Lightning Risk Preliminary Assessment

What does it assess?

This tool produces an indicative preliminary assessment of how urgently lightning-related risk at your facility should be addressed. Your answers are scored under three headings: lightning exposure, operational consequence and the gap in existing protection. Together they give a low, medium or high priority level.

Which inputs are used?

• Facility profile: facility type and the province in Türkiye. The province is matched with WWLLN Global Lightning Climatology 2010–2020 (0.5° grid) long-term lightning stroke density.
• Exposure: structure height (under 10 m, 10–30 m, over 30 m) and the surrounding setting (dense, partly exposed, exposed or dominant).
• Operational consequence: people density and how critical the operation is.
• Protection status: lightning protection system, surge protection (SPD) and periodic earthing checks.

What does the result mean?

The report gives the overall priority level, a separate level for each of the three headings and the factors that raised them. A high priority means the site data and existing protection should be reviewed by an engineer first. "Unknown" answers also add to the protection-gap score, because protection whose condition has not been confirmed is treated as a gap.

Limits

• The result does not replace a formal IEC 62305-2 engineering risk assessment.
• The lightning density used is climatology context, not a validated NG/NSG value for IEC 62305-2.
• The tool covers provinces in Türkiye only.
• The result is not shown on this page; it is sent only to your verified email address.
