Burst disc for HP tanks

[DRE]

Tanks will only explode if they don't pass a hydrostatic test, ie a bad tank with shims will probably blow before the o-ring goes, but there is a very good chance that same tank will go with a burstdisk installed as well. Obviously you do want to maintain your equipment properly - I don't want to dive with shitty regs, nor do I want to dive with shitty tanks. Annual VIP's and current hydros go a long way to prevent tank damage.

In case of fire - don't you think a rubber o-ring will melt long before your tank will explode?!


In Europe tanks do not have burstdisks and they don't have problems - at the same time (and this is different from country to country) they do require hydrostatic testing more often (annually or bi-annually). And BTW, steel tanks don't explode like a handgrenate, they split - aluminiums will shatter, but then again you should never overfill al's in the first place so it's a moot point anyways...
