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

• A. In place, compacted packaging present
• B. In place, gauge in green sector
• C. In place, tamper seal attached
• D. In place, securely stowed with red disc showing

Answer: (D)

The needed check focuses on two things: the extinguisher must be in its designated place and secured, and there must be a clear visual indication that the unit hasn’t been tampered with or discharged. The water extinguisher uses a red disc as a tamper/indicator disc; when this disc is showing, it confirms the seal is intact and the unit is ready for use. So “in place, securely stowed with red disc showing” is the correct description because it covers both secure storage and a visible indicator of serviceability. The other options describe conditions that would not reliably confirm readiness: packaging or loose placement would imply the extinguisher isn’t properly stowed, and a gauge or tamper seal alone doesn’t provide the immediate, universally visible confirmation that the red disc offers.
