[VIDEO] Dumb Youtuber makes "lifehack" video telling people to cool their room with chilled carbon d - General

This little bit of Dry Ice wouldn't do shit to you. Double the amount and be trapped inside a car with it and then it might. This amount would probably make it hard for a pet to breathe if it were a small room maybe

Put some dry ice in the back of a car's exhaust pipe and duct tape it shut. The perfect crime.

It's no different than going to your garage, getting in your car, starting it up, and rolling down the windows to slowly await death. You end up breathing more CO (or in this case, CO2) until you eventually pass out and suffocate. This is actually considerably more lethal because of the volume of CO2 it is pushing out. At least with suicide by carbon monoxide, it's only coming out of the vehicle exhaust, and it's not blasting in your face like this abomination is. CRH would have made a pretty good Nazi.

Concentrations of 7% to 10% may cause suffocation, even in the presence of sufficient oxygen, manifesting as dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour.[/QUOTE] [QUOTE=http://en.wikipedia.org/wiki/Carbon_monoxide]Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin. A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality.[/QUOTE] (Video in OP is still a very bad idea though)

[QUOTE=Quiet;45425300]Difference being that carbon monoxide is quite toxic while carbon dioxide is not so much: [/QUOTE] You could very realistically pass out from this thing running for too long. If you do pass out, there's no way to shut it off. If you can't shut it off or move to leave the room and get fresh air, you could very easily suffocate while sleeping away. That's why this is so dangerous. It's like putting a plastic bag around your head, only it takes longer to kill you.

You are right about this being very dangerous.

the biggest thing about gas is that no matter how harmless something is, no matter what, all you need to do is have enough of it that it will displace oxygen in the room or even merely in the lungs and you are completely [B]screwed[/B]. it's the invisible killer. And that's why Co2 is so deadly. it replaces oxygen and you couldn't be any the wiser. if you ever weld TIG never do it in a contained area because the gas will basically kill you. When playing with non-oxygen filled gasses 100% of the time you should be using a fan unless you know what you're doing.

Did he really try to justify his air conditioner with an annotation and a link to "dryiceinfo.com/safe.htm"? [quote]VENTILATION - Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide in the air rises above 0.5%, carbon dioxide can become dangerous. Smaller concentrations can cause quicker breathing and headaches but is otherwise not harmful. If Dry Ice has been in a closed auto, van, room, or walk-in, for more than 10 minutes, open doors and allow adequate ventilation before entering. Leave area containing Dry Ice if you start to pant and breath quickly develop a headache or your fingernails or lips start to turn blue. This is the sign that you have breathed in too much CO2 and not enough oxygen. Dry Ice CO2 is heavier than air and will accumulate in low spaces. Do not enter closed storage areas that have or have had stored Dry Ice before airing out completely.

The way TF is calculating the dangers of the dry ice seems a bit off, simplifying it way too much. I'm running the numbers myself and I'm getting around 5% volume concentration. (In a room that's 5x5x2, like his example and 5 kg of dry ice). Not in the lethal range, though you won't have a good day sitting in that mix of gas. In my opinion, this is relatively safe if you just have leave a door open or something, but if you do that you might not even notice the bloody thing cooling anything. Still seems like a dumb idea, might as well use something like ice, you know, something that can't fucking murder you. (Usually)

Any gas in more concentrations than normal levels is potentially dangerous [B]because it displaces what we are physiologically dependent on breathing.[/B] edit I'm not denying the toxicity or lethality of carbon monoxide. I know it's dangerous. I was just saying that, in this particular example with a device that shits out carbon dioxide in a small enclosed space, it would be more lethal than sitting in your car with the windows down and awaiting death by exhaust. That takes a few hours. This could knock you out in around half an hour, and after that, you'd be unable to move until, eventually, the carbon dioxide content is so high that you aren't getting enough oxygen. You would just suffocate in your sleep. The same thing happens to people who commit suicide with helium. The helium displaces enough oxygen to cause them to pass out, and eventually, helium is all they breath and they expire. This dry ice cooler is no different.

hah, he added this: [QUOTE] VENTILATION - Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide.

[QUOTE=bloboo;45422842]I love that the guy gets his friend to lay down in all the dry ice smoke or w/e it is, his friend coughs and says "yeah you can breath its just you're breathing not good stuff" and the youtuber is like "no you can breath it"[/QUOTE] Well, he's right, you [I]can[/I] breathe it but you will probably suffocate.

[QUOTE=SFC003;45437283]hah, he added this:[/QUOTE] what he should do is remove the video entirely

Place plants in your room, problem solved.

what's up with the "Safety is number one priority" slogan or whatever when he does stupid shit like this really what
