Blank supervision means that you keep children in your view at all times when they are in or near the water

to ensure their safety. This involves never leaving them unsupervised and always being vigilant and aware of their activities in the water. It is important to also be able to intervene quickly if necessary to prevent any accidents or incidents from occurring. Remember, drowning can happen quickly and silently, so it is crucial to always keep a close eye on children when they are in or near water.
