Why would a flight attendant use an iodine wipe?

• A. For wounds, to prevent infections
• B. To clean the cabin surfaces
• C. To sterilize water
• D. To sanitize hands

Answer: (C)

Iodine acts as a disinfectant that can render questionable drinking water safe in emergencies. In flight scenarios where the source or safety of water may be uncertain, using an iodine-based treatment helps kill pathogens so passengers can drink without as much risk of illness. While iodine products can also be used for skin antisepsis or surface cleaning, in this context the emphasis is on making water safe for consumption when reliable supplies aren’t available.
