Which of the following statements is true...

🔍 Key Concepts

• Identify the type of extinguisher shown (look at the separate gas pressure cartridge and hose/nozzle arrangement). • Recall how a cartridge‑operated dry chemical extinguisher is normally used on Class B (flammable liquid) fires. • Think about control of the discharge: what features on the nozzle/lever let you start and stop the agent flow?

💭 Think About

• From the illustration, what clues tell you whether this extinguisher’s agent flow can be controlled during use (on/off or continuous only)? • For a Class B fire, should you get very close to the fire at first, or start farther back and work in? How does that help you eliminate one option? • Does any standard portable extinguisher completely eliminate the risk of reflash on flammable liquids, or is reflash always a concern?

✅ Before You Answer

• Verify which choice matches the operating technique shown by the nozzle lever and hose (control of discharge). • Eliminate any option that claims there is no danger of reflash on a Class B fire – compare that with your basic fire‑fighting training. • Check whether the statement about using it with or without water is a general rule for this type, or if that sounds too absolute ("must never").
