Safety zones are all areas within 150 yards (450 feet) of an occupied building, house, cabin, or any barn or other building used in a farm operation. No person, including archery and crossbow hunters, may hunt or discharge a firearm, crossbow or bow in a safety zone, or shoot at any wild animal or wild bird within a safety zone, without the written permission of the owner or occupant of such safety zone. The safety zone applies to hunting only. It does not apply to indoor or outdoor shooting ranges, target shooting, law enforcement activities or the discharge of firearms, crossbows or bows for any non-hunting purpose.
