my biggest fear is to hurt someone else by accident, and i've read articles about charcoal-burning suicides, where someone finds the dead body,
and then they accidentally pass out from the smoke and the carbon monoxide.

so my question is...
if my tent is 100% airtight, and i successfully suicide in there, and nobody finds me until maybe 2 days later...
a lot of the carbon monixe would have evaporated or whatever by that time, right?
or does it just stay perfectly preserved inside the tent?

you would assume that as time goes by, the less dangerous it becomes to open the tent.

i know i'm not articulating this very well, it's getting really late in my country and i need to sleep.

i'll probably wake tomorrow and be like "what the fuck was i even trying to say?"

but hopefully it's somewhat understandable lol

Definitely within a couple days all CO will have dissipated. More likely within several hours. Put up a sign warning others of CO hazzard.

Hi there,
This is my own much-preferred method.
I confess, I've not particularly researched this aspect of it, as common-sense tells me it's not an issue - If you think about it, your tent has to be ABSOLUTELY airtight, and it will still take time for the charcoal to put you to sleep, therefore, even if your tent is stuffed full of carbon monoxide, when someone unzips the flap (and I'm guessing your tent will be outdoors), they will get the mildest, most fleeting/diluted breath of carbon monoxide, will see what's happened, and call the authorities who know how to deal with it.
If you think about it (again!), for it to do them harm, they would have to open the flap (thereby letting in loads of oxygen/letting out loads of CO), climb in with you, zip flap back up again, and sit and wait for the carbon monoxide to take affect... which would probably NEVER happen due to all the oxygen they've just allowed in/CO they've allowed out!
I'm open to being corrected here, but, as I gather, when done outdoors, the CO will just dilute so quickly when your tent is open, there's no risk to others whatsoever (although, this may be different if you did it indoors...).
Much love! :)

sounds about right, and i think that's true. that when done outside, there will be no risk

i just have to make sure i'm elevated higher than the charcoal itself, because i saw something about that.
somebody did it and failed, and it seemed like he failed, bc the gasses didn't go into his nose as well as they could have,
if he was elevated above the charcoal.

Does anyone have a link to more info on a tent CO2 method? I've heard about CO2 being used, but wasn't sure how to produce the gas. I hadn't thought about a tent but it sounds like a good, accessible idea

charcoal is what produces co2, right? i know it produces carbon monoxide, but i'm not a scientist, idk all these molecules or whatever.

Yeah that's what I heard, at one point I thought about buying a load of disposable BBQs and burning them all, then I realised it would set off the fire alarm. I hadn't thought about doing it in a tent. But like you said, I don't know if it would cause the tent to melt now that you mention it

i heard that it's when the charcoal starts turning white, that it releases the gasses.
so i think they say you're supossed to let it burn for maybe 30 mins and THEN utilize it for suicide

CO and CO2 are entirely different gases. Burning fossil fuel produces CO (incomplete combustion). You expel CO2 after breathing in air. Breathing CO2 brings on the hypercapnic (panic) response.

im gonna need you to talk to me like i'm 12, with the scientific stuff.
but just tell me, when we burn charcoal, which gas is produced?

when charcoal is burned, carbon monoxide is only produced when the smoke is gone and the coals start to turn white and glowing. two of the reasons you need an air tight space is, 1) you don't want the produced carbon monoxide to escape, and 2) when carbon monoxide mixes with oxygen, it produces carbon dioxide, and carbon dioxide will bring you pain and suffocation feelings.

so you can pretty much go by that?
that when there is no more smoke or at least very very little smoke left, that's when the Carbon monoxide starts getting produced?

and do you know if there are certain charcoals better than others for this purpose?
and how long would you estimate the carbon monoxide keeps coming?

From experience this is unessacry lol. But in a tent the extra heat from when charcoal is starting might melt/set the tent on fire :p

Burn the charcoal low and slow and you'll produce carbon monoxide
and do you know if there are certain charcoals better than others for this purpose?

Use lump wood charcoal because the fumes are more palpable. For carbon monoxide production it doesn't matter.
Carbon monoxide keeps being produced as long as there is charcoal left to burn.

ok thanks for the answers, but what does "burn it low and slow" mean?
Like you wanna limit how much oxygen the fire has access to. So like you don't want air being able to flow in from underneath the fire and you don't want it to be like billowing or anything. Just keeping it in a pot is enough tho. I used a cast iron pot and had it burning in that and i got to the point of almost passing out in 30 minutes

I wonder if you could stick a tube to fresh air to breathe through as it builds up and then plug the tube when levels of CO are super high. Might get knocked out faster? also if you produce carbon dioxide by breathing out wouldnt this solve that issue because you would be breathing fresh outside air until all the oxygen is gone from inside your area? no carbon dioxide to inhale assuming the area is airtight

so do you keep the lid halfway on the pot?
and omg really? (about the 30 mins) :O
that sounds powerful.

do you know how long it takes to die from it?
and if you want, could you elaborate a little bit on when you did it?
was it a test run you did?

Nah i just left it fully open. I have photos from.it too. My SI told me it wasn't my time yet so i crawled out and breathed. It took about 6 hours to fully recover from it tho lol.

interesting post, thanks.
so you turned it on inside and let all the smoke occur inside your bathroom? is that what oyu did?
how come you didn't let it burn outside and then bring it in?
even tho it's better to do it outside completely

I am lazy and couldn't be bothered + i love the smell and feeling of smoke entering my lungs. Also it doesn't effect carbon monoxide production
