What atmospheric component is ventilation designed to remove along with excessive heat and stale air?

Ventilation systems are primarily designed to improve air quality and comfort by removing excessive heat, stale air, and potential contaminants from indoor environments. One of the critical atmospheric components that ventilation helps to remove is harmful gases, including explosive or toxic gases. This is crucial in various settings, such as industrial environments, laboratories, and areas where combustion occurs, where the accumulation of such gases can pose a significant risk to health and safety.

Effective ventilation serves to dilute and disperse these hazardous gases, preventing dangerous concentrations that could lead to explosions or toxicity. While other options like humidity, dust particles, and carbon monoxide are also important considerations in ventilation, the removal of explosive or toxic gases is often prioritized to safeguard against immediate health hazards.
