Which classification of fire cause is considered accidental?

Accidental fire cause classifications involve incidents that occur without intent to start the fire. Unintentional actions suitably describe this category as they stem from mistakes or failures rather than any conscious decision to ignite a fire. Examples of unintentional actions could include things like leaving cooking unattended, electrical malfunctions, or other everyday mishaps that inadvertently lead to a fire.

Understanding why unintentional actions are classified as accidental is crucial for fire investigators, as it aids in identifying causes and preventing future incidents. Other types of fire causes, such as intentional acts, are the result of deliberate decisions to start a fire, while naturally occurring events refer to fires ignited by natural phenomena such as lightning strikes. Chemical reactions might also lead to fire but do not inherently imply intent or accidental nature.
