Why is ventilation crucial when working in confined spaces?

Ventilation plays a vital role when working in confined spaces primarily because it helps remove hazardous gases and maintain safe conditions. In enclosed areas where air circulation is limited, there is often a buildup of harmful substances, including toxic gases, vapors, or lack of oxygen. Proper ventilation allows fresh air to enter the space, diluting and dispersing these hazards effectively. This process helps to ensure that the atmosphere remains within safe limits for workers, reducing the risk of asphyxiation, poisoning, or flammable environments.

While ventilation can affect other factors in a confined space, such as temperature and noise, the primary goal and necessity are to create a safe and breathable environment. Therefore, maintaining adequate ventilation is a critical safety measure that cannot be overlooked.
