Just failed my CO attempt

[brokennsad]

Don't have to keep it there that long. Breathing through a tube while i wait for the CO to build up until the sensor reads 10,000. After that i just take the tube out my mouth and if my research is correct i should be passed out in a couple breaths and dead within a few minutes.
Only problem is the paradox of door sealing, and getting the charcoal right so it actually reaches 10,000
