Data collected on nine nuclear-powered ballistic missile submarines indicate an average CO2 concentration of 3,500 ppm with a range of 0-10,600 ppm, and data collected on 10 nuclear-powered attack submarines indicate an average CO2 concentration of 4,100 ppm with a range of 300-11,300 ppm (Hagar 2003).

CO2 is a simple asphyxiant and lethal asphyxiations have been reported at concentrations as low as 110,000 ppm (Hamilton and Hardy 1974). Loss of consciousness can occur within a minute of exposure at 300,000 ppm and within 5-10 minutes (min) of exposure at 100,000 ppm (HSDB 2004). The effects of concentrations of CO2 between 7,000 and 300,000 ppm in humans and animals are discussed below and include
