A scale starting from 0 to six was created for assigning a DOFD, with 0 indicating no noticeable hurt and 6 indicating comprehensive use. Thirty-9 “beginner” raters done an analysis of damage to some wall surface, finishing sixty six ratings initially without the DOFD strategy and next, repeated score with the new DOFD strategy. The effects indicated that the amateur raters ended up far more trustworthy in their analysis with the DOFD to gypsum wallboard when utilizing the DOFD technique. These results aid the usage of standardized processes to decrease the variability in information assortment and interpretation.
Hicks et al. (2008)) mentioned that the strains of demarcation through the entire compartment would descend in elevation dependent on the header depth and sort of opening, apart from the line of demarcation would descend reduced in corners and ascend in the vicinity of ventilation openings.

This was also observed on partitions opposite door openings” (Shanley et al. 1997).
