I'm hoping to get some help from other forum users about this topic. How long does it take for CO2 to become lethal? I've been doing some research on the topic, but I'm still not sure of the exact timeframe. Does anyone have any information or advice on this issue? Any help would be much appreciated.

CO2 is an odorless, colorless gas that is present in the atmosphere and is essential for life on Earth. However, when CO2 levels become too high, it can be dangerous and even lethal. The amount of time it takes for CO2 to become lethal depends on a variety of factors, including the concentration of the gas in the air, the individual's level of physical fitness, and the amount of time they are exposed to the gas.

Concentration of CO2

The concentration of CO2 in the air can vary greatly depending on the environment. Generally, CO2 concentrations in the atmosphere are around 400 parts per million (ppm). The Occupational Safety and Health Administration (OSHA) states that an 8-hour time-weighted average of 5,000 ppm or higher can be lethal. On the other hand, the National Institute for Occupational Safety and Health (NIOSH) states that a concentration of 4,000 ppm or higher can be lethal after just one hour of exposure.

Physical Fitness

The individual's level of physical fitness can also affect how long it takes for CO2 to become lethal. People who are physically fit have better cardiovascular and respiratory systems, which allow them to better tolerate higher levels of CO2. This means that it may take longer for CO2 to become lethal for people who are in good physical shape.

Time of Exposure

The amount of time an individual is exposed to CO2 will also affect how long it takes for the gas to become lethal. The longer a person is exposed to the gas, the more time they have to be affected by its toxicity. Therefore, it is important to limit the amount of time an individual is exposed to high levels of CO2.

In conclusion, the amount of time it takes for CO2 to become lethal depends on a variety of factors, including the concentration of the gas in the air, the individual's level of physical fitness, and the amount of time they are exposed to the gas. It is important to take steps to limit exposure to high levels of CO2 in order to avoid its potentially lethal effects.
