Cue 4-width of base of harm is about the width with the gasoline product rather than larger than two situations the width from the gasoline product.
Their review reported that the fire damage to the floor and inside cross portion from the wallboard happens progressively in the next way:
Two methods are used to visibly interpret damage on gypsum wallboard (one) cross-sections in the wall can be evaluated for visibly identifiable variations on the gypsum wallboard by depth and (2) the area outcomes may be evaluated for visibly identifiable different DOFD.
