Maximum of 9 ppm of CO for 8-hour exposure (not to be exceeded more than once per year). What is carbon monoxide? Carbon monoxide (CO) is a colorless, odorless deadly gas. Because you can't see, taste, or smell it, carbon monoxide can kill you before you Reading Suggests; 10 ppm and over: recent exposure to a high level of carbon monoxide. This is a typical reading for smokers: 5–9 ppm: recent exposure to a moderate level of carbon monoxide. 200 PPM: Dizziness, naseau, fagitue, headache after 2-3 hours of exposure.

Normal Even low carbon monoxide levels over long periods can have an impact on brain chemistry. While exact short term and long term CO levels recommended by ASHRAE, OSHA, NIOSH and other organizations differ, the consensus is that 9 ppm (parts-per-million) is the maximum indoor safe carbon monoxide level over 8 hours.
