Which term is listed as a type of investigation?

• A. Flooding
• B. Ventilation
• C. Assault
• D. Recovery

Answer: (A)

Understanding how a casualty is categorized for investigation helps the team apply the proper response. Flooding is listed as a type of investigation because water intrusion creates a distinct casualty scenario that requires a formal process to find the source, isolate the leak, pump out the water, and check watertight integrity. Ventilation is a system function used to control air quality and pressure, not an investigation category. Assault and recovery describe other activities or outcomes and aren’t how DC casualties are classified for investigation. Recognizing flooding as an investigation type ensures responders follow the correct steps to stop the water and preserve the ship’s buoyancy and integrity.
