Purging use of an inert gas to sweep.

• A. Not sure
• B. Sometimes
• C. False
• D. True

Answer: (D)

Purging with an inert gas to sweep a space is a standard safety technique because it displaces air and flammable vapors with a nonreactive gas. By flowing nitrogen (or another inert gas) through the area, contaminants are flushed out and replaced by the inert atmosphere, reducing the chance that flammable mixtures form and that ignition sources can ignite them. This approach is used during maintenance, commissioning, leak testing, or hot-work preparation to help prevent fires or explosions. Oxygen and vapor levels are typically monitored during the purge to ensure safety. Therefore, this statement is true.
