What are the four classifications of fire?

The four classifications of fire encompass a broad spectrum of causes and motivations behind fire incidents. Accidental fires arise without intent, often resulting from negligence, equipment failure, or unforeseen events like lightning strikes. Natural fires can occur due to environmental conditions, such as wildfires ignited by natural phenomena. Incendiary fires are those that have been intentionally set, typically with malicious intent.

By recognizing that these categories cover the range of potential fire origins—whether through accidents, natural occurrences, or intentional acts—it becomes clear that selecting all of the classifications collectively provides a comprehensive understanding of the various ways fires can be categorized. Each classification is critical for investigations and understanding fire behavior, making the inclusion of all three very pertinent to the overall study of fire incidents.
