No it doesn't, there was only minimal corrosion from Fresh Water, and last I checked, there's no way to get salt water in a tank from a "wet fill". LOL
That would be a really neat trick from a compressor. Try AGAIN!
Bleed old air from tank?

Re-read your post...Your question was (and I quoted it on my post) "what research facility?". That post does answer that question. It tells you it was The University of Rhode Island.
I should have expounded on my question. My question in essence is...
What research facility showed a negative result from a wet fill that resulted in hazards or death.
Granted, 200ml of SALT WATER in a tank could create a hazard, but show me a research facility showing a wet fill from a compressor duplicating the same results.

Actually the article says O2 content was reduced TO 3%. I found the full text of the article in one of the linked posts
Anyone who STARTS a dive with only 300 psi already has pretty questionable judgement - for all we know the tank was last filled at a gas station air pump
I'm taking no position as to whether one should or should not drain and inspect their tanks every 3 months but this seems like a 1 in a million type of situation to me, hardly solid evidence that the practice is necessary.

I would also like to know that. I am not aware of any.
His post does explain the URI basis for choosing 500 Ml as a control quantity of water for the test. It was not "mimicking" a wet fill but rather water entering via 1st and 2nd stages of the regs thoughout dives.
"...Water has been known to enter scuba tanks through the second and first stages of the regulator. URI took an empty diving cylinder with an attached two-stage regulator to a depth of only 10 feet in a swimming pool. They pushed the purge button ten times. Later, after removing the cylinder's valve, they found between 195 and 211 milliliters of water in the tank. URI therefore decided to use 500 milliliters of water in their tests described below...."
Knowledge is key, then you're free to make your own decision, that's what it's all about. As long as you know what can happen and what has happened, then you can make intelligent decisions for your self. That was the whole point of my entire write up as previously quoted.
In fact, as a result of the research that I quoted, industry (such as the Compressed Gas Association, Professional Scuba Inspectors, etc.) now make "best evidence" recommendations for cylinder inspection, testing and storage. And, in fact, we have annual scuba cylinder visual inspections as the result of recommendations from the Battelle study. It's nice to go back to the review the original data to find out where all of these procedures and recommendations comes from.
LOL< your thread says the air in the tank had reduced oxygen content by 3 percent. That's 18 percent left in the tank? At the surface, our bodies only require 16 percent to support life. Underwater, we require even less. I'm starting to question your knowledge on the human life.
If I'm reading this correctly, he (Doc Harry) said the air in the tank had reduced oxygen content TO 3 percent, not BY 3 percent.
On an empty tank? Sure, on a tank with more than 140psi? Not possible.
Again, salt water did this...
When have you guys ever heard of a wet fill that resulted in salt water? The document said that the decay in fresh water tanks was minimal.
Now, if you are going to argue that if you get salt water in your tanks that this is possible, then I'm going to concede that fact, if you concede the fact that if you bleed your tanks to 0 and don't do an inspection, you are dumb deserve what you get.
