Having said that, Kirk cautioned that investigators should not place “over informal emphasis” on inserting a immediate relation among char depth and time of burning as a result of the volume of variables which could affect the conclusions and The dearth of reliably managed exam details out there (Kirk 1969).

It wasn't until finally 2008 that NFPA 921 changed the definition from the expression with the introduction with the term fire outcomes. The definition of fire styles developed to “the seen or measurable physical adjustments, or identifiable shapes, fashioned by a fire outcome or team of fire results” (NFPA 2008).
