What does an oxygen indicator detect in a confined space?

An oxygen indicator serves the critical function of monitoring the oxygen levels within a confined space, specifically detecting oxygen deficiency. This is crucial for ensuring the safety of individuals working in environments where there may be a risk of asphyxiation due to low oxygen concentrations. By measuring the percentage of oxygen present, the indicator can alert workers if levels drop below safe thresholds, which is vital for preventing hazardous conditions that could lead to serious health risks or accidents.

Understanding the importance of oxygen deficiency detection is key in many industrial applications, especially when working in enclosed areas where ventilation might be limited. This highlights the essential role oxygen indicators play in occupational safety and compliance with environmental health standards.
