Always have an adult nearby. Even if you are a great swimmer, you never know wehn you might need help.
Always check the water depth. You don't want to get hurt divining in water that is to shallow.
Always wear sunscreen. Without it, you could end up with painful sunburn.
No running! You could trip or slip - hurting yourself or others.
Secure all gates with locks. The best gates are self-closing & self-latching. Position latches well out of the reach of children. Install a gate alarm that will alert you inside the house if the gate is opened.
Install a pool gate. Experts recommend a fence of at least four feet tall, with slats close enough together that kids can't squeeze between them.
Stop swimming or boating as soon you hear a storm.
Always swim with a buddy!
