Move behind trees or hills or anything that will block the ball from hitting you. Another option is to move to an area away from the landing zone.
You can also put up a ball barrier: two posts with netting strung tight between them. Personal protective equipment, such as a hard hat, will reduce the risk, but not enough for you to be safe while working in areas of flying golf balls.
When performing mobile work, like mowing, avoid working in the dangerous carry zone. Whenever golfers approach, move beyond the carry zone or go to another hole to work. Position yourself behind hills and trees that will block flying golf balls. You can also ask the golfers to “wait a minute” with hand signals.
Stationary Work: If you’re doing work in one place, like in an irrigation hole, leave as golfers approach the area.
Protecting Golfers: Certain maintenance work like the use of mowers.
