Taking Relief
If your ball ends up in a bunker, please take appropriate relief according to Rule 16 (Relief from Abnormal Course Conditions), with particular reference to 16.1b on how to take free relief: https://www.randa.org/en/rog/the-rules-of-golf/rule-16
If the greens staff are working on a bunker near where you are playing, please allow them time to move to a safe place, or indicate it is safe for you to play, before taking your shot.
