OMG! What a dreadfully close call! 25 ft is not 2 atmospheres, but it's in the ballpark so the effect would be around 200ppm, yeah - yet it's more complicated than that. CO binds with the oxygen-transporting hemoglobin in blood and is released slowly, so on ascent when the PPO drops, you're at higher risk.
I bet he gets a CO tester and tests his own now! Well, I dunno - people surprise me at times.Usually the co analyzer is used before the dive.
Right, and so many don't know that compressors can indeed produce it internally, including electric compressors.Testing the air going into the compressor wont tell you if your compressor is creating co.
Damn, that's a bad setup, altho I have seen similar.The petrol powered compressor that filled this cylinder is mounted permanently into a van (truck). Its not a new compressor & the exhaust & intake locations are for want of a better word - compromised.
However, I (knowing the people involved) suspect that this compressor is run for too long & gets far too hot.
Well, none of us wanted to spend money on one I don't guess, but it's the only way to know if the tank is safe or not. Is a $300 price all that much more appealing than $400? Here is one for $339 including shipping and I guess the warranty is good, but you can ask Patty at Analox if you'd like.

Has he seen a physician? I really don't know if he needs treatment or not.And that is the main reason for the post...
If one person now takes air fills a little more seriously then this thread will have done its job.
My friend has had a headache for 2 days but is otherwise fine & the HSE has already been in touch - they seem to be taking this very seriously.
Just because it is filled by a 'diving professional' doesn't mean its not bad for you..
It's gets old and boring when tank after tank comes back at 0, no one else on the boat testing, until you find a tank that's not clean. Don't give up waiting for that one.Scary Scary incident. A a very good reminder to test EVERY tank before diving.
