Self serve LPG? Update; link added

[beemerphile1]

Read an article that the new Menards being built in my town will have a self serve LPG filling island in the parking lot. The article described it as if you will connect and fill your own cylinders.

Ever see one? I haven't.

UPDATE:
Well, I did find a link. It specifically says "Self-serve Propane Filling Station"

Well.. misuse of 2 words in procedure manual can be matter of life or death when dealing with propane.

And YET they are going to let 'John Q. Public' fill their OWN propane at Menards new store :S

1. I am CERTIFIED in LP filling and LP repair on RV's. I have been for 38 years
2. Your comments just show that just because YOU have had POOR and dangerous filling practices does NOT make YOU an expert on LP systems.
3. The ONLY time you will vent liquid or vapor is when you disconnect and that amount is negligible. It disperses rapidly in the air and does not reach the proper LP/Air mix to cause an ignition source
4. The venting of Vapor while filling from the 80 percent valve is WHY, you do NOT have an LP filling station close to any other ignition sources(ASME Motorhome tank), and why you turn the tank valve OFF and have the appliances OFF.
5. People like you will beat a dead horse because you really have no knowledge of what you are talking about. You just THINK you know everything. Doug

So we have another CERTIFIED who doesn't open bleeding valve when filling up cylinders?

Reread item #4.....80 valve---'bleeder valve'
Liquid Level Valve etc.
Venting of Vapor until liquid spews then cylinder/tank is FULL

Okay, which is it? Number 4: "venting of vapor...from the 80 percent valve" or number 2: "The ONLY time you will vent liquid or vapor is when you disconnect and that amount is negligible."?

I made a small error. You ALWAYS open the 80 percent valve while filling. Number 3 was in response to HOW you disconnect the fill nozzle and there would be negliable liquid or vapor when properly disconnecting from the Tank. Not enough to cause a hazard if done properly. Doug

@Doug, those are European pumps. The only place I've noticed one in NA is the gas station next to Wal-Mart in Whitehorse YT.

They sell propane refill plumbing kits now in the stores for refilling special refillable 16 oz. bottles (these are blue color, instead of green). Cool the little blue bottles in the freezer for awhile, then fill them from a regular 5 gal. BBQ tank that is held upside down using the refill plumbing kit. The little 16 oz. blue bottles cost around $10 and can be refilled over and over.

Our RV'ing friends do it all the time for when they tent camp. (However, I want no part of it ... just to save a few bucks.)

These kits and their use is legal in California - believe it or not!

The crappy valves on the green bottles were always the issue, rather than the process itself.

Funny story about LPG,,
A friend of mine went visiting his grampa on his farm and noticed hes got one propane botle hanging upside down and another bottle down below it,
,both conected together..asked what the heck is he doing,,
was told hes trying to drain propane from the above tank to the lower one...

Been doing it for years having forklift tanks transferred to 2 gallons tank that would no longer be accepted by fill station.
Left alone - the overnight temp change would push some propane between the tanks.
At the end you just open the bleeder to confirm the level .

Image a big bertha where the explosion did not flash. The FAE is a special purpose weapon that is utterly unlike a TNT bomb.

It lights up and stays lit for 5 seconds. How many big bertha's does that equal? A lot.

The overpressure wave is incredible.

Watched a demonstration of an FAE at a cave entrance in Tora Bora. FAE detonated at a cave entrance and krap flew out of four or five openings on the other side of the hill -- up to a half mile distant through a tunnel network. Stuff like sandbags and various parts with clothing and rocket propelled grenades and lots of rocks and dust.



In southeast Asia, the reaming of a tunnel network by the Marines and Special Forces was quite a specialty. We boys in dungarees and boon dockers only got glimpses of that nasty job.

Back on track...the "thermo" part is minor. It's the effect of the pressure that keeps coming and coming, like a Tsunami, that does all the damage.

The problem with all this is that when an LPG leak in a confined space gets to an air fuel ratio that can support combustion, it isn't dynamite. It's worse. It's a fuel air explosion.

A GC220 that detonates sounds similar to a 12-gauge shotgun discharging.

When overpressure is developed and a half mile away stuff in a tunnel goes ptui at high velocity out the other side it is pressure not thermal that processed the tunnel contents.

When I was Repair Boss on a Submarine Tender, my Divers had a Hyperbaric Chamber for treating divers that had Decompression Sickness or the Bends.

Never heard of a Hyperbaric Bomb, but a Depth Charge does its damage by Hyperbaric pressure waves - over-pressure waves.

Similar damaging effects by Bunker Buster Bomb and Big Bertha bomb - massive over-pressure.

Hyperbaric therapy is supposed to describe constant pressure on the affected area.

Assisted breathing forces it's way to the lungs. If it affected your lung expansion it would pop your pajama buttons. You could sleep in a two atmosphere environment. The effects would be better sound transmission -- higher db snoring, with no improvement in apnea. Only by raising O2 significantly can apnea be treated without positive airway unblockage.

Too much physics schooling can be blamed for my choice of hyperbaric over thermobaric.

When overpressure is developed and a half mile away stuff in a tunnel goes ptui at high velocity out the other side it is pressure not thermal that processed the tunnel contents.

"Vehicle Has Damaging Flat Tire" seems to be a wanting description to describe a rollover.
