This four-hour class deals with the issue of fire pattern production. Fire patterns, which are the visible or measurable physical changes to materials which are formed by a fire effect or a number of fire effects. The recognition and interpretation of these patterns forms the basis for fire scene investigation, and ultimately, origin and cause determination. This class will delve into a wide variety of issues relevant to burn patterns, including: types of fire patterns, temperature estimation, mass loss of materials, sooting, charring, spalling, oxidation, melting of materials, thermal deformation and expansion, calcination, clean burn, lines of demarcation, suppression effects, flash-over and its effects on burn patterns and pattern geometry.
