Why is it important to know if an atmosphere is oxygen deficient?

Understanding whether an atmosphere is oxygen deficient is crucial primarily for health and safety. When the concentration of oxygen in the air drops below safe levels, it can lead to serious health implications, including asphyxiation or impaired cognitive function. Workers in environments such as wastewater treatment plants must be educated and aware of oxygen levels to protect themselves from potentially life-threatening situations.

Recognizing the presence of an oxygen-deficient atmosphere helps operators implement necessary safety measures, like using personal protective equipment and ensuring adequate ventilation. Monitoring oxygen levels is a key part of maintaining a safe work environment, making health and safety the paramount concern in such scenarios.
