What is the primary reason for monitoring the oxygen levels in a tank?

Monitoring oxygen levels in a tank is essential primarily for safety reasons, particularly to prevent combustion. Many flammable materials are transported in tanks, and the presence of oxygen combined with these substances can create a dangerous environment where combustion or explosions can occur. Therefore, maintaining oxygen levels below certain thresholds is crucial to mitigate the risk of fire and ensure the safety of personnel and the facility.

This focus on safety is paramount in various settings where tankers are filled or discharged, especially when handling combustible materials. Keeping an accurate check on oxygen concentrations helps ensure that the atmosphere within the tank remains inert or adequately controlled, thereby minimizing the likelihood of ignition.

While other considerations like cargo integrity, optimizing loading operations, and reducing emissions are important in their own right, they do not directly address the immediate safety concerns related to combustion risks in the same way that monitoring oxygen levels does.
