Pool Safety Tips for Kids

On a hot summer day, there are few things that are more appealing than a nice cool pool.1. And it is completely relaxing. Of course, if you have children, there are certain safety measures you should take, whether you have a pool in your backyard or are going to a public pool.

Go swimming together. No person should ever swim alone. Though many people do, the simple truth is that it only takes a second to become injured or drown.2.Having someone there with you can make the difference between life and death. This is especially true for young children. If your child is under the age of 5, you should never allow them to swim out of arm’s length.

3.Kids love to chase one another through the water. But it is important that you emphasize to your children that at no time should they be running around the pool or pushing anyone. In the water, teach children not to jump on top of one another and to watch their surroundings, so that they do not accidentally knock into others, injuring them. Playing around in the pool is very interesting but dangerous.

Keep it locked. If you own a pool, you must have a locking gate around your pool.   4.Keep the gate locked at all times, even when you are physically in the pool. It is terrible for children to steal into the pool.

Know the way out.5.Make sure that they know where all ladders are, and that you teach them to use them for entering and exiting the pool safely. Although your child may be able to lift herself or himself out of the pool using the side, that is not the safest way to go.
