When the puck is shot or deflected in such a manner as to produce a possible icing situation, the back linesman will signal to his partner by raising his non-whistle hand over his head (same as Slow Whistle). The instant that the conditions required to establish “icing the puck” have occurred, the front linesman will blow his whistle to stop play and raise his non-whistle hand (same as Slow Whistle). The back linesman will give the icing signal by folding his arms across his chest.
