I don't know why anyone would be refilling a gas canister inside an enclosed room. There must have been a flame source like a pilot light in that garage to ignite the escaping gas.
@@RazorStrap Myth busters actually tried to ignite propane and other things, simply by rupturing the metal, and couldnt get it to ignite. So they tried including essentially fireworks, and it still wouldn't ignite. You need more than just a rupture...
Doing a lot of off grid stuff the past five years I’ve been refilling those all that time probably 100 to 150 refills without issue. I have seen one or two of the 1 pound takes expanding or expanded which caused me some concern but they still functionedmay not use those again since they are already stretched out
None of what you said makes sense. Propane can only generate so much pressure before it becomes liquid. The bottles are rated for pressures well above that. Why would you get rust on the inside of the bottle? There shouldn’t be any oxygen in the tank that is necessary to cause rust. If oxygen is mixing with the propane inside of the tank, you have far worse things to worry about.
By that logic you should stop driving a car, because things happen, especially when one isn't careful. Make sure to never fill indoors. Always away from any ignition sources Make sure to weight the tank to prevent overfilling. There's should be no reason for the tank to explode. They've been rated to withstand 1lb of propane easily
They have not been rated for repeated pressure cycling. Same arrogance as doomed Oceangate sub. Disposable tanks are thin wall aluminum. Repeated stress of pressure cycling will cause it to fatigue and explode. There is no need to be a Darwin award winner.
The guy may have been filling his 1-pound propane tank in his garage with the garage doors closed which may have caused some of the escaping propane gas to ignite from a spark such as static electricity. Additionally, the 1-pound propane cylinders also have a pressure release valve which should have prevented the propane tank from exploding, right?
@@RazorStrapdude stop speaking you are just spreading misinformation around and calling others people unintelligent when you are the one who doesn't have their facts straight. The real reason they say no refill is because they make MONEY selling you more tanks of gas instead of letting you refill them yourself for penny's they want you to go spend another $8 dollars on a new tank and further pollute the planet rather than let you recycle. They are greedy jerks and they are STEEL tanks not aluminum...

If it was so thin that it wasn't designed to be refilled how did it get the propane in it in the first place? And how on earth Could they be sold in the first place if they're so Dang dangerous.
Can you find anything that documents that anyone has EVER been prosecuted for refilling a disposable tank, probably not. I don't agree with everything this guy said, but in the end there are legitimate safety issues with refilling these things and there is little reason to do it now that there are tanks designed to be refilled available.
@ I agree, but I don’t like the idea that if they wanted to, government can seriously harm you with this. It’s not that I think it will happen to me, it’s that there are many things in our laws that people are grossly unaware of that can destroy our lives. That’s what worries me. And it’s not that I don’t think these regulations shouldn’t exist, it’s the egregious penalties that shouldn’t exist.
@@oneisnone7350 I understand. I think that the law is intended that these things don't get refilled and transported commercially. It could certainly be dangerous. I wouldn't want to be caught with a tractor trailer load of them intended for resale. If the fine was just a couple of bucks there would be black market bottles everywhere.
Refilling your vehicle and cause an explosion. Having your 20 lb tanks refilled at the hardware store can cause an explosion. Any time you transfer flammable materials you run the risk of explosion.
Yes. US-DOT has approved them for 12 years. Like the larger tanks, they are steel. Not thin wall aluminum. Can handle the pressure cycling. Thin wall aluminum will fatigue and explode. Lot of people posting in here are making excuses for why it exploded not having anything to do with that it was a disposable. But they simply don't know and are going overboard with speculation. They do not know how many times that tank had been refilled. But even once it could fail. It is not structurally designed for that. Don't do as they do. Do as engineers and manufactures have told you how to safely use/NOT use their product. The risk/reward/savings is beyond absurd. Risk life for a few dollars. Absurd.
Replace cheap ones periodically and not refill indoors would be the common sense approach…. This seems as a product commercial and sure enough the Amozone has the mentioned products readily available.
Common sense can be dangerous and just flat out wrong. Once upon a time common sense was that the world was flat. People were even killed over round vs flat. True sense would be to heed the manufacture's safe use instructions not to refill that tank.
Take a magic marker and indicate with arrows marks on the bottom of the 20lb which way you turn the knob on and off. Open and close fully. Alway used a filter on everything. And clean the rust off all threads. AND NEVER DO THIS PROCESS IN IN A ENCLOSED SPACE. Be safe.
polk county florida, where i live. the guy probably was refilling an old rusty tank that was sitting beside his garage for 20 years while he had it facing his lit bbq 2 feet away while inside an enclosed garage. people here aren't the smartest tools in the shed. incidences like these are probably unlikely to happen in normal circumstances.
I've watched several of these videos. On one the guy cut a cylinder in half and exposed what appeared to me to be superficial rust on the inside of the tank. Then he stated that that particular tank had been "empty" for years (exposed to air?). I am not convinced that a tank that has not been purged with air would ever rust in that I don't believe that propane is corrosive. (Humid air certainly is.). I Don't believe that corrosion or over pressurization is the issue with these. I have refilled several however that leaked out the over pressure valve which could be dangerous if the can were stored in an enclosed space. I usually let them set outside fore a day after refilling and check them with soapy water
They can be refilled many times safely. Literally hundreds of thousands of people are doing this on the regular and one single incident means they can't be done safely... That's like saying you shouldn't go hiking because you could get attacked by a bear.
The explosion/fire would have been much quicker with a vented Fuel Keg! The Fuel Keg is far superior for refilling, but the rupture was caused by combustion from using a flammable gas in an enclosed space, the results would have been the same either way.
If you are weighing the tank and ensuring it’s only getting 1 pound of propane I’ll take my chances filling them! I do agree the refillable tanks are a better choice but the others in my opinion are fine if you know and understand how to properly fill them
I refilled the disposables for a few years. Eventually the fitting would get rusty and not seal to my stove, or the valve would start leaking a little. It just became a hassle. Not to mention needing a temperature differential between the 20# and the empty. Flame King came along and I haven’t looked back since. And I have piece of mind that I’m being as safe as I reasonably can be.
Disposable tanks are thin wall aluminum. Repeated stress of pressure cycling will cause it to fatigue and explode. There is no need to be a Darwin award winner.
