Phase 1 – Flashover Development Observation

Teach to recognize conditions that lead up to a deadly flashover event and learn techniques to delay this phenomenon – in a controlled, repeatable setting.


Two compartment design creates a safe learning environment

​The wood-fueled Phase 1 system is essentially a laboratory where firefighters can closely observe fire behavior and learn to recognize the warning signs of a flashover. The upper compartment is the burn chamber. The observation level, which is 3 feet below the fire floor, gives firefighters a safe vantage point for observing the stages of fire as it progresses to flashover.

This proven system is also designed to reinforce the proper use of personal protective equipment (PPE) and teach methods for testing and cooling the environment to delay the onset of a flashover.
