What level of CO2 is toxic to humans

[CuriousCat]

"Hi everyone, I'm looking for some help with a question I have about the toxicity of CO2 levels for humans. Does anyone have any information on what level of CO2 is considered toxic and why? Any information or personal experiences you can share about this topic would be greatly appreciated.

CO2 Toxicity Levels

The level of Carbon Dioxide (CO2) that is toxic to humans is highly dependent on the duration of exposure and the concentration of the gas. The short-term exposure limit (STEL) for CO2 is currently set at 30,000 ppm by the American Conference of Governmental Industrial Hygienists (ACGIH). This level should not be exceeded for more than 15 minutes in a given 8-hour period.

Long-Term Exposure to CO2

Long-term exposure to lower concentrations of CO2 may also have negative health effects. According to the U.S. Environmental Protection Agency (EPA), prolonged exposure to levels of 5000 ppm or higher can cause health issues such as headaches, dizziness, and fatigue. Additionally, levels of 10,000 ppm or higher can cause respiratory and cardiovascular issues.

Exposure to High Concentrations of CO2

Exposure to extremely high concentrations of CO2 can be fatal. According to the National Institute for Occupational Safety and Health (NIOSH), concentrations of 40,000 ppm or more can cause asphyxiation within minutes. It is important to note that concentrations of CO2 above 30,000 ppm are generally only found in occupational settings such as research laboratories, greenhouses, and commercial CO2 storage tanks.

Exposure to high levels of CO2 can be toxic to humans. Generally, levels of CO2 considered safe for humans are between 350-1,000 parts per million (ppm). Anything above 1,000 ppm can lead to headaches, dizziness, difficulty breathing, and even death in extreme cases. Long-term exposure to high levels of CO2 can also increase the risk of developing cardiovascular and respiratory illnesses. Therefore, it is important to keep indoor air levels of CO2 at or below 1,000 ppm to ensure the safety of people.

The level of CO2 at which humans become toxic is generally considered to be around 10,000 parts per million. However, this can vary depending on factors such as the length of exposure and activity level of the individual. CO2 poisoning typically occurs when CO2 levels exceed 30,000 parts per million, and can lead to difficulty breathing, headaches, dizziness, and even loss of consciousness. Prolonged exposure to high levels of CO2 can also lead to long-term effects such as neurological damage, heart damage, and death.

Question: What level of CO2 is toxic to humans?

Answer: The toxicity of CO2 to humans depends on the concentration and duration of exposure. Generally, a concentration of 10,000 ppm or higher is considered to be toxic to humans, and can cause symptoms such as shortness of breath, dizziness, headaches, and confusion. Long-term exposure to these levels of CO2 can lead to more serious health problems, including death. Therefore, it is important to ensure that the level of CO2 in any environment is kept below the 10,000 ppm threshold.

What level of CO2 is toxic to humans?

The level of CO2 that is toxic to humans is generally considered to be greater than 5000 ppm. Concentrations above this level can cause various health problems, such as headaches, dizziness, and difficulty breathing. It is important to note that the effects of long-term exposure to high levels of CO2 are still being studied.
