Carbon Monoxide kills two - Eforie, Romania

He was not very receptive to listening from me.

Take some solace that he's been embarrassed ever since he found out that you were right. Every time he thinks of it and every time he checks his air, he'll always think of you and blush again.

Got to wonder where the pair of divers got the bad air. Did they do their own fills?

Many very accomplished divers don't test their tanks, as they didn't.

I don't test my tanks. I get my fills from only 3 sources. All are high volume, very reputable South FL dive shops. If I were a traveling diver I would probably spring for the cost of a CO detector.

I don’t test my air, but my shop uses electric compressor to fill their bank.

Electric compressors can also produce CO.

Electric compressors can also produce CO.

Just to expand a little, lubricated compressors can generate CO internally by over-heating lubricating oil through heat of compression, cooling system failures, contaminated oil, etcetera. Even high-purity non-lubricated compressors "can" pump CO if any reaches the intake.

What percentage of divers check air? Do nitrox gauges also check for other gases?

Not enough, and no - not at this time. Divenav did make one that checked O2 and CO, but they couldn't run a business.

I've posted here on Scubaboard before that once, when I was preparing for a cave dive, I tested my tanks for CO and the device indicated 18ppm CO. As most people there that day had filled their tanks at the same place (the only dive shop within 100km), I thought I should alert other divers nearby and offer my CO analyzer. One diving instructor near me refused using the device, saying that it was not necessary because he did not smell anything wrong in his gas.

I know, I know.

Denial is a not a river in Egypt.

Yeah, news sources fail telling enough of the story.

I don't test my tanks. I get my fills from only 3 sources. All are high volume, very reputable South FL dive shops. If I were a traveling diver I would probably spring for the cost of a CO detector.

YOU SEE. He should know that is not a safe and dependable approach, but he believes the lie.

I don’t test my air, but my shop uses electric compressor to fill their bank.

And he should know that overheated electric compressors produce CO internally burning their lubricating oil.

So many divers just do not want to believe facts that will cost money. The agencies and DAN have failed us on this, so we'll keep seeing these stories.

Not following. What lie am I believing? To me it's a risk management decision. COULD the fills produced by any of these three vendors have CO? It's possible. How likely is it given how these shops are run? I believe it is extremely unlikely. To me the risk is low enough to not warrant a $400 analyzer that requires a $200 replacement sensor every 2 years or so.

My Sensorcon cost about $125 and lasted 6 years before replacement. Works well and price is still about the same.

Interesting. Is this the one?

Portable Carbon Monoxide Detector Meter (CO Inspector)

That's what I have.
