Fences or walls at least four feet high completely around the pool, free of articles that a child could use to climb over fence, such as lawn chairs or BBQ grills
Gates that are self-closing and self-latching, that open outward with latches out of reach of children
Installing alarms on doors leading to the pool area, or alarms on the pool
Using a cover for the pool when it is not in use
Making sure drain covers are properly fitted and are paired or have vacuum suction releases to prevent being trapped under water
Keep rescue equipment close by. This should include a sturdy, lightweight pole at least 10-12 feet long, a ring buoy with line, and a portable or mobile telephone. Steps and ladders for above-ground pools should be secured or removed when the pool is not in use.
Get inspected. Have your pool inspected for electrical hazards, and upgrade all systems according to local codes and the National Electrical Code. Also, any diving board, rock, platform, or slide should be inspected before they are used.
Respect electricity. Use battery-operated appliances instead of cord-connected appliances in and around the pool.
Prepare for emergency. Know where all electrical switches and circuit breakers for pool equipment and lights are located and how to turn them off in an emergency. Learn how to perform CPR. Keep a first aid kit close by.
