Referee's Signal Number 6 - Safety
This signal is used to denote the concession of a safety (2 points).
The hands should start at the waist and be extended until they meet over the head in an unhurried motion.
It should be accompanied or preceded by a loud blast on the whistle. If you are the on-field timekeeper, stop the watch before making the signal.
Maintain the signal until eye-contact has been established with the Referee, who will then turn and confirm the score by making the same signal to the press-box.
