🔍 Key Concepts

• Boiler furnace safety before ignition and what can be present in the furnace from previous operations • Difference between ventilating/clearing the furnace vs cooling it • What conditions are dangerous if fuel is introduced without proper preparation of the furnace

💭 Think About

• Ask yourself: Right before automatic ignition, what is the single most important safety concern inside the furnace? • Think about what could be left in the furnace from a failed start or shutdown and what might happen when a new fuel spray and spark are introduced. • Which option directly addresses preventing a furnace explosion, not just improving combustion or cooling metal surfaces?

✅ Before You Answer

• Verify which choice deals with removing dangerous mixtures already in the furnace, not helping the next flame burn better. • Eliminate any choices that focus mainly on metal temperature rather than gas/vapor safety. • Check which answer matches the idea of using air flow over a timed period before ignition and why that is required by boiler safety practices.
