Brett, what are you like?!?!?!
Glad you braved it and saved your gas, because as you proved, its not as scary as it sounds to deal with such an issue.
You should have been in my place one day when one of my not so smart EX-employees was carrying out some testing.
We had a nitrogen bottle which had a 3ft or so length of braided hose connected to it stood in the test room and I told him to connect it to a solenoid to test it. However, because the solenoid had a nylon pipe fitting for the ilet, he decided to get a piece of nylon pipe and a few adaptors to connect it to the solenoid rather than change the solenoid inlet to suit the braided. Now that would have been bad enough if he'd used our high pressure nylon pipe but he used the standard fuel type instead, which at the time was only rated at a few hundred psi.
When he turned the nitrogen on which had well over 1,500 psi in it, the nylon pipe burst and the force of the escaping gas propelled the braided hose like a demented snake lashing out in all directions RANDOMLY smashing everything within striking distance.
I grabbed a sweeping brush and attempted to pin the pipe down, so we could turn off the bottle valve and after God knows how many attaempts I finally managed it and all was back under control.
Needless to say I never entrusted him with anything more than boiling a kettle after that and we implemented some safety steps that we still use to this day, like having braided hoses that are attached to bottles, secured to the test bench in numerous places and having easily accessible QA valves somewhere close to the end.
Now this is another example of why nylon hose is so much better and safer than braided.
In a similar incident many years before when at a race track, the braided hose actually hit one of my guys thumbs and smashed it to bits BIG TIME. Whilst on yet another similar incident I was lashed by NYLON hose and only suffered relatively mild whipping before the hose broke off and ended the drama.
GIVE ME NYLON PIPE ANY DAY FOR EVERY JOB!!!! Chris,
As long as you take reasonable precautions, ensure the pipe is routed correctly and not subjected to any form of abuse, you'll be fine with your own large bottle, especially with our nylon hose.
