Special care must be taken in checking the seat belts of certain types of passengers, especially the elderly, handicapped passengers, unaccompanied minors and others.
When there are infants among the passengers, cabin attendants should ensure that infants are seated so that there are sufficient oxygen masks for all the passengers in the row. For small children, it is recommended that a blanket be placed behind them so that the seat belt can hold them more securely.
