As part of our series on fire investigations, we will be discussing the cause categories of a fire.  There are four defined groups for the cause of a fire.  These are; accidental, incendiary, natural and undetermined.  This week we will discuss accidental causes.


Accidental fires are those where the proven cause does not involve an intentional human act to ignite or spread fire into an area where the fire should not be.  “Classification of Fire Cause” NFPA921Guide for Fire and Explosion Investigations. 8th ed. Quincy, MA: National Fire Protection Association, 2014.  Print 20.1.1

Some of the most commonly reported accidental causes include cooking, heating equipment, smoking and electrical equipment.
