🔍 Key Concepts

• Look closely at the numbered parts on the extinguisher head in the illustration and think about which one is the safety pin and which part is the operating lever. • Recall the basic extinguisher sequence: safety device first, then the control that actually releases the agent. • Decide whether this particular design has a separate "valve" in addition to the squeeze/release lever, or if the lever itself acts as the valve.

💭 Think About

• Which step must always be done before any valve or lever can move freely, to prevent accidental discharge? • On the style of head shown, once the pin is removed, what physical action on which part will actually let CO₂ flow into the hose and horn? • Do you see any other handwheel or valve body that would need to be opened separately from the operating lever, or is there only one control for discharge?

✅ Before You Answer

• Identify which choice starts with removing the safety device before anything else. • Eliminate any option that requires you to move a control that is still locked by the pin. • Confirm whether the illustration shows a separate valve control in addition to the release lever; if it does not, be cautious about answers that treat them as two different things.
