🔍 Key Concepts

• 46 CFR requirements for boiler safety valves on inspected vessels • Purpose of drain lines and why additional shutoff valves can be dangerous • Who is authorized to set and seal safety valves and what documentation is normally required

💭 Think About

• Look at each option and ask: is this a specific Coast Guard regulatory requirement, or does it sound like normal shipboard practice or opinion? • Think about why a safety valve exists. Which of these choices, if applied incorrectly, could defeat or interfere with the safety function? • Consider whether the location and operation of the lifting device is strictly limited to the fire room by regulation, or whether the regulation is worded more generally.

✅ Before You Answer

• Check whether 46 CFR explicitly prohibits valves on the safety-valve drain lines or just discourages them in practice. • Verify if 46 CFR says safety valves must be set and sealed by a Coast Guard–authorized facility or inspector, rather than by the ship’s Chief Engineer. • Confirm the exact wording for the lifting device requirement: does the rule specify it must be operable only from the fire room, or simply that it must have a suitable lifting device for testing.
