What is the required amount of sodium nitrite used for a sodium nitrite wet lay-up?

• A. 5 pounds per 1,000 gallons
• B. 10 pounds per 1,000 gallons
• C. 15 pounds per 1,000 gallons
• D. 20 pounds per 1,000 gallons

Answer: (B)

The correct amount of sodium nitrite used for a sodium nitrite wet lay-up is 10 pounds per 1,000 gallons. This concentration is important because sodium nitrite serves as a corrosion inhibitor in the preservation of water-filled systems, particularly in marine and industrial applications. The specified dosage effectively protects metal surfaces within tanks and piping from corrosion during periods of inactivity or maintenance. Using the correct amount ensures adequate coverage and effectiveness of the corrosion protection without introducing excess chemicals that could lead to other complications. A dosage lower than 10 pounds may not provide sufficient protection, while a higher concentration could be wasteful and may even lead to other chemical imbalances in the water system. Thus, 10 pounds per 1,000 gallons strikes the right balance for maintaining the integrity of the system.
