Which records must be kept in the boiler logbook for a First Class boiler operator?

• A. Start/stop times only
• B. Weather data
• C. Only fuel usage
• D. Start/stop times, safety device tests, pressures/temperatures, water level readings, maintenance, repairs, and abnormal conditions

Answer: (D)

The essential idea is that a boiler logbook for a First Class operator must document a comprehensive record of the boiler’s operation and safety checks, not just when it runs. This history shows that the boiler was operated within approved parameters, safety devices were tested and functioning, and any issues were noted and addressed. Start and stop times alone don’t prove that controls and safety systems worked, and they don’t capture how the boiler behaved during operation.

Recording safety device tests ensures everything that protects the boiler and the crew is reliable. Keeping track of operating pressures and temperatures, along with water level readings, provides a continuous check that the boiler is within safe limits and helps catch problems before they escalate. Documenting maintenance and repairs shows what work was done and when, which supports reliability and accountability. Noting abnormal conditions records any irregularities so they can be reviewed and corrected.

Weather data or fuel usage by itself doesn’t provide the full safety and operational picture. Therefore, the required records include start/stop times, safety device tests, pressures/temperatures, water level readings, maintenance and repairs, and abnormal conditions.
