In the context of fire hazards, why is it important to monitor the levels of inert gas within a purge system?

Monitoring the levels of inert gas within a purge system is crucial for maintaining a safe environment. Inert gases, such as nitrogen or argon, are used to displace oxygen and other reactive gases, effectively reducing the risk of combustion or explosion in areas where flammable materials or processes are present. By ensuring that the concentration of inert gas is at appropriate levels, the likelihood of unintended ignition or fire hazards occurring is minimized. This is especially important in industrial processes that handle volatile substances, as an oxygen-rich atmosphere can lead to increased fire risks. Therefore, regularly checking and maintaining the right levels of inert gas provides a protective barrier that enhances overall safety in the facility.
