This is when your tank fails catastrophically and blows you into a 
million pieces because you dared dive without a pony.

Only kidding. The burst disk is a little disk of copper in your valves 
which is theoretically supposed to give way in the event of 
overpressuring your tank via overfill or heat.

In reality the disk flexes each time you fill your tank and eventually 
suffers a stress fracture causing all your air to depart in a rapid 
fashion.

Personally I double-disk (stack two) because a burst disk at the wrong 
time during a deco dive could ruin your whole day.

Europeans are lucky, due to the cool climate over there and complete lack 
of building fires, their valves don't need burst disks.
