This was The 1st time that a difference was drawn in between destruction due to the fire (fire effects) and clusters of fire outcomes that may have properties that aid the fire investigator (fire styles). Fire results are the Bodily or chemical changes that come about to various elements when exposed to the byproducts of combustion (e.g. melting of plastics, oxidation of metals). Fire designs are discovered as the collection of those effects and geometric designs that these consequences created.
