Qualities from the destruction joined with air flow-created styles during air flow-managed circumstances are big area spots of injury, greater magnitude of harm, injury identified close to unsealed drywall seams and angled lines of demarcation located within the air flow opening or right opposite of a doorway opening.

It may be argued that this analyze was the closest any on the approaches have come to being tests for dependability or validity (Fig. 15 and Desk two).

The Mealy, et al. review (2013) also shown that when visual damage to the wall surfaces had been unable to offer more than enough data for Evaluation that contour plots on the depth measurements “furnished important Perception into the places in the enclosure which were subjected to the most severe thermal harm, the places through which the initiating (Key to start with gasoline) fire happened”.
