What is another term for the fully developed stage of a fire?

The fully developed stage of a fire is often referred to as the "inferno stage." At this point in a fire's lifecycle, it has reached its maximum heat and intensity, with combustion occurring throughout the available fuel and air. This term effectively conveys the chaos and destruction commonly associated with a fire once it has spread significantly and is actively consuming all materials in its path.

While terms like "flame stage," "combustion stage," and "active burning stage" reference important phases or aspects of fire behavior, they don't capture the full breadth of what is meant by the fully developed stage. "Flame stage" implies visible flames but may not denote the full intensity of the fire. "Combustion stage" addresses the chemical process of burning but doesn't specifically define the scale or development of the fire. "Active burning stage" might suggest that the fire is in a vigorous burning state without indicating that it has reached its peak potential for damage and spread. The term "inferno stage" clearly indicates that the fire has escalated to a critical level, making it the most appropriate term for this stage.
