Which description matches the correct pre-flight check for the Hafex extinguisher?

• A. In place, red disc showing
• B. In place, gauge is in the green sector
• C. In place, gauge is in the green sector, safety pin and seal are intact.
• D. Not in place

Answer: (C)

The key idea is confirming the extinguisher is truly ready to use. For the Hafex extinguisher, a proper pre-flight check means three things are correct: the unit is in place and secured, the pressure gauge shows the green sector (indicating adequate charge), and the safety pin with its seal is intact. Together, these confirm that the extinguisher is not discharged, has not been tampered with, and is accessible in an emergency. If any of these are missing or incorrect, the extinguisher isn’t considered ready: not in place means it could be loose or missing; the gauge not in green means the pressure may be insufficient or dangerous to rely on; and a broken or missing pin/seal suggests prior tampering or use. The description that includes all three conditions—in place, gauge in green, and pin/seal intact—is the correct match.
