Method Carbon monoxide megathread

[Artemisia]

Modern cars have catalysts and it's very hard to get enough CO from them. Coal does work but it requires some preparation and honestly, it's too much prep for me. Not to mention it's hard to tell if you have the required dose without expensive and hard to get CO analysers. If anyone is serious about ctbing with CO, I strongly suggest you learn about chemical ways to produce it, namely the GULPS system with sulphuric and formic acids or calcium carbonate and zinc.

This is an interesting possibility to be on the lookout for. Not viable as someone who lives with my mother in an apartment though, and would want a way that at worst draws zero attention for several hours and at best can appear as a complete accident; Have fun imagining me trying to sneak a barbecue grill into the house, bags of charcoal and gas canisters, then if I magically did but the attempt failed explaining why the walls of an entire room are black due to smoke

If it wasn't for that it would be very doable: It's very easy to place and light a barbecue grill in the bathroom with the window and door closed shut, no risk of a fire either even if it somehow fell over in the bathtub.

So question on this method...if you put charcoals in a tent that's in a shed, you run the risk also of being exposed to CO and going unconscious before you can get the CO up high enough? You just have to hold your breath every time you check the probe?

Also, is there risk of fire burning the tent, etc with this method, then starting a fire in the structure, even if the coals have died down? They will still be extremely hot. How long will it take to actually die? If levels are up to 10,000, but then you open the tent to let air in, how long is it going to take to get back up?

Would this just be better/safer to do outside completely with a tent/tarp if one could pull that off?

The TPI meter that is $431 is the only one I am finding that measures to 10,000. Are there any other options?

Anyone have an image of a good tent for this or make/model?

The probe is on a leadwire/tube, so run the meter itself to the outside of the shed for monitoring. Shouldn't be any issues with fire if you don't knock the coals over. Place the container on some bricks in the tent. You'll lose some CO getting in. Practice quickly getting in and closing shed and tent flap without CO first to get used to it. As far as how long it takes to get back up to 10000, you can practice that, too. Do a couple "live" runs simulating everything as it would be. When 10000 gets reached, hold your breath and simulate getting in and then watch how much CO is lost and how long it takes to recover. You can do it outside, too. I'll be setting up my tent in my garage, but I'm sure that's larger than your shed. Not sure what the $431 analyzer is, but I paid just under $300 for mine. Does yours have the number 707 in the model #? I think any decent pop-up/self-erecting tent with attached groundsheet and as few vents as possible will work. You need to seal any of the screening, maybe seams, too Throwing a tarp over it, too, is not a bad idea.

 

[Mircea]

Though it's highly unlikely I'll ever toy with such approaches, I still wanted to know if it's as simple as: Lock yourself in a small sealed room, set a bunch of coals on fire as if you were preparing a barbecue, go to sleep and don't wake up. If you have enough coals and firewood, wouldn't using say a small bathroom work just as well, no tent required? It might take a few hours to burn through all the oxygen but I understand the principle should be the same!

It's not that simple but it's not complex either. You should let the coals burn outside first, then when they're embers take them to the desired local. You should let the CO accumulate first, so that when you get in you'll pass out quickly, otherwise you may experience nausea, headaches, etc.

A small bathroom works great, the reason many people choose the tents instead is because they don't live alone or are afraid the CO escapes and harms neighbours.

Yes, that's the one I found but the price must have gone up.

So good news. When I put in that exact model, I did find a few for around $325. Do you know how the reviews are on these? If they are accurate? I haven't purchased anything because I am still researching whether this could be a method I could use. I don't get much time alone. After pondering, I don't think I can do it in my shed...I need to ctb away from my home, if possible, for the sake of my family. So I would need to get a campsite somewhere. CO does concern me, due to additional brain damage, which I already have. But then, every method I have available except N just sucks completely, IMO.

How did they kill themselves 200 years ago? My guess is that there were a lot fewer suicides. They didn't live as long and they didn't get injured like we do, due to pharmaceuticals, car accidents, etc, etc. So there was less reason to, even though there was still plenty of suffering.

Regarding the CO analyzer, they're certified to be accurate to a very small deviation, much, much more accurate than what we even need. As a matter of fact, even though I haven't used mine, yet, I already received a notice from the seller stating my meter is due for recertification. I'm not concerned with it. If I "top out" the analyzer, I'm positive I'll be good to go, even if it is off a small amount.

You have N available to you? I'd go with that. CO is very deadly. Each year many people succumb to it in their homes while sleeping due to faulty furnaces and plugged up chimneys, and I'm certain that the amounts they die from are far, far less than the amounts that (we) can purposely generate from burning charcoal and collecting the produced CO in a small space. The one thing those people have going for them is that they are asleep, so they don't even realize death is coming. It would be difficult to replicate that intentionally, though. The closest and easiest way is to get the CO level really high, so that we can replicate that "sleeping" state by rendering ourselves unconscious quickly, so that we have no idea of when death comes.

