🔍 Key Concepts

• 46 CFR Subchapter F – Marine engineering regulations for machinery and boilers • Requirements for notifying the OCMI (Officer in Charge, Marine Inspection) about machinery/pressure vessel work • Fuel flash point and sampling requirements for tankships burning oil in boilers

💭 Think About

• Which of the options clearly matches a specific, detailed requirement you’ve seen in 46 CFR, rather than sounding like a general good practice? • Do all three statements belong to the same regulatory theme and section, or do they appear to come from different topics within 46 CFR? • Ask yourself: if one of these items were not required anywhere in 46 CFR, which would it most likely be, and why?

✅ Before You Answer

• Check 46 CFR sections on repairs to boilers and pressure vessels and see when OCMI notification is required • Check 46 CFR sections on fuel oil burning equipment for tank vessels for flash point requirements • Look for any explicit requirement in 46 CFR that a sealed sample of EACH load of fuel be kept until that fuel is exhausted — confirm if this wording actually appears
