🔍 Key Concepts

• 46 CFR Part 61 – Periodic Tests and Inspections of Machinery • Differences in test intervals for fire-tube vs. water-tube boilers • Specific wording in the regulation about safety valve tests witnessed by a marine inspector

💭 Think About

• Locate the exact section in 46 CFR Part 61 that covers boiler safety valves and note any distinctions based on boiler type and pressure range • Compare the required interval for safety valve tests on fire‑tube boilers under 150 psig with intervals for other boiler types or higher pressures • Ask yourself whether the regulation uses a simple whole‑year interval or a less common fraction, and why that might be

✅ Before You Answer

• Verify you are in 46 CFR 61.05 (or related boiler test/inspection sections), not another part of the CFR • Confirm the text specifically refers to fire‑tube boilers operating at less than 150 psig and not all boilers in general • Double‑check the stated interval in years for tests witnessed by a marine inspector, and that you are not confusing it with the interval for other boiler inspections or internal examinations
