Whilst oxidation is a process that happens everyday such as when metal rusts, the difference is the speed of which it occurs. Steve Swanson. Flashover occurs when the majority of the exposed surfaces in a space are heated to their autoignition temperature and emit flammable gases (see also flash point).

The level of risk that a material poses and how easily it can cause a fire is often affected by whether its flammable or combustible.
