Why is it important to monitor the oxygen levels during the sealing process?

Monitoring the oxygen levels during the sealing process is crucial primarily for safety reasons. During the sealing of mine areas, maintaining an appropriate level of oxygen is essential to prevent hazardous conditions that could endanger workers. A decrease in oxygen levels can signal that the environment is becoming unsafe for any work to be conducted, especially for the sealing teams who may need to enter those areas.

Additionally, proper monitoring contributes to ensuring that ventilation remains effective, which can directly influence gas concentrations, including flammable gases. Without sufficient oxygen, other gases that can be harmful or explosive may accumulate, posing significant risks. Therefore, while the choice selected touches on an important aspect, the primary purpose of monitoring oxygen levels is fundamentally for the safety of all workers involved in or affected by the sealing process. This safety ensures that the sealing process can be executed effectively without risk to personnel or the mine itself.
