The National Drowning Prevention Alliance and the U.S. Consumer Product Safety Commission advise pool owners to use multiple layers of protection to help prevent drowning in swimming pools and spas. These layers include a barrier or fence at least four feet tall with self-closing, self-latching gates; a pool or spa safety cover; and alarms or detection systems that alert adults of unauthorized access to the pool area.
All pools should be completely surrounded by a four-sided barrier. In residential settings, the house should not be considered one of those sides unless all doors and windows providing access to the pool area are equipped with self-closing, self-latching mechanisms and alarms that warn of entry.
Door and window locks and alarms should be installed high enough that a small child cannot reach them — even with the assistance of furniture. Where possible, doors should be self-closing and self-latching to reduce the chance of being left open.
Barriers can be constructed from a variety of materials, subject to local codes. Removable mesh fencing is among the most common options due to its durability, visibility, and flexibility in design.
An additional layer of protection can be provided by pool and spa safety covers. It is important to note that not all covers are safety covers. A true safety cover meets ASTM standards and is designed to support weight and prevent access to the water.
Alarms provide another important layer. Experts recommend installing alarms on all doors, windows, and points of entry leading to the pool area. Perimeter motion sensors can detect movement in the pool area and sound an alert, providing warning of unauthorized access before someone reaches the water.
There are also in-water alarm systems designed to detect disturbances or entry into the pool itself. Wearable alarm devices, such as wristband sensors, can trigger an alert when submerged; however, they are only effective if worn consistently and properly.
The National Drowning Prevention Alliance emphasizes that no single device or system can prevent drowning. Effective prevention relies on multiple layers working together.
In addition to physical barriers and alarms, critical layers of protection include constant, attentive, and undistracted supervision; teaching children water safety and swimming skills; learning safe rescue techniques; and knowing first aid and CPR, including rescue breaths.

And remember: no safety system replaces constant, capable, and undistracted adult supervision whenever a child is near water.
