What should be done to ensure safety in designated open swimming areas?

Marking off boundaries clearly is essential for safety in designated open swimming areas because it helps to define the limits within which swimmers can safely operate. Clear boundaries establish a visual cue for swimmers about where they can swim without encountering unsafe conditions, such as deep water or areas with strong currents. This practice aids in managing the flow of swimmers and can reduce the risk of accidents or distress.

Additionally, well-marked boundaries can assist lifeguards in effectively monitoring the designated area, making it easier to identify when swimmers are in trouble or have strayed outside the safe zones. By providing a defined space, swimmers can feel more at ease and less likely to drift into potentially hazardous areas, contributing to a safer swimming environment.
