What is the main advantage of using inert gases in the maintenance of equipment?

The main advantage of using inert gases in the maintenance of equipment is their role in flammability prevention. Inert gases, such as nitrogen or argon, do not support combustion and can displace oxygen in an environment. By creating a protective atmosphere, the risk of fire or explosion is significantly reduced, particularly in areas where flammable materials or vapors may be present. This is particularly important in industries dealing with volatile substances, as maintaining a non-flammable environment is vital for safety.

Using inert gases is a well-established practice in various applications, such as purging tanks, pipelines, and other equipment before maintenance work begins. This precaution helps ensure a safer working environment by minimizing the likelihood of ignition due to sparks or heat generated during maintenance activities.
