Nitrogen is the inerting gas.

• A. False
• B. True
• C. Sometimes
• D. Unknown

Answer: (B)

Inerting gas means a gas used to displace or dilute oxygen in a space so combustion can’t start or spread. Nitrogen fits this role well: it’s non-flammable, chemically inert under normal conditions, and makes up most of the air we breathe. By introducing nitrogen, the oxygen level in an enclosed area drops, making it hard for a flame to ignite or continue burning. It’s a common, cost-effective choice for protecting vessels, electrical cabinets, and other confined spaces. While other inert gases (like argon) can be used in certain applications, nitrogen is the typical inerting gas, which is why this statement is true. (Keep in mind, high nitrogen levels can pose asphyxiation hazards, so proper safety design is essential.)
