I don't believe a word of it.
I been fillin dot cyls for 50 yrs, and I ain't found a place yet in CA or OR, or AZ that even has a scale. Its all done in gallons, or should I say the OPD, or the bleeder valve or both. So what, every filler in 3 states is wrong or illegal, or dangerous ?? Get real.

To answer your question. Just because something is NOT illegal does not mean it is SAFE. IT IS DANGEROUS. If you have been "fillin" DOT cylinders for 50 years, you should have rudimentary knowledge of LP. Since you obviously do NOT, I will enlighten you. I have been licensed by the state of Texas for 36 years in Dispensing AND Repair. In Texas, you MUST be licensed to Fill and Repair LP systems and appliances. OPD devices do NOT always stop the fill at the SAFE 80% level. Also, IDIOT fillers will also keep filling when the OPD fails to shut off at the correct level but stop a few seconds after a safe level. IF you have the 80% valve open and are dumb enough to fill by OPD, you STOP when liquid spews out the 80% valve. NOT WAIT FOR THE OPD TO SHUT OFF. WEIGHT filling means that you always get the CORRECT liquid level in the Tank. The OPD is there in case your scale is off or you did not set the scale correctly. BUT you ALWAYS open the 80% valve and STOP when it spews liquid. The danger of overfilling is this. You fill at 60 degrees ambient and the idiot overfills your DOT because he did not use weight as the fill method. You then take your Tank to a hot 95 degree area. Guess what happens once that tank starts to react to the 30 degree rise in temps? It then spews LP because there is no room for the LP to expand in the tank. It is NOT illegal in most areas to Text and drive. But it IS dangerous for them and YOU. Doug
