Abstract: The present invention relates to a method, controller, wind turbine and wind farm that advantageously determines an ice throw risk zone (302) for a wind turbine (301), wherein the ice throw risk zone (302) defines an area surrounding the wind turbine (301) within which ice can be thrown from one or more blades of the wind turbine (301); determining whether the determined ice throw risk zone (302) impinges one or more exclusion zones; and if the determined ice throw risk zone (302) impinges one or more exclusion zones, determining an alteration to one or more operating parameters of the wind turbine (301) in order to alter the ice throw risk zone (302) such that the determined ice throw risk zone (302) does not impinge the one or more exclusion zones.
