Each crew member must be provided with first aid in case of an accident or illness. The captain is responsible for organizing medical assistance. First aid is provided by a navigator who has attended a 90-hour course at the Seamen's Hospital, guided by this textbook on emergency medical care. The manual is addressed to students (cadets) of higher and secondary educational institutions of water transport, as well as members of ship crews who are required to provide first aid to victims in the absence of medical workers on board.
