The outcome indicated the novice raters have been a lot more responsible inside their Evaluation in the DOFD to gypsum wallboard when utilizing the DOFD technique. These effects support the usage of standardized procedures to lessen the variability in data selection and interpretation.
Combustion that fire investigators will most often face is predominantly diffusion flames. The combustion of the gas as a result of diffusion flames is inherently oxygen restricted because of the diffusion response and The supply of only 21 % of oxygen in air in very well-ventilated fires.
