Coast Guard Regulations (46 CFR Part 58) require a method for the relieving pressure of an over pressurized refrigeration system. Which of the following statements complies with these Regulations?

Correct Answer: Option B — A rupture disk may be fitted in series with the relief valve.

Per 46 CFR Part 58, a rupture disk may be installed in series on the inlet side of a pressure relief valve. This protects the relief valve from corrosive vapors and prevents minor seat leakage while ensuring emergency relief capabilities.
