*Please skip to the end (2nd to last paragraph) if you just want to see my question.
Just today I had went to my local scuba shop to have my 98cf carbon fiber fill tank refilled, just as I have a few other times. Yet today I was met with a valley boy surfer dude to perform the fill. As I waited my turn to arrange the fill, he had an uncanny memory and knew everyone that came in the shop by their first name, "DUDE". My turn came up and told him I was the one who called to get my airgun tank filled to 4500 psi and asked if he's able to do this now or if there were others ahead of me. "Oh Dude I can get it filled up in a couple minutes". Really (eyebrows raised), I guess I'll wait then. Knowing the last time I had this done here, it took about an hour. So I was rather surprised how quick this could be done.
He took the tank to their fill area in the back of the shop, which was still within my view. I could see him sort of scratching his head tinkering around with my tank and even removed the pressure relief valve knob as if to try and connect an adapter there to fill it. I saw this and politely asked, oh I didn't know you fill the tank through the relief valve. "Oh yeah dude" as he laughed screwing it back on. He then fumbled around grabbing and looking at different adapters with a confused demeanor, and also reached for different hanging hoses and dials as if he was trying to figure which one to use. He then gets on the phone to call someone to ask them how he should go about filling the tank. After the call, by my new first name, he apologized, telling me it's probably going to take about 30 to 40 minutes to fill it to 4500 psi and that I can come back later to pick it up. So I reluctantly opted to leave him with the tank and ran some errands. I called after 40 minutes and was told he was having some problems getting it to 3000 psi and was going to try something else or a different adapter and to give him another 30 to 40 minutes.
To to keep this already long post, less longer, I returned to pick up my tank, to find out that he was only able to get about 3k psi in it. He apologized and said there would be no charge and I could bring it back tomorrow or another day to have someone else fill it up. As I drove home, I mentally revisited the whole event in my mind as a truck full of oxygen tank pulled up next to me, while we waited for the light to change. For some reason, I could not get it out of my head wondering if this guy could have accidently put oxygen in my tank. And for obvious reasons had this impending doom I couldn't shake if this was the case. No amount of googling helped me resolve this mystery.
So I'm hoping someone here in AGN that's in the know can inform me if it is remotely possible for a "dude" with a head full of air and a Bill & Ted accent, to accidently fill my air tank with oxygen? For the life of me I could not find the answer anywhere on the web. And now I'm terribly afraid to use this tank, or connect it to my booster pump to fill up my pcp's until I can confirm whether filling it with oxygen is easily possible, or not.
Any help on this topic will allow this dude to get some sleep and be at peace shooting the air out of my pcp's. Thanks...
