🔍 Key Concepts

• 46 CFR Part 58 – Engineering Systems (look for the section on refrigeration and pressure vessels) • Pressure relief protection – why relief valves are used on closed or isolated pressure vessels • Maximum allowable working pressure (MAWP) – and how safety valve settings are normally related to MAWP

💭 Think About

• Which answer choices talk about pressure relief rather than inspections, storage, or handling? • Think about standard practice for safety valves on pressure vessels: are they usually set at, above, or below the maximum allowable working pressure? • If a vessel can be isolated and heated (for example by ambient temperature), what must prevent the pressure from rising to a dangerous level?

✅ Before You Answer

• Verify in 46 CFR Part 58, Subpart 58.20 (Refrigeration Systems) which specific wording is used for relief valve settings on refrigerant pressure vessels. • Check whether the regulation mentions a percentage of maximum allowable working pressure (MAWP) for the relief setting. • Confirm that the required protection is an automatic pressure‑relieving device, not just periodic testing or storage requirements.

Question 1 of 20

According to 46 CFR Part 58, each pressure vessel, which is capable of isolation, containing a refrigerant, must be protected by what means?

subject to annual hydrostatic tests to be performed in the presence of a marine inspector

protected by a relief valve set to relieve at a pressure not exceeding 110 percent of the maximum allowable working pressure of the vessel

stored in an upright position in addition to being secured so as to prevent accidental release of the refrigerant within a confined space

protected by a relief valve set to relieve at a pressure not exceeding the maximum allowable working pressure of the vessel
