Use layers of protection around your pool. This means you have several things in place to keep children from getting to the water.
Use these LAYERS OF PROTECTION for your pool area:
Fencing and gates-Mesh fencing should be at least four feet high and have a self-closing, self-latching gate. All panels should remain in place when the pool is not in use. Fencing should meet the ASTM F 1908 standard
Door and gate alarms-Many devices are available that attach to pool/spa access doors and gates that will sound a loud alarm when opened and closed. Placing alarms on sliding doors, windows and all exit doors will alert you to children leaving the house. Alarms should meet the Underwriters Laboratories standard UL 2017 for residential water hazard alarm equipment.
Perimeter and motion alarms-Infrared systems sound an alarm when the beam is crossed and can be installed around the perimeter of a pool or spa. Water motion alarms are placed near or in the water and sound an alarm when the water is disturbed.
Latch and locksFence-Gates should have latches that automatically close and latch securely. Windows and doors that open to the pool or spa area should all be equipped with self-latching devices.
Safety Covers-Pool covers are available that completely cover the pool or spa, blocking access to water. Insist on a cover that has a label stating that it meets the ASTM F1346 Standard for pool and spa covers.
