Wooie Posted January 25, 2013 Share Posted January 25, 2013 Make sure the 80% Cut Off Valve is working on your Re-fillable Gas System or this might happen :- http://www.aol.co.uk/video/shocking-video-car-explodes-at-gas-station/517653217/ Link to comment Share on other sites More sharing options...
thebishbus Posted January 25, 2013 Share Posted January 25, 2013 That cannot happen with Gaslow cylinders, they have a safety blow off valve. Brian B. Ps One of ours overfilled on the first fill in England. It started to release gas on the way down through Spain. I had to disconnect it and let the extra gas out.

Really?..So,what if this "safety blow off valve"..erm....well....didn't "blow off"? :-S Link to comment Share on other sites More sharing options...
Dave Newell Posted January 25, 2013 Share Posted January 25, 2013 For starters this was in Americas and some of their tanks have an odd arrangement where you open a bleed valve when you fill and watch for liquid propane to appear at this valve. Perhaps this chap forgot the bleed valve or just took his eye off it for a little too long. He obviously spots something has gone wrong as he tries to remove the filler pipe just before it goes bang, I'm amazed it didn't ignite though! D.

Derek Uzzell Posted January 25, 2013 Share Posted January 25, 2013 The accident was actually in Iran and CNG (Compressed Natural Gas) was involved, not LPG. There have been apocryphal tales of people putting CNG into vehicle gas- tanks designed for LPG and the tanks (unsurprisingly) exploding, but it's hard to see that actually happening as the connections will be quite different .

Iain Strachan Posted January 25, 2013 Share Posted January 25, 2013 Hi, in the instructions received with my Gas Lo installation there is a warning I quote" IMPORTANT: FIRST FILL ONLY.In some rare instance it is possible that on the FIRST FILL ONLY. the 80% shut-off may fail to activate. It is therefore IMPORTANT to pay attention when filling for the first time" it then goes on to tell you the capacities of the cylinders in ltrs. My system was installed by a motorhome dealer who filled the tanks so that they could then check it was working correctly with all appliances, thats what you pay for after all. The link shows an explosion at a gas station in Iran which probably bears no relation to refillable LPG gas systems! Lets hope the Iranian Nuclear Electric Generation system is a bit more robust!

thebishbus Posted January 25, 2013 Share Posted January 25, 2013 It overfilled in cold England above the 80% before cutting off, Then driving into the heat of Spain the extra gas expanded and was escaping through the relief valve. I phoned Gaslow they said this overfilling can happen on the first fill, but the relief valve will release any excessive pressure, but advised disconnecting the bottle and releasing the extra gas.

thebishbus Posted January 25, 2013 Share Posted January 25, 2013 pepe 63 If the 80% cut off valve did not work and if the relief valve did not open, the gas flow would turn off at the pump when the cylinder was full. That is the way the system works,for safety sake. Brian B. Link to comment Share on other sites More sharing options...

I bow to Derek's better knowledge, but the point is the same this was not in UK using UK certified equipment so not entirely relevant. D. Link to comment Share on other sites More sharing options...

Dr Dave Posted January 26, 2013 Share Posted January 26, 2013 All this discussion ignores the fact that the 'Balanced Orifice Over-pressure Measures' (BOOM) functioned as designed.. :D Link to comment Share on other sites More sharing options...

Thank You Derek, It was meant to be a Lighthearted Look at what might go wrong and i thought it would go down well seeing as a lot on here have Re-fillable Systems.