I think poisons were popular back in the day. And they were probably very painful deaths, too. I guess there were fewer suicides ages ago, at least by a total number count, but I'm not sure if the numbers would be that much less, if less at all, if you could calculate them on a per capita basis.

I wish I had N available...I would give almost anything for it.....you and I have conversed privately. I have very few options available to escape my torture. I am still just pondering my options to see what is doable.

I know there are hundreds of CO deaths each year and I know personally of someone last year, due to a generator. But still, there are thousands that are exposed that only get sick and damaged by it and that is what concerns me, since I have already had neurological damage to my nervous system and brain by an infusion. I did read of one guy on here who came back and his story was left. He got the level up to 6000 ppm in his car, fell asleep and 6 hours later woke up, only well enough to call his mom and go to the ER. He now has organ and brain damage. He's a young guy.

Yeah, you and me both on the N. I remember talking with you. Yeah, there are few options available, to anyone, really. All I can figure regarding the guy in the car was that the 6000 ppm wasn't maintained for very long. 6000 ppm should definitely kill someone if exposed to it long enough. Personally, I plan on several trial runs to verify my entire protocol and make sure it's repeatable. Definitely going to be timing how long to get the level to 10k, but also how long the level is maintained. I'll even simulate getting into the tent and resealing the flap and make note of how long it takes to regain the 10k ppm level.

All I can add is that in the case of CO more is always better! For those of us serious about using this method it's essencial to experiment and make sure there's a high enough concentration and that it'll hold for some time (the higher the concentration the lesser the time).

 

[calculusmaster]

hey I was wondering if 4kg of coconut charcoals made for hookah smoking in a 3m by 2m by 1,4m room (2m² i think) would do the job.
im planning on using a hookah coal burner until they're glowind red and put them in a bucket and get in the room whilst also taking 2 flurozepam and drinking a shot of vodka.

can i just wing it if i know the theory?
im going to use 10 kg of charcoal lumpwood in a small polyester tent with a tarp on top of it.
i have the chimney starters and metal buckets.
im just afraid the heat might burn the polyester.

I obviously don't know if winging it will work. I've never tested with coal and, especially, with a tent, as I prefer the chemical way to generate CO. I hope it works, 10 kgs should be an overkill, but I have no idea about the heat, it'll most likely damage the fabric.

i read a post on here from a chemical engineer that just 3 kg is enough to produce 9000 ppm in 40 mins. ill try 5 kg. i just hope that knowing the theory behind this method is enough for me.
ive been trying to find a co analyser but none so far.

The theory is that a pound per m3 should be more than enough, some people consider using 1kg/m3 to be absolutely sure, but that comes with the additional heat.
How big is your tent? Try to calculate how many m3 of air you'll have inside and do the math from there. I can help with that if you need it.
Keep in mind 10000 ppm is actually equivalent to 1% of CO in the overall volume of air.
It really sucks how hard it is to get analyzers that can do that, I can't find them either, which is one of the reasons I chose the chemical way. Unfortunately, it's full of issues too.

the tent is 247 cm (L) x 148 cm (W) x 112 cm (H). can u help me find the volume? im really bad at maths.

You just need to multiply all those numbers, so it comes to 4,09 m3. So, theoretically, 4 kgs should be more than enough. It should account for how much carbon is in the coal/pellets you're using and be certain that no matter what you use it'll be enough. Of course, make sure it's (nearly) absolutely airtight.

You have to multiply all those numbers, that room has 8,4 m3! Since the "safe" number is about 1 pound (450 gr) per m3, 4kgs should be enough. But always make sure to be on the "safe" side.

I actually measured it wrong lol thanks.
the measurements are 1.2 meters length, 1.4 meters width and 2 metets height soo around 3.4 m3?

any tips for this?

Unfortunately I don't know a thing about tents. All I can suggest is read the label if you're buying one, do some testing... Try putting something really smelly inside, close it tight, and check every half hour if you can smell it outside. If after 2 or 3h you can't smell anything, it should be tight enough. There are also impermealizing sprays that shouldn't be hard to find, but I really don't know if and how they work on tent fabric.

What if that smell doesn't go away easily after the test? (From inside the tent)

Why not just use a smoke bomb, or even dry ice in water might tell you enough. You're never going to make it 100% sealed. Throw a tarp over it to help contain CO. It doesn't have to be 100% airtight. You only need to be generating more CO than you're losing. Use 4X the amount the calculations tell you to. More charcoal is ALWAYS better.

Well, shouldn't be something really terrible (maybe a few rotten eggs or rotten potatoes in a dish/cup) and it should be done before the final day, so that you can turn the tent inside out and let it aerate for a while. I advise against leaving testing to the chosen day.

My nationality is showing! Smoke bombs are banned in my country and dry ice may be available but not common at all! So I never considered them, but good ideas of course!

I did this very recently. Think it was my 3rd effort. I panicked and called emergency services myself. My co levels were really high and so the paramedics put me on cannula oxygen and mask. Aside from the panic it is pretty easy to set up. I did it inside a tent - I would try again

Are you measuring it with an analyzer?
What kind of pans is the charcoal dumped into on the bricks?
