Drowning occurs more commonly when children get access to the pool during a short lapse in adult supervision. To reduce the risk of drowning, pool owners should adopt several layers of protection, including physical barriers, such as a fence completely surrounding the pool with self-closing, self-latching gates to prevent unsupervised access by young children. If the house forms a side of the barrier, use alarms on doors leading to the pool area and/or a power safety cover over the pool.
