A suspender disengagement detection apparatus for a washing machine, comprises pressure sensors (5, 6) and a controller. The pressure sensors (5, 6) are mounted on at least one of a joint of at least one suspender (2) among a plurality of suspenders (2) and a housing (1) of the washing machine and a joint of the suspender (2) and a suspender base of an outer tub (3) of the washing machine, and the pressure sensors (5, 6) are electrically connected to the controller. The controller is electrically connected to a drive motor of the washing machine. A safe operation method for the washing machine, comprising: in a working process of the washing machine, by mounting the pressure sensors (5, 6) on the joint of at least one suspender (2) and the housing (1) of the washing machine and/or the joint of the suspender (2) and the suspender base of the outer tub (3) of the washing machine to detect a pressure, and feeding a detection result back to the controller; and determining, by the controller, whether a suspender (
