final CO questions

[LilysAngel]

*I am really bad with numbers and math. I see there is an equation to determine how much charcoal to burn. My tent measures: 86.7"L x 37.4"W x 47.2"H
How much charcoal do I need? I plan on using two grills, each with the recommended amount. So ideally I'll have 2x what I need. Just to be sure.

*Is using hardwood charcoal lumps advisable? I saw one success on here with this. But no other info. If not, what's the best type to use eaisly accessible in the us?

*some people mention using water in the bucket they transfer the coal too. Wtf does this do? Any more info on this would be appreciated.

* I need to set the buckets on bricks once they're in the tent, yes? So no fire starts? Do I need to put holes in the buckets? What does the bucket need to be made of?

*Are there any other methods or things that can be added to this method to ensure success? I like having a backup plan. Would love to drink SN prior, but cannot find a source.

* I will put up warning signs for whoever discovered. Both to warn of CO and a body. To not look & call authorities. For safety, are there any other preventions i should take to ensure nobody else is harmed?

Thank you all so much for your help. Any advice would be very appreciated.

Are these tent measurements in inches?

LENGTH 2.20 meters or 2200CM
WIDTH 0.94 meters or 940cm
HEIGHT 1.19 meters or 1190cm

 

[LilysAngel]

Yes, these are inches.

 

[Darkover]

Yes, these are inches.

what's the recommended amount of coal per square meter or do you know where to find that information needed

I'm not telling you what to do specifically but if it were me I know i would use a huge amount and I would know not to get too hung up on the particulars. People mostly want to use the dimensions to find out the minimum, but 15 to 20 lb charcoal it would be more than enough for any tent van car or otherwise. I would also tape over any windows

This is quoted from another post in the megathread

"The calculate the minimum required amount of charcoal which is 0.135 kg/m³ and double that amount."

lump charcoal is suggested

*some people mention using water in the bucket they transfer the coal too. Wtf does this do? Any more info on this would be appreciated.

Afaik you don't put water in the bucket but under it, otherwise you would extinguish the coals. This is to reduce temperature of the space you are in, I assume.

* I need to set the buckets on bricks once they're in the tent, yes? So no fire starts? Do I need to put holes in the buckets? What does the bucket need to be made of?

yes onto anything that is fire and heat resistent otherwise the tent bottom might melt.

* I will put up warning signs for whoever discovered. Both to warn of CO and a body. To not look & call authorities. For safety, are there any other preventions i should take to ensure nobody else is harmed?

are in in a multi story apartment building? That could be a danger for other people in flats nearby.


I would use minimum double the amount of charcoal that is minimum suggested.

2.20*0.94*1.19==2.460
135/2.460 == 54kg
or
0.135/2.460 ==0.05kg

Thank you so much for taking the time to read & respond. I really appreciate it.

It'll be in the woods, in a tent, far from people.

Also, is HARDWOOD lump charcoal okay?

2.20*0.94*1.19==2.460
135/2.460 == 54kg

Sooo how many pounds would that be? I tried google conversion but it was like over 100lbs. Which definitely isn't right.

Outside in the wood a warning sign at the tent will do, by the time you'll be found there shouldn't be any serious concentrations of CO anymore, the tent won't be 100% airtight. But a warning sign is important just in case.

I would say yes, any kind of lump charcoal, but not charcoal with lighter fluid/additives or so that can cause unwanted emissions that cause additional irritation, afaik.

A 10k PPM CO meter can be helpful if you have one at hand. To measure the concentration of CO but it's not a necessity.

or this maybe
0.135/2.460 ==0.05kg double it to 0.10kg to pounds is 0.22

That is correct. If you work out all the calculations based on your tent size (I haven't), you will find that you will need considerably less charcoal than an 18 lb bag. I'd use the entire bag anyway. Small metal buckets. You can drill some small holes around the periphery of the bucket near the bottom to ensure continued combustion. Some use small grills. Either will work. Yes, placed on bricks. I don't know what the water is for. I'm not using water. 100% carbon lump charcoal is best - maybe brand RO? Let all the impurities burn off outside tent until coals are red/white hot and not smoking. Then buckets, or grills, go into tent for 20 minutes, maybe 30, to allow CO to build. After appropriate time passes, then the "CTB-er" gets in tent. Need to hold breath while getting in tent and closing/sealing "door". Then start taking breaths.

Whomever decides to utilize this method, or any method really, needs to make sure they really, TRULY want to ctb, because this is DEADLY SERIOUS STUFF.

This method probably isn't the best one for a "do-over", either, since the outcome is sort of binary: one is either successful, or one fails and gets screwed-up in incomprehensible ways.
