🔍 Key Concepts

• Cargo and ballast tank monitoring requirements in 46 CFR for tank vessels • Purpose of a high-level alarm versus an overfill alarm • Requirements for alarm signals to get the operator’s attention in a control room or cargo space

💭 Think About

• Think about what feature is most important so that a watchstander immediately recognizes a high-level condition, even if they are not looking directly at a gauge. • Consider whether a high-level alarm is intended to work by itself, or whether it must always act together with other alarms or at a fixed percentage level. • Ask yourself how regulations usually ensure that a critical alarm cannot be overlooked in a noisy or busy machinery or cargo area.

✅ Before You Answer

• Check which choice matches a required characteristic of the high-level alarm itself, not a specific percentage or setting. • Verify whether regulations distinguish between high-level and overfill alarms as separate functions. • Confirm that regulatory alarm requirements usually include a sense (sound/light) requirement so operators can’t miss them.
