Depth markings in pools must be visible from where?

Depth markings in pools must be visible from the water to ensure the safety of all swimmers. Visibility from the water allows individuals swimming in the pool to quickly ascertain the depth of various sections, which is essential for making safe decisions about diving, jumping, or swimming. This visibility helps to prevent accidents and injuries that can occur when swimmers are unaware of the depth, especially in areas with sudden changes.

While it is also beneficial for markings to be visible from the pool deck or other areas, the primary concern is ensuring that those in the water can easily see and understand the depth of the pool at all times. This requirement is a crucial safety feature outlined in swimming pool regulations, promoting a safe environment for all users.
