Final answer:
Anything that would provide a climbing surface for children in or on a pool barrier is a drowning hazard. Examples of climbing surfaces on pool barriers include ladders, handholds, or any other structure that can be used by children to climb over the barrier. It is important to ensure that pool barriers are free from any climbing surfaces to prevent accidents and keep children safe.
Step-by-step explanation:

When there are climbing surfaces on a pool barrier, it becomes easier for children to access the pool and increases the risk of drowning. Examples of climbing surfaces on pool barriers include ladders, handholds, or any other structure that can be used by children to climb over the barrier. It is important to ensure that pool barriers are free from any climbing surfaces to prevent accidents and keep children safe.
