The dry powder is a chain breaking extinguisher it has no post fire security ie no cooling properties, the fire is still producing vapours which is the cause of the re-ignition, basic chemistry of fire as you heat a substance if it is a flammable substance as it warms it starts to produce flammable vapours which support combustion. simple peeps.

@macthefireman hehe cool I still have a couple of halon extinguishers hang. but they work very well.

Halon is no longer used because it breaks down the Ozone layer, not because it is bad for your health. Ironically, if it is used on a fire then it causes no problem to the ozone layer, but the vast majority of the Halon that is made will eventually just be released into the atmosphere, thus the ban on it's use.

The metal container is not cooled by the dry powder, should be followed up with foam fire extinguisher.

The flammable liquid used in the demo reignites because it has reached its auto ignition temperature.

But they stopped using Halon 1301 because it is bad for your health.
