watching the latest Deviant Ollam talk, they mentioned wondering if you can just trigger carbon monoxide sensors with some chemistry.Turns out you can just buy tester canisters! They're just spray cans of Carbon Monoxide! That sounds... somewhat dangerous. https://www.amazon.com/Sdi-Carbon-Monoxide-Detector-Tester/dp/B007886ZME

@foone i love that CONTENTS UNDER PRESSURE gets a front label warning but the fact that it's CO is presumably on the back with the other warnings

@NireBryce yeah! it's implied that this contains CO, sure, but I had to check the rest of the page to confirm that this is really just CO, not some chemical that the sensors are also sensitive too

@foone @NireBryce "nonflammable" seems wrong. A chemistry page says it burns with a "beautiful blue flame".

@foone I wonder what CO sensor manufacturers say? Local fire department told me a decade ago that CO sensors lose sensitivity to the gas by exposure. Putting one by a vehicle exhaust pipe to see if it worked was a bad idea & meant that a replacement was needed.

@foone have been subjected to this "non-invasive" co detector testing. that stuff stinks. very low odor threshold.

@michaelgemar I'm not good at chemistry type stuff but it depends how big a space it is. The recommended level is under 9 or 25 ppm, so it gets dangerous fast. 200ppm+ means you start getting headaches and nausea after an hour or two, 3000ppm means you've got mere minutes before headaches, 10-15 minutes before you're dead.

@foone @michaelgemar The company website shows using the canister with a cup-like device to test the sensor. I’m guessing the canister is something like 300 ppm, strong enough to trigger the alarm even when mixed 50/50 with ambient air, but weak enough to not be a hazard unless you start deliberately abuse it.

@foone I recall someone in my fraternity setting off the basement CO detectors by absolutely fumigating our basement with lysol.

@foone this disturbingly reminds me of Crichton's movie Coma (1978) and RObin Cook's novel of same name & plot.

@deviantollam yeah it's a perfect nerdsnipe to anyone who enjoyed chemistry class. Enough to make people overlook that you can just grab a can of it from Amazon
