The municipal structure for providing rescue services has received an alarm
concerning a tank lorry that is on fire. The fire brigade personnel on site
sense that the radiated heat is extreme, to the extent, they understand, that
it has caused another vehicle some distance apart to catch fire. After the
event everybody remembered the intensity of the heat, not least since it had
caused a second vehicle, out of range of the fire, to burst into flames. On the
next occasion of a tank lorry fire, they were aware, through the
experience gained, of the need to take measures to prevent the fire spreading
through heat radiation. One can read about such a situation and calculate
what a safe distance would be. But it is when the situation is met in reality
that it makes its mark and the experience is gained.
