What characterizes a smoldering fire?

A smoldering fire is characterized by a slow and low-burning process that produces heat and smoke but very little flame. This type of fire typically occurs when fuel is in contact with smoldering embers or heated surfaces, leading to combustion without the vigorous flames associated with a fully developed fire.

In smoldering fires, the combustion process is incomplete due to the limited airflow, which prevents the fire from reaching optimal conditions for flame production. This results in a fire that appears to be barely burning but can still generate considerable heat and toxic smoke. Recognizing the characteristics of a smoldering fire is crucial for fire investigators as it aids in understanding the fire dynamics and potential hazards present in the environment.
