A flashover is the near-simultaneous ignition of most of the directly exposed combustible material in an enclosed area. When certain organic materials are heated, they undergo thermal …

Oct 30, 2024 · When everything ignites almost at once, it’s called a flashover—the transition from a growing fire to a fully developed one. It’s not a surprise event; it’s a predictable shift driven by ...

May 1, 2025 · What is Flashover? A flashover is defined as a transitional phase where all exposed surfaces in a compartment reach ignition temperature almost simultaneously, leading …

The purpose of this whitepaper is to explain the science behind the phenomenon of flashover and outline the important role that live fire training plays in teaching firefighters to recognize the …

Jun 10, 2025 · A flashover occurs when everything in a room ignites. It's like cooking popcorn: a few kernels gradually pop, but almost all of them burst open at the same time.

Jun 22, 2010 · A flashover occurs when all of the combustible materials in a room or compartment reach their ignition temperatures at the same time.

Flashover is the sudden transition to fully developed fire. This phenomenon involves a rapid transition to a state of total surface involvement of all combustible material within the …

Flashover typically occurs when the heat generated by a fire radiates back from the walls, floor, and ceiling of a compartment, sufficiently heating the room’s contents and gases to their …

Jun 12, 2023 · Flashover A transition phase in the development of a compartment fire in which surfaces exposed to thermal radiation reach ignition temperature more or less simultaneously …

A flashover is the near simultaneous ignition of all combustible material within an enclosed area. When many materials are heated, they release flammable gases.
