Risk Class | Required SIL | |--------|---|---|---|----|------------|----------------| | Rotating shaft access | 2 | 2 | 2 | Medium | 4 | SIL 2 | | Chemical spray | 1 | 1 | 1 | Low | 1 | No safety function needed | | Unexpected startup | 2 | 2 | 2 | High | 5 | SIL 3 |

Lightning does not need to hit a building directly to cause damage. Strikes to connected lines can induce massive surges.

Release is present constantly or for long periods.

A robust SIRAC feature should focus on automating the comparison between and Tolerable Risk ( RTcap R sub cap T ) . 1. Structure Parameter Input

SIRAC allowed users to enter basic data like building dimensions, location (urban vs. rural), and occupancy type. Instead of manual calculus, the software used drop-down menus to apply pre-set risk reduction factors. For a small office or a simple warehouse, an assessment report that used to take hours could be generated in minutes. 2. The Practical Reality
