SPG exploding when tank turned on?

meekal · Dec 23, 2006

We've all been told since day 1 you should ALWAYS turn your SPG away from you when you turn on (pressurize) your tank

why?

i guess it might go back to the day when Jacques first turned on his tank back in the day, but has ANYBODY -EVER- heard of this actually happening?

Yes on one occaision. Unbeknown to the chap in question, he had cracked his spg in transport. Boy did it go bang when the air was turned on.

When you have a console take a good look at the back.
In almost every case you'll find a small hole,...Take a peek:huh:
There you'll see the metal back of your SPG AND a small plastic plugg.
In the unlikely case of a blow out the plastic plugg will be shot out like a bullet

The case or the glass front will not EXPLODE:no
So when you open your valve look at the frontside not the rear.

did it actually explode with glass and metal schrapnal and the whole kit-N-kaboodle or just make a terrible noise like tank burst disc bursting?

I saw one SPG blow, well actually I heard it blow, and that was at depth. The SPG blew off the guys HP hose. Did the gauge break? Who knows, we never looked for the gauge. He made a normal ascent with his buddy and had enough air to make the normal ascent.

I don't like taking chance I hold it away and try to keep the front and back pointing away from everyone.
