Zusammenfassung:	A method for protecting personnel working in a wind turbine nacelle or hub includes monitoring a nacelle roof hatch and a hub access hatch, each hatch having a switch configured therewith. When at least one of the hatches is detected as opened, a control system detects if a rotor lock has been engaged. If the rotor lock has not been engaged, the control system triggers a rotor brake to stop rotor and drivetrain component rotational movement and actuates a first control lockout between the respective switch configured with the open hatch and the rotor brake. The control system also initiates a control lockout that prevents release of the rotor brake until the switch indicates that the open hatch has been closed and the first control lockout has been reset.
