Structural Safety Tag
https://schema.aidops.org/vocab/structural-safety-tag
Safe-to-occupy tag assigned to a structure by a qualified engineer or trained shelter assessor during a rapid post-disaster assessment, using the green/yellow/red taxonomy codified by ATC-20 and adopted by many national building-safety authorities. This is optional in a humanitarian administration: a household enumerator is not expected to assign a structural safety tag.
Standard reference
ATC-20 Post-Earthquake Safety Evaluation of Buildings (https://www.atcouncil.org/pdfs/ATC-20overview.pdf)
The three-tag taxonomy is standard in rapid structural assessment across earthquake-prone jurisdictions and has been adopted for post-cyclone and post-flood assessments.
