Each rink should be provided with a buzzer or other suitable sound device to be used by the game timekeeper.

Each rink should be provided with an electric clock, allowing spectators, players and game officials to be informed of the TIME throughout the game. If the clock should have many faces, the one facing the game timekeeper shall be considered the OFFICIAL TIME.

The IBFA recommends the installation, whenever possible, of an electric buzzer or bell, and a well synchronized system with green light and electric clock, to ensure that the officials clearly see and hear the end of period or end of game signal. The beginning of the sound should have priority over the clock to indicate the end of the period. A light should also be provided to indicate the scoring of a goal.

In the event that the rink is not equipped with a permanent clock, a stopwatch or portable clock should be used.
