What is defined as any unconfined open flame or device that can propagate fire?

The term that refers to any unconfined open flame or device that can propagate fire is live fire. This encompasses a wide range of situations where fire is not contained, whether it be from natural occurrences like wildfires or from man-made scenarios that utilize an open flame. Understanding this definition is crucial for anyone involved in fire training or firefighting, as it highlights the potential hazards associated with uncontrolled flames.

Live fire situations can lead to rapid spread and present significant dangers, making awareness and management of these fires a key component of fire safety measures.

Controlled burns, fire pits, and ignition sources refer to more specific contexts or equipment associated with fire management, but do not encompass the broader category that includes all forms of unconfined flames.
