An interlock between a drawworks and a blowout preventer includes a sensor for sensing a position of the blowout preventer. An interlock signal is generated by the sensor, and the interlock signal is reflective of the position of the blowout preventer. A lock operably connected to the drawworks receives the interlock signal and disables operation of the drawworks if the interlock signal meets a predetermined criterion. A method for operating a drill rig includes operating a drawworks to raise and lower a drill string and operating a blowout preventer. The method further includes sensing a position of the blowout preventer and generating an interlock signal that reflects the position of the blowout preventer. The method further includes comparing the interlock signal to a predetermined criterion and disabling the drawworks if the interlock signal meets the predetermined criterion.
