The orange safety bag is for runners and not outs. Also if your player sets up on it you may have an obstruction issue with the baserunner
Ideally the catcher steps into fair territory and throws the the fair side of first base. The runner has the running lane on the foul side of the chalk. On a PB/WP you have no choice but to throw in foul territory and place a tag instead of a foot rave to the bag
On a DK3, the orange bag ceases to exist. Both bags become white and F3 declares which bag she wants based on the catcher's instructions (inside/outside).
