If the control air pressure for an automatic combustion control system is lost during maneuvering, you should immediately __________.

🔍 Key Concepts

• Automatic combustion control systems on boilers and what the control air does • Difference between manual control of combustion and securing a boiler • Immediate actions required when a safety‑critical control medium (like control air) is lost

💭 Think About

• Ask yourself: If the automatic air-operated controls fail, what is the safest way to keep proper fuel/air ratio under your direct control during maneuvering? • Would you ever delay by working on compressors or receivers before stabilizing boiler operation and combustion? • Which option directly maintains or safely changes the firing condition, and which options are more about long-term air system management?

✅ Before You Answer

• Identify which choices directly affect boiler firing control (fuel and air) versus those that only address the air system hardware. • Consider what the vessel is doing during maneuvering and whether you can afford to completely secure the boilers at that moment. • Verify which action can be taken immediately and locally at the boiler front to maintain safe control of combustion.
