Know your swimming limits and stay within them. Don't try to keep up with a stronger skilled swimmer or encourage others to keep up with you. Keep an eye on weaker swimmers—if they appear tired, encourage them to get out of the water and rest.
Watch out for the "dangerous too's"—too tired, too cold, too much sun, too much strenuous activity. Get out of the water immediately if any of these situations occur.
Use common sense regarding food and beverages while swimming.
Do not chew gum or eat while you swim; you could easily choke.
Never drink alcohol and swim.
Use common sense about swimming after eating. If you have had a large meal, it is wise to let digestion get started before doing strenuous activity such as swimming.
Use plastic instead of glassware in the pool area.
Obey "No Diving" signs. A general rule is to enter feet first into water than head-first.
Never dive into an aboveground pool. They are too shallow.
Make sure the pool cover is completely lifted off the pool. Never walk on the pool cover.
Watch the weather: Know local weather conditions and prepare for electrical storms. Because water conducts electricity, stop swimming as soon as you see or hear a storm.
Keep rescue equipment (pole, rope and personal floatation devices) by the pool.
Keep a phone poolside. Program the phone with emergency phone numbers and/or post emergency phone numbers in your pool area.
Learn cardiopulmonary resuscitation (CPR) and basic first aid. Post CPR instructions in your pool area.
Special Precautions for Children:
ALWAYS supervise children when they are in or around your pool or any water environment (stream, bath tub, toilet, bucket of water), no matter what skills your child has acquired and no matter how shallow the water.
Install physical barriers around your pool and spa to prevent access by young children.
Fences should be at least four feet high with self-closing, self-latching gates, which are kept in good working order. Don’t leave any furniture near the fence so that a child could climb over into the pool area.
If your house forms one side of the barrier to the pool, then doors leading from the house to the pool should be equipped with alarms that sound when the doors are unexpectedly opened.
For additional protection, use a power safety cover (a motor-powered barrier placed over the water area).
For aboveground pools, steps and ladders to the pool should be secured or removed when the pool is not in use.
