Oh what a coincidence a confined space death http://boston.cbslocal.com/2016/12/15/braintree-water-tower-rescue/ No word on what went wrong besides diving equipment issues and industrial divers have the biggest balls. But the following action makes me think they maybe weren't 100% in training. quote:A spotter jumped inside the tank to try to rescue his co-worker when he noticed something was wrong, but he was quickly overcome by the 45-degree water.

Speaking of closed spaces with asphyxiation, I can tell you how distilleries can have way open floor plans but you can still be deprived of oxygen. The mash is created by adding ground corn, rye, and barley (for whiskey) to water and mixed in giant tanks. Yeast is added and they go nuts in the sugars converting it to alcohol and lots and lots of CO2. These are large vats (Buffalo Trace has vats that are several stories tall and about 40 feet wide) but the yeast quickly multiply. The CO2 vents off but they are making so much of it the space between the lip of the tank and the mash is totally deprived of oxygen because the CO2 keeps being made and pushing it out. Tour guides let people smell it but will warn to not go below the lip because if you go below pulling in air into your nose is also pulling in a lung full of not-oxygen.

I thought it meant 45c for a moment there and was terribly confused. Like, the water was so nice he just relaaaaxed until he ran out of air. Like that video of a kitten that keeps getting back into a sink of warm water, only not as funny.

Confined Spaces: A quick and totally and utterly non-comprehensive guide The problem with any small space is that humans can only breathe air, specifically a gas that contains 78% Nitrogen, 20.9% Oxygen, about .05% CO2, and not much else. If any of those numbers start changing much, particularly the O2 levels, humans start getting messed up. O2 particularly can't vary outside of 19.5% to 23.5%. The legal/safety term for this kind of thing is IDLH, Immediately Dangerous to Life or Health. i.e. anything that will kill you, which it turns out is anything that's poisonous, reduced or enriched in oxygen, or really anything other than standard sea-level air. Oxygen deprivation is a huge problem, because humans have a sense for "I can't breathe". It primarily deals with CO2 though, not oxygen so much. Also you can't perceive a lot of gases at all. That means that it's 100% possible and actually every-single-day common for a person to get into a confined space, feel fine, then collapse with no warning. It'll do the same thing to anyone else who comes in, too, so if you want to go in after someone you better have a source of clean air. This happens every day. -Reduced O2 caused by: decaying material, rust, cotton (turns out cotton is oxygen-hungry and will soak it up given the chance, like in a shipping container), any chemical reaction that consumes O2, any gas being supplied in a small area will change the ambient gas makeup and will kill you. -Hydrogen sulfide ("rotten eggs" gas) has the lovely combo in that it smells awful, but then promptly blocks your sense of smell. So you only smell it for a moment. Also it can kill you in sub 30 minutes at 400 ppm. Given off by rotting material, sewers, and many industrial processes. Also explosive in addition to being straight poison. -Nitrogen. Really common in industry since it's inert, you use it to keep stuff from rusting. Couple percent too much and you'll just fall down unconscious. -Carbon monoxide. Those are the super-common everyday ones but rest assured that anything will kill you if it displaces the oxygen. Also too much oxygen will give you oxygen toxicity and impair your judgment and thus ability to self-rescue, too little oxygen will impair your judgment and ability to self-rescue, and everything changes like crazy if you're breathing compressed gases like when you're diving. Basically if there is a sign or warning saying "Confined Space - Do not enter" then stay the gently caress outta there. Unless you know exactly what you are doing and have air monitoring, a rescue winch set up, and someone watching you who also knows exactly what they are doing and also has a supplied-air respirator, the slightest thing going wrong will result in the person who went in and possibly many more people dead.

Except all those times that municipalities ignore the engineering suggestions and set speed limits arbitrarily. A lot of larger cities will have some mechanism where you can request a traffic study to get a speed limit adjusted, but good luck with that in rural areas that get a substantive portion of their revenue from ticketing drivers passing by.

Odd bit of science history, but it was Joseph Priestley messing around with the "fixed air" (CO2) that was produced above brewery vats that led to drink carbonation and, eventually, the discovery of oxygen.

Uncle Enzo posted:O2 particularly can't vary outside of 19.5% to 23.5%. What's important is the oxygen partial pressure, because oxygen becomes toxic at higher pressure. 2 bar oxygen partial pressure is usually seen as the maximum limit. In diving you never go above 1.6 bar, which means that with 100% oxygen you don't go deeper than 6 meters, and with 36% Nitrox you don't go deeper than 34m. (34m = 4.4 bar. 4.4*0.36 = 1.58) And on the lower end of the scale, many gaseous fire supressant systems are tuned to leave the O2 concentration around 10-12%, which is enough that you won't run an immediate risk of dying, while being too low for a naturally aspirated fire to sustain itself. You might pass out and you should definitely leave the area if you can before the system goes off, but if you can't and there's an uncontrolled fire in the room at least the suppressant is a lot less likely to kill you than the fire is. I've also been told that the reason Argonite contains a few percentage of carbon dioxide is specifically to trigger the gasping reflex, so if you're stuck when the system goes off you'll gasp for air and get more of the residual oxygen into your lungs.
