According to 46 CFR, Subchapter I (Cargo and Miscellaneous Vessels), it is required that storage batteries to be tested for a specified period of time to demonstrate their ability to properly supply the required emergency load. What statement is true concerning the time interval between load tests?
• 46 CFR Subchapter I requirements for emergency power on cargo and miscellaneous vessels • The purpose of load testing storage batteries that supply emergency systems • Difference between inspection/maintenance checks and formal load tests
• Think about how often it is reasonable and practical to remove an emergency battery system from normal service for a full load test on a commercial vessel. • Compare the typical intervals you see in the CFR for other periodic tests and inspections—are they usually weekly, monthly, semiannual, or annual? • Ask yourself: if the interval is too long, safety suffers; if it is too short, it interferes with operations. Which option looks like a balanced regulatory compromise?
• Look up the exact wording in 46 CFR Subchapter I under emergency power/storage batteries and note the specified test interval. • Verify that the requirement is for a load test (not just a visual check or routine inspection). • Confirm that the language says "at least once each ___ that the vessel is navigated," and match that blank to one of the answer choices.
