Oh granted, there is difference between a spark in vapour in the petrol
station and a cinder in liquid petrol. Recent report in the local rag
about a truck which rolled and spilled grain all over the carriageway
also mentioned leaking diesel and the consequent fire risk, and there
was me thiking you needed to compress diesel vapour before it will
burn...

Umm, you don't...

Diesel will burn quite happily given an appropriate source of ignition. Of
course the fact it isn't as volatile as petrol means it doesn't have the
vapour ready to go 'boom' in an exciting manner even if you're not actually
anywhere near any obvious liquid.
