As far as your question about the operation of the 'Canary Gauge' is concerned, as Safety Officer, I should know this, but have never actually looked into it. I had assumed that it was calibrated to 100% equals 50% fatality rate (the usual measure of 'lethality'). So, I would think that the 3% concentration level that you mention is, indeed, the 100% point on the scale (after all, not much point showing the equivalent of 5 or 10% CO2 concentration, as it goes without saying THERE WOULD BE NO-ONE AROUND TO READ IT! I've had a couple of confined space issues. Once when an arrogant Chief PO ordered a BIG Tongan welder down into a pit to clean it with no breathing or recovery tackle - it had been full of acid-based paint-stripper fumes, so, naturally, he collapsed. He wanted to order four more of his ilk down there (can you imagine trying to get one of those 300 pound warriors out of a hole in the ground?). They were going to do it too, until another CPO, who, thank the Powers, happened to be passing, intervened. I've never seen a screaming match like that, but eventually the idiot backed down and allowed the rescue team to do their thing with proper gear. Only one bloke in hospital for a week with respiratory and acid-burn issues, instead of 3 or 4 dead. Lucky. But, I've only had one encounter with CO/CO2 I was an idiot. Or, more kindly, ignorant of how quickly things can go wrong. It was winter in Sydney and we had no serious heating in the apartment. We naturally had all the ports & hatches fast-tight. We had a tiny Japanese Hibachi B-B-Q. We'd done some teppanyaki and gone to bed. I'd decided to just leave it to burn in the dining room for warmth. A couple of hours later, I woke with a splitting headache, like I'd never experienced before. I tried to wake my wife but couldn't get anything sensible out of her - she was in trouble, too. In my stupor, I was having great trouble working out what was going on. Luckily, I fairly quickly figured out that it was the B-B-Q, so opened everything, and put the thing out on the balcony. It took us an hour or so to recover. I have no idea what concentration we reached (I still find it incredible that a couple of hands full of B-B-Q heat beads could generate enough to fill a two-bedroom apartment sufficiently to give us such a scare), but it certainly gave me a whole new respect for the Silent But Deadly class of Confined Space risks!
