Why? Are you planning on doing something to hurt yourself or others? Please, call 911 immediately.
It depends on the amount/time of exposure. If you feel that you or your family have CO poisoning, you need to be evaluated.
High concentrations can kill in 5 minutes. Lower levels can take up to 8 hours.
Hello, It depends on the concentration. For example, at 100% concentration asphyxiation occurs in about 5 minutes. At low concentration it could take hours.
It depends on the degree of exposure. In an enclosed space, it can kill rather quickly, like less than an hour. If the space is not enclosed, it can take days to make you ill.
