Is CO2 dangerous when used in poorly ventilated areas?

Carbon dioxide (CO2) can indeed be dangerous when used in poorly ventilated areas. In such environments, CO2 can accumulate to levels that lead to suffocation or health issues. The gas displaces oxygen in the air, which is necessary for human respiration. In poorly ventilated spaces, the supply of fresh air may not be sufficient to dilute the CO2 to safe levels.

When CO2 concentrations rise, individuals may experience symptoms like headaches, dizziness, shortness of breath, or even loss of consciousness in extreme cases. This is particularly critical in confined spaces where people might work or reside for extended periods without adequate airflow.

It's important to emphasize that the danger of CO2 is closely tied to both the concentration of the gas and the ventilation conditions of the space in which it is present. Thus, awareness of CO2 levels and ensuring proper ventilation is essential to maintaining safety in environments where CO2 is being used or generated.
