What category do flaming ignition sources fall under?

Flaming ignition sources fall under the category of flaming sources, which are characterized by the visible flames that are produced when a combustible material ignites. This can occur from various types of materials or conditions that provide enough heat to ignite a fuel source in the presence of oxygen. Flaming sources are significant in fire investigations as they indicate active combustion, which can lead to rapid fire spread and poses higher risks than other ignition sources.

In contrast, smoldering sources refer to combustion that occurs without visible flames, primarily through the gradual oxidation of materials. Non-combustible sources refer to materials that do not ignite or support combustion, and electrically induced sources specifically relate to ignitions caused by electrical failures, short circuits, or sparks. Understanding these categories helps fire investigators accurately assess fire origins and causes, supporting effective fire prevention strategies and safety measures.
