This was found in Frankfurt airport, hanging every 100m or so in the hallway of the terminal. It’s a long narrow hallway. These signs are positioned such that if you are walking down the hall, the visual control indicates to go right. If you are walking across the hall to the other side, or standing parallel, the visual control is an ambiguous downward arrow. Is the message “exit here”? No, because it is hanging in the center of the hallway, the exits are on the other side.
It would be more helpful to make the emergency exit signs behind the Lufthansa counter larger and more prominent and have a visual with only left or right arrows to indicate that the nearest exits are through the boarding gate doors, rather than at the far ends of the hallway *cough* obviously *cough*.
