A safety base is a double bag at first base. It looks like 2 bases setting next to each other and one is typically orange. This is used to avoid collisions between the runner and fielder.
In baseball, a base is "safe" in that a player can not be tagged out if they are on the base before either they, or the base in some instances, are tagged.
