If your burning gasoline bundle was Positioned clear of the witness floor, the resulting fire pattern continues to be characterized as getting in The form of a “U”, evidenced by its radial or curved lines of demarcation (Hicks et al. 2008; NFPA 2014).
Nonetheless, not all fire investigators hold the similar volume of schooling and coaching, or appreciation with the conversation of your fire in its natural environment. Traditionally, fire investigators have been folks with none official training or education in scientific methodology. A study was carried out from the National Heart for Forensic Sciences (NCFS) in 2000 where 422 fire investigators exposed that only 33 % held a university diploma, of which only 10 % ended up linked to science or engineering (Minnich 2000).

The conical fire pattern theory progressed into a more systematized fashion because of the Kennedys (Kennedy and Kennedy 1985).
