Final answer:
The back official points to the face-off direction, takes three forward strides, turns to skate backwards, gives the icing signal near the blue line, and continues backwards to the face-off spot when icing is called.
Step-by-step explanation:
The sequence of actions for the back official when play has been stopped for an icing infraction is as follows:
The back official points in the direction of the face-off while monitoring for altercations. They then take three forward strides towards the face-off spot. After the strides, the official turns to skate backwards to the face-off location, continuing to watch the players.
Close to the blue line, they give the icing signal while still skating backwards. The official continues this until they reach the designated face-off spot. While skating backwards, the official maintains full view of the players. Finally, in the vicinity of the blue line, the official gives the icing signal and continues to skate backwards until reaching the face-off spot.
