🔍 Key Concepts

• Fire and explosion triangle (fuel, air, ignition source) • How unburned fuel can collect in a boiler furnace • Difference between conditions that cause stress on the boiler (like high steam demand) and conditions that actually trigger an explosion

💭 Think About

• Think about what THREE basic things are always needed for any explosion or fire, regardless of whether it is in a boiler, engine room, or galley. • Which option describes a condition that directly starts an explosion, rather than just affecting boiler operation? • Ask yourself: if unburned fuel and air are already present, what final condition is necessary for an explosion to actually happen at that moment?

✅ Before You Answer

• Confirm you can name all three sides of the fire/explosion triangle. • Eliminate any choices that describe operating conditions (like load or demand) rather than something that initiates combustion. • Check which option specifically provides the trigger that turns a combustible mixture into an explosion.
