What is the purpose of a nitrogen blanket in lay-up procedures?

• A. To maintain a stable temperature
• B. To prevent corrosion
• C. To enhance fuel efficiency
• D. To support the structural integrity

Answer: (B)

The purpose of a nitrogen blanket in lay-up procedures is to prevent corrosion. When equipment or systems are laid up for an extended period, moisture and oxygen can lead to rust and deterioration of metal components. Nitrogen, being an inert gas, displaces oxygen and moisture, thus creating a barrier that minimizes the chances of corrosive reactions occurring. By filling the space with nitrogen, it protects the internal surfaces from oxidation and helps preserve the integrity of the machinery or system until it is ready to be used again. This practice is particularly important in environments where metal components are susceptible to corrosion, such as in storage or during long-term inactivity.
