Children aren’t the only ones who love the sand..so do insects and animals. Once installed, a sandbox should be covered when it isn’t in use.
If sand gets wet, it can harbor bacteria. Make sure to let the sand dry out thoroughly before covering if for the night.
Sand should be raked regularly to remove debris, clumps, or other foreign material.
Do not allow your household pets to play with your child in the sandbox. They may mistake it for the litter box.
In 1986, concern was first expressed that some types of commercially available play sand contained tremolite, a fibrous substance found in some crushed limestone and crushed marble. It was thought that the long-term effects of exposure to tremolite would be identical to those of asbestos. Despite these concerns, however, the US Consumer Product Safety Commission (CSPC) denied a petition prohibiting marketing of play sand containing significant levels of tremolite. The CSPC currently has no standards or labeling requirements regarding the source or content of sand.
