🔍 Key Concepts

• Operation of portable extinguishers (PASS: Pull, Aim, Squeeze, Sweep) • How dry chemical works: interrupts the chemical reaction at the base of the flame • Controlling and covering the fuel surface rather than the flames

💭 Think About

• Where must the extinguishing agent actually contact to stop the fire: the flames, the smoke, or the fuel at the bottom? • If you stand back from the fire, which direction should you move the nozzle so you don’t push burning material into unburned areas? • Which technique gives you the widest, most even coverage across the burning edge of the fire with a limited amount of agent?

✅ Before You Answer

• Make sure the method directs the agent at the base of the fire, not above it • Check that the motion described allows side-to-side sweeping to cover the whole burning edge • Avoid any option that mainly relies on bouncing the stream off walls or focusing on small spots instead of the main burning edge
