This should worry you because it's a highly toxic poisonous gas.
Carbon monoxide is heavier than air so it falls down, make sure CO doesn't leak through the floor, or anywhere for that matter.
Also, if you can, don't do it when you live so close to other people, maybe find a abandoned house, building, whatever, somewhere you can seal things of and bring in the glowing charcoal, and start producing copious amount of carbon monoxide.
