Dear Kenny,
Diesel being more like oil, it is not readily flammable.
There is no danger whatsoever to take a pic because the stuff won't light up as would gasoline would do.
I've sticked a propane torche in a diesel fuel filter, and guess what, almost no flames, and of course no explosion.
I'd really worry about driving a gas vehicule, 'cause gas is way more volatile than diesel.
KABOOOOOOOOOOOOOOOOOOOOOOM!
