🔍 Key Concepts

• Fire triangle: fuel, heat, oxygen • Operation of portable dry chemical extinguishers • Proper aiming point when using fire extinguishers

💭 Think About

• Think about which part of the fire you must remove or cool to be most effective with a small extinguisher. • Consider where the dry chemical needs to land to interrupt the chemical reaction of burning, not just blow flames around. • Visualize how firefighters are trained to sweep an extinguisher—what are they told to aim at?

✅ Before You Answer

• Identify which choice deals directly with the source of combustion (where the fuel is burning). • Eliminate any option that mainly affects only the visible flames and not the burning material. • Ask: With limited agent in a portable extinguisher, where must I aim to stop the fire from continuing to burn?
