Rule 6-8b, 33-2d - Suspension of play due to a dangerous situation

When play is suspended by the Management for a dangerous situation, If the players in a match or group are between the play of two holes, they must not resume play until the Management has ordered a resumption of play. If they are in the process of playing a hole, they must discontinue play immediately and not resume play until the Management has ordered a resumption of play. If a player fails to discontinue play immediately, he/she will be disqualified.

The following signals are generally used and it is recognised that all managements do the same.

Discontinue play immediately: One prolonged note of siren.

Discontinue play: Three consecutive notes of siren repeated. Resume play: Two short notes of siren, repeated.

In the above cases, players should mark their ball and when play is resumed return to complete the round.
