When operating the air supply system in a covered lifeboat the __________.

🔍 Key Concepts

• Purpose of the air supply system in a covered lifeboat (what problem is it designed to solve?) • How smoke, gas, or fumes can enter a covered lifeboat during a fire or oil spill • Which valves or openings must be open vs. closed for fresh air to actually circulate safely

💭 Think About

• Think about when you would use the air supply system — what type of emergency and what are you trying to keep out of the boat? • Which items in the choices, if closed, would stop the system from working as intended rather than help it? • Which parts of the lifeboat must be sealed so the air system can protect people inside from outside contamination?

✅ Before You Answer

• Identify which choice best supports keeping contaminated outside air and fumes out of the boat while still allowing the air system to function • Eliminate any option that would shut off the air system’s supply (air or engine) when you actually want it to work • Confirm that your chosen action is consistent with using the air system, not preparing to abandon or disable it
