Safety on the Beach!

Experts recommend never digging a hole deeper than the knee height of the shortest person in your group – with 2 feet being the maximum depth.
When either the sand forming the hole dries out or someone stands near the edge of the hole, adding extra weight, the sand hole collapses in, and the heavy grains fill all open spaces in the hole. This leaves no air available for a trapped person to breathe.
While skiers trapped in avalanches can cup their hands to form an air pocket because snow is light, but that’s not the case when sand collapses.
