There are lots of poolside safety, but I think the following is the most important:
+ You mustn't play in the wet place.
+ Adult supervision is required.
+ Don't jump onto the board too high.
+ Must carry a float when not able to swim.
+ Do not dive without an air tank.
+ Do not dive deep to open the lake cover.
+ Don't swim when you eat full.
