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. ...

"What could possibly go wrong?"
Were were trained by MSA (Mine Safety Appliance) for LPG Dispensing. Before the days of the OPD overfill protection device.
I have no idea how this is done in the USA these days.
Back then, overfilling a tank was called "stuffing the tank". Mention "stuffing the tank" to a propane distributor and his hair would stand up on end.
Liquid propane squirted on a hand would give INSTANT frostbite. Damage. Doctor. Hospital. Needless to say about what liquid propane in the eyes would do.
Anyone who RELIES on floats and non return valves instead of brains, needs a lobotomy. Four gallons of exploding LPG at Stoichiometric Optimum, ideal air fuel ratio -- would utterly destroy a four bedroom house. Nothing left but a concrete slab that looked like it has been swept.
I urge everyone to take a bit of time to learn how to do this correctly. Most propane distributors would be tickled pink to spend ten minutes giving pointers. Take a box of donuts.
It just isn't worth injury, disfigurement or death...

- Check for receiving vessel cerification validity
- Visually check for corrosion, bent guards, damaged valve handles, tank dents
- Verify operation of the fill bleed valve. Crack the fill bleed valve open
- Grab the dispenser hose. Close the bleed down valve on the dispenser nozzle. Attach and tighten the POL or Fast Fill dispenser nozzle
- Open the receiver tank valve all the way until tight
- Open the dispenser **** valve
- Start pump
- Verify tank bleeder valve is bleeding
- Fill until gas just starts to turn to vapor out of tank bleeder valve. Stop pump
- Close dispenser nozzle. Close receiver tank valve
- Shut tank bleeder valve
- Vent liquid LPG through the dispenser fill nozzle bleed down. The bleed down exit NEVER was close to the dispensing nozzle. Liquid vented ten to 12 feet away
- Detach dispensing nozzle from tank
- Verify fill integrity by opening tank bleed valve. Only gas must escape
- If visible vapor (liquid) was escaping THE TANK WAS PROHIBITED from departing. The bleed down was left open and monitored until such time as only gas was venting.
