In the context of confined spaces, what can a lack of oxygen lead to?

A lack of oxygen in confined spaces can lead to asphyxiation because the human body relies on a certain level of oxygen in the air to function properly. When the oxygen concentration falls below safe levels, individuals can experience vital physiological effects, such as dizziness, confusion, loss of consciousness, and ultimately, death if the condition is prolonged.

In confined spaces, where air circulation may be limited, oxygen can be consumed by combustion or other processes, or it may be displaced by gases such as carbon dioxide. As a result, workers in such environments face significant health risks, making it crucial to ensure proper ventilation or the use of breathing apparatus when oxygen levels are not maintained. Understanding the dangers of asphyxiation reinforces the importance of safety protocols in confined spaces and highlights the necessity of monitoring atmospheric conditions before and during work activities.
