Narrative:

At the gate at ZZZ, united states. While the passenger were boarding, a man apparently walked in our left engine propeller blade. He was uninjured. I did not witness the incident. The flight attendant mentioned it to me and also that the passenger did not speak of the incident. There apparently weren't any ramp agents watching the boarding process at that particular time. They had been earlier. I believe that they were in a rush to load bags in the cargo area and left only momentarily. Just something for everyone to think about. Slow down and think safety first. Some orange cones might help too.
