The 20 most important pool safety measures are:

1. Be sure all pool users know how to swim. Teach your children as early as possible.
2. Never leave small children unsupervised in or around the pool -- even for a minute.
3. Do not allow pool use without your knowledge.
4. Keep small children and animals out by installing a yard fence.
5. Don't place lawn furniture near the fence; children may climb over.
6. Consider alarms, locks and safety covers for fence and pool.
7. Keep small children away from pool filters. The suction may injure them or prevent them from reaching the surface.
8. Have quick access to a telephone in case of an accident.
9. Keep a first aid kit, ring buoys and reaching poles near the pool in case of emergency
10. Develop a buddy system: don't swim alone or allow others to do so.
11. Never dive into an above-ground pool.
12. Don't allow running near the edge of the pool.
13. Always check the water depth before plunging into an in-ground pool
14. Make sure teens understand the reasons and importance of the rules when it comes to pool safety.
15. Be watchful of alcohol consumption during pool parties and adult swims.
16. Don't allow glass bottles or other breakables in the pool area.
17. Keep radios, CD players, blow dryers, and other electrical devices away from the pool.
18. Ask the adults in your home to take basic First Aid and CPR training.
19. Remove automatic vacuums from the pool before swimming.
20. Keep pool chemicals locked away.
