What I remember from decades back is that ARFF's primary mission is to provide a safe path for evacuation.
Minimising damage to the airframe and preventing fire spread comes after.
There have been many invocations in this thread of the hazards to the slides and evacuating pax from burning pooled fuel. But I can not recall any cases where evacuating pax suffered injuries from this particular hazard.
There is also the argument that in a timely evacuation, there will be less pooled fuel to worry about.
If anybody can let us know of any cases where pooled fuel imperiled an evacuation, it would be a useful contribution to the discussion.
There are of course a number of cases where pax succumbed because they did not evacuate in time.
