Question 1 of 27070

In accordance with Coast Guard Regulations (46 CFR), which of the following power sources would be acceptable for the carbon dioxide warning alarm?

🔍 Key Concepts

• 46 CFR requirements for fixed carbon dioxide (CO₂) fire extinguishing systems • Purpose of the CO₂ WARNING ALARM and what happens to power during a fire/emergency • Difference between ship’s service power and emergency power sources

💭 Think About

• If a CO₂ system is discharging during a fire, what might happen to the normal ship’s power supply? How should the alarm still be able to function? • Which option best ensures the alarm will sound even if the main power fails or is secured as part of the fire response? • Does the regulation favor a power source that is independent, backed up, or connected to emergency systems?

✅ Before You Answer

• Verify which answer choice clearly references the emergency power system or emergency batteries/generator rather than normal ship service power. • Check that the power source described is reliable during a casualty and not likely to be lost when CO₂ is released or main power is shut down. • Confirm in 46 CFR Subchapter I (fire protection systems) how the CO₂ warning alarm is required to be powered, especially regarding emergency power availability.
