Couple of points of interest:
The RTO test was undertaken at Istres. This is a military airfield (hence no civil ARFF, and not a lot of heavy jets) with a loooong runway (designated as a Space Shuttle alternate - but also means RTO's there usually mean move the throttle lever to idle and wait for the bird to stop). Basically I would suspect the firemen had no prior training specific for this A340 test should it go wrong.
