CSI & diver in a tree

[The Kraken]

Kraken, the next thing you are going to tell me is that he was using an Air2!!

Why, of course he was, you dolt!!! That's what became defective and caused his tank to blow!!!

 

[crpntr133]

I don't know if I should be insulted or not...what is a dolt?...lol

I bet he wasn't wearing spring straps either or he would have had better control of his flight path and made a safe landing on the other side of the fire.

CSI= California Stroke Investigators.

Fire Diving is indeed dangerous!

I don't believe it, FL is ahead of CA, no way!

The scores after the first round:
Florida Fire Flyers (of Ft Myers) 17
Bay Area Bucket Divers 14
Gator Bait Bucket Divers 13
Jamaican Smokers 12
New Yawk Hawks 12
The Ft Myers Blaze Bouncers 9
Wing and a Flare 7

I have had the opportunity to witness more than one cylinder failure in a fire. And no, the burst disk doesn't always let go first. That's because the heat often causes the cylinder material to weaken long before the internal pressure is raised above the burst disk pressure.

Which is why we're supposed to store tanks either completely full or completely empty: its the "in between" pressures that can suffer a catastrophic blow due to metallurgical failure of the tank prior to the pressure rise having the burst disk cut loose.

And even if the burst disk goes, the current ones are an orifice design, which from a gas dynamics standpoint is a choked flow nozzle which limits a tank's "thrust" to push a diver up into a tree or whatever (assuming it was pointed in the proper direction and so forth).

FWIW, if you need the US regulatory citation for burst disks (aka "Pressure relief device systems"), its DOT 49 CFR 173.301 (a)(9).

Actually, if I'm not mistaken, the episode you are refering to with the diver in the tree, unless they did another one with a diver in a tree, he did not get there from having his tank explode. He got scooped up by one of the water bombers from the nearby lake and dumped there.
