While no exact temperature is associated with flashover, a range of approximately degrees Fahrenheit is widely accepted.

Flashover is a critical event in the progression of a fire where the combustion of all combustible materials in a room occurs almost simultaneously. This phenomenon is influenced by various factors including the temperature of a fire, the materials present, and the geometry of the space. The accepted temperature range for flashover is typically around 1100 to 1200 degrees Fahrenheit.

When a fire reaches these temperatures, the heat released can ignite unburned materials, leading to a rapid increase in fire intensity and spreading throughout the area. Understanding this temperature range is vital for firefighters, as it helps them recognize the signs of an impending flashover and take appropriate safety measures to protect themselves and the occupants of the building.

The selection of the highest temperature range of 1500-1900 degrees Fahrenheit does not align with the widely accepted understanding of flashover temperatures. While fires can reach very high temperatures, the critical flashover event typically occurs at lower temperatures in the ranges accepted by fire behavior studies. Knowing this helps firefighters effectively strategize their approach to mitigating fire hazards.
