Web2. Pool fires . 2.1 Pool Fire Dynamics The structure of most pool fires may be split into a number of fairly well-defined zones: • The liquid fuel itself. In deep pools there may be significant convective flow within the fuel which may affect the fuel vaporisation rate and hence influence the ‘external’ characteristics of the fire.
