Structural Collapse indicators require sound situational awareness of overall operational profiles, building conditions and operational task assignments. Wood Frame structures are impacted most significantly due to exposure and material degradation from direct flame impingement or failure mechanisims of crucial assembly connections or construction systems.

Frequent and Timely observations of structural conditions, impact of fire involvement and fire suppression operations conducted by response companies must be conducted. Establish appropriate collapse zones around the structural perimeter, utilize safety officers and practice effective risk assessment, situational awareness and incident monitoring to ensure operational safety. Collapse indications are sometimes VERY obvious....be aware of the operations, the building type and its inherent collapse charactoristics and your operational time.
