MAKING YOUR TENT AIRTIGHT
#tent #insulation #co #monoxide
Here's a shot of a cheap tent that I always keep in the car (this is a decathlon tent, working on the white inner part), with one of the spray cans, and a closeup of a sprayed area.You want to lay on several coats, every one thin - take your time, let it dry... till the surface stays shiny when dry...
Use whatever spray paint you have, or those you can get cheapest, but the last coat should be shiny not matte... the entire coat should be thick, don't save on the spray cans... the tent will become noticeably stiffer.
You could instead use a large foil, which would be a second way (you would have to place the foil between inner and outer tent, and use duct tape additionally, to seal off holes, which can be ennervating). The spray way is better insofar as you can simply build up your tent at the campsite and concentrate on the CO biz.. Matter of taste. Also, I didn't have a fitting foil available today ;)
Tents are lofty and the fabric they are made from may be polyester or cotton, in any case these are thin interwoven threads, a lot like a grid, a mesh where air or gas has no problem passing though the gaps between the single threads.
It will keep wind and rain from passing, but not a slow gas... your CO will evaporate into the great outdoors within ten to twenty minutes if you don't prepare this well. But if you do, the sticky, gluey paint will fill the gaps between the threads and your tent can be almost as airtight as a space shuttle.
Recapitulation:
You want to create as high a CO concentration as possible, but you want to fire as little charcoal or use as little acid as possible... whatever you do will be a compromise... if you reach 10000ppm, you'll be out of here in a few seconds, but what if you only reach 4000ppm ?
Well, if your tent (or room, or car) is air tight, you will doze off peacefully and be dead in half an hour.
If not, you will quite possibly wake up again, maybe a day or two later, and maybe in hospital.
So...this is what you can do.
