🔍 Key Concepts

• 46 CFR inspection and reporting requirements for pressure-containing parts on boilers • The safety function and construction of each listed boiler component (gasket, plug, gage glass, water column) • Which components are considered critical safety devices whose renewal affects the boiler’s certification or inspection record

💭 Think About

• Ask yourself which of these components, if it failed, could directly lead to a dangerous overpressure or uncontrolled release of steam/water from the boiler. • Think about which items are considered routine maintenance consumables versus which are specially designed safety devices that surveyors pay close attention to. • Consider which part’s replacement would most likely be documented in the vessel’s official boiler or machinery records for regulatory review.

✅ Before You Answer

• Identify which listed parts are pressure-retaining safety devices rather than simple sealing or indication items. • Recall from 46 CFR which boiler parts are specifically mentioned as requiring notification or written report to the OCMI when renewed or altered. • Separate normal maintenance items (like gaskets or easily replaced indicators) from items that directly affect boiler safety and certification.
