Question

In two sentences:

What is the essential element needed for fires to progress into the fully developed or flashover phase?

Answer 1

There must be sufficient fuel and oxygen for the fire to reach flashover. If the initial object that is ignited does not contain sufficient energy (heat of combustion) and does not release it quickly enough (heat release rate), flashover will not occur (e.g., small trash can burning in the middle of a large room).

Step-by-step explanation:

100% CORRECT

Answer 2

Fires require the same things as us. Energy and oxygen. Energy is wood or a flammable substance and oxygen.
