Q:

Half new SCBA tanks

I recently bought 3 66 cf tanks from Dayotat and filled them this weekend.

My 3-44 cf tanks were already full, so I set up the cascade system to partially fill each 66 cf tank. Then I ran the Shoebox for 6 hours, changed the piggy back Harbor Freight dessitant filters and ran another 5 hours. The next day I ran it for another 6 hours and again changed the Harbor Frieght filters and ran it another 9 hours.

This morning I opened up the holes in my styrofoam tank holder I used for the 44’s, to fit the 3 66’s, then put the cascade system on it and filled the Pygmy tank and then topped off the 66’s with the Shoebox.

So with the air I have on hand, I can shoot my FX Royale 400, 4500 times before I need to run the Shoebox again. 😯

The water logged filters turn pink and get put in the oven at 170 degrees until they turn blue again, then I seal them in a seal-a-meal bag to keep them fresh.

I changed the 44 for the 66’s not entirely for more volume, but also for more current hydro-able tanks. The 44’s were 1995,1996, 1997 dated and the three 66’s that replaced them are all 2004 if I remember right, they were hydroed this month.

I get some shit for running expired tanks but I really have no trouble running them. The way I look at it, it is a matter of risk management. With RM you look at a population doing a certain activity, such as being over weight, or smoking or texting while driving. You take the total population, how many accident or incidents you have and determine what the risk is. All three of the things I mentioned above are extremely dangerous, if your fat, smoke and text while driving your tripple fucked, but if your fat, smoke and text wihile filling your expired tanks, historically they still are not going to blow up. 😆

However with the thousands of expired tanks out there and the fact there have been absolutely no accidents with the expired scba tanks, there is no way to figure a risk, for there simply is no defineable risk at this point.

I get in heated arguments on the Yellow about this, my latest answer to the sky is falling idiots, is show me the accidents, no one can show me the accidents involving air guners blowing up expired scba tanks for there have been none. One scba tank in service that was abused by a fireman by exposing it to corrosive chemicals in the back of his truck is the sole scba accident that can be cited. The owner of the stock making company in Indonesia blew himself up recently with a homade PCP pistol cylinder, but that is a different matter entirely.

So now I have to decide if I want to refill these 44’s or sell them cheap. One expires next month, it looks new, the other two are scratched up some but not frayed, I thought about shooting one at about 100 yards and filming it, but not being a camera buff, I am not sure I could pull that off.

Right now, historically and mathmatically, you stand a substantial greater risk to be struck by a astroid than having a expired SCBA tank used for airgunning blowing up. I am sure that statement will gall some of you, but like I say, show me the carnage. 😉

The thing is right now, I am fit, I don’t smoke or text at all, have recently hyroed tanks, so I should live forever. 😛

I fill with safety glasses and don’t look directly at the gauge 😀

RC,

if you decide to sell, let me know the ransom and ill see what i can do… 😉

😆 😆 😆 😆

Somehow I knew you guys would agree… 😆

These 4500psi tanks get heavier when you fill them right? 😕

Synopsys,

I always wondered why those deep wrinkles on your forehead ran up and down rather than sideways. 😛

It would be interesting to watch you put 4300 PSI in my Ranger 45.

You are not a pussy, you just understand the potential energy in one of these tanks. I’m nervous every time I fill a tank. 😉

Yup… 😆

Comfortable?

Not me!! 😀

Maybe it’s because i’ve only had my tank full for a couple of months… Plus I didn’t get the full 4500 fill, I went with a walk-in and out fill of 3600. Still I seatbelt that bitch into position and drive like a granny with it in the car.

Even though i’ve made a bunch of fills I always jump a little when the fitting locks into place.

I’m really happy my rifles only fill to 1600psi and are built for more as well as blowing a seal or check valve off well before they get to the danger zone.

Hell, with my AF tanks I didn’t even feel comfortable clamping then in a vise to get the valve out.

Yeah, i’m a pussy. 😆

The first time I got my used SCBA filled to 4500 the guy at the scuba shop was intent on having me purchase a “proper” steel or aluminum (whatever they are) scuba tank.

He regailed me with tales of “this one time” he heard of a woman talking out with a CF tank that failed as she walked out of the shop, human stains being cleaned from the ceiling shortly thereafter.

Bah, if you gotta go, you’re going, SCBA or not.

I googled the alleged incident, couldn’t find anything.

I have to admit I’ve gotten quite comfortable with these pressures over the past few months.

DUN DUN DUUUUNNNNNNN.

Jerry,

I have had a vision of my death and mostly know how it will happen .

At the age of 105 I will be boiled in a iron pot by the primitive tribal family of the 18 year old jungle princess I got in trouble. 😈

Sounds doable until you consider two things, first I will be 105 when it happens and second, what are the chances that even with vigra at 105 I will get a chubby over a gal with a bone in her nose ❓

But your shoebox is still smoking so you should still be very careful!
