Yes, I agree. Filling an aluminum tank so fast that it expands will cause a big boom!!! But then you don't need O2, any gas will do!!!!!

I am not pretending that heat can be removed. What I am suggesting is that less than80 degrees Fahrenheit is not going to be enough to ignite O2. Mitigate risk!!!!
In real life, if you for one moment think that an O2 clean tank, O2 clean transfill whip, O2 analyser or any other piece of equipment or particles in the air is going to stay 100% hydrocarbon free after a couple fills, you are fooling yourself BIG time!!!! Thus, is O2 clean kit really 100% clean all the time? I think not. Does each and every O2 clean tank blow up? Thank God not!!!!
Your equipment is not going to stay perfectly clean--but you try to keep it as clean as possible because there is no way of knowing without inspection how bad it is or what the threshold is.
No one is saying it is going to happen every time O2 hits a speck of contaminant, either.
This is very different from what you have been saying before, which is that it CAN'T happen. It certainly can, and it is a good idea to minimize those chances.

Inspection of a tank is going to give you NO idea whatsoever of the level of hydrocarbons in it, unless you have microscopic/bionic eyes, or an oil tanker ran aground inside your tank.
Lastly, I said you need fuel, heat and O2 to have a fire, fuel and O2 only is not going to cut it.

I'm sure glad you have all this figured out.
In the meantime, the rest of us will maintain safe practices and take care of our equipment. If you want to be a nickel rocket, go nuts. But please, keep your nonsense to yourself. While you're at it, make your own fill station.
Aren't you the same guy that tried to tell me that normoxic trimix isn't trimix? Your credibility is so low I have to dig to find it.

No matter how slow and even when you put a tank in a bath while filling it will still create heat. How much depends on the rate at which you fill. Do you really think that a tank doesnt expand under pressure???

I am pretty sure you can not fill a scuba tank with 100% pure oxegen.You can only fill a tank that is o2 cleaned.This is done by chemicals and detergants.It is to remove oil hydrocarbons etc.This needs to be done once a year.Only a tank marked for o2 not nitrox can be filled with pure o2.This is simple because a o2 only gets pure o2 not a mix.The seals I believe are different for pure o2 .The higher o2 mix has a higher risk exploding but not that much.But take the nitrox coarse and you will learn some good stuff.DIVE SAFE

See post 43 on heat.
One question on heat. Why dont the O2 tanks explode when they are delivered to my house on the back of the van, or when they are at the dive site? The sun bakes it during transport. We have heat?
I am really glad my tanks don't expand. Maybe thats one of your problems.
