The aim of the present study was to identify the rescuer characteristics. Qualitative content analysis was utilized to analyze drowning incident videos (n = 41) and semi-structured interviews of those involved in drowning incidents (n = 34). The rescuers were mainly but not exclusively males between 20–30 years old, physically strong, fit, with good vision, and swimming ability; they tended to hold an updated lifeguard qualification and had previous work experience as a lifeguard; they knew the dangers of the aquatic area. Most of them worked as a member of a lifeguard team, cooperated with other emergency services, were able to visually detect and recognize a drowning casualty and reacted fast despite the lack of response by bystanders.
