What is installed to designate a break in the pool where water depth is five feet or greater?

The correct approach to indicating a break in the pool where the water depth reaches five feet or greater involves implementing both a safety line and a slope break marking on the pool floor. This dual measure serves to enhance swimmer safety by providing visible cues about changing depths.

A safety line is typically a buoyed line that floats on the surface of the water, clearly marking the transition from shallower to deeper areas. This serves as a preventative measure, informing swimmers that they are approaching a depth that may require more confidence or skill.

In addition, slope break markings on the pool floor are essential for visually guiding swimmers and helping them assess the depth. These markings can be in the form of contrasting colors or patterns that indicate where the depth changes, making it easier for swimmers to notice and adjust their activities accordingly.

Together, these two measures create a clear visual indication of depth changes, ensuring a safer swimming environment for all pool users.
