The fire pattern scientific studies unveiled which the upper layer damage is very difficult to discover once the fire has transitioned into air flow-controlled problems. The presence of the soffit and the scale of a gap influences the depth with the harm within the compartment, nonetheless, given that the compartment nears flashover destruction begins to come about at decrease elevations on all surfaces.
The scientists utilised ImageJ computer software plus a Kodak gray scale and found superior arrangement between the optical measurement approaches and smoke pattern pictures developed alongside wall surfaces. Their research confirmed that “the smoke pattern was determined to the wall checks and showed a difference between examination conditions and very good arrangement for the tactic for all examination situations” (Riahi 2012). In addition they mentioned that “based on the clean up zone spot, the flame top as well as fire size can be calculated” (Riahi 2012). Last but not least, the study was executed with a range of digital cameras they usually found that the optical Homes weren't depending on the camera made use of.
