Dangers of CO2: What You Need to Know |

In a sealed environment, as oxygen levels drop from 21% to 17%, the CO2 level may rise to 4%. This level of CO2 can result in symptoms like dizziness, asphyxiation, confusion, fatigue, vertigo, headaches, tinnitus, and even seizures. Higher levels of CO2 can be life-threatening; and prolonged exposure to Carbon Dioxide (CO2) can even cause a ...
