Purging for fire prevention does indeed involve using an inert gas to effectively remove air or flammable gases from lines or equipment. The primary goal of this process is to reduce the risk of a fire or explosion by eliminating the presence of oxygen, which is necessary for combustion. By replacing the air with an inert gas, such as nitrogen, the likelihood of flammable mixtures forming is significantly mitigated.

This process is particularly essential in situations where equipment may hold residual flammable substances that could ignite if mixed with oxygen. Both operational safety and compliance with industry regulations necessitate such practices to prevent potential fire hazards in environments where flammable materials are handled or processed.

The other options suggest limitations or specific conditions under which purging might occur, which do not reflect the general application of purging as a proactive fire prevention measure.
