A lockout closure includes an interlock device and a closure panel. The interlock device may be operatively coupled to a moving device and have a movable switch mechanism for interrupting operation of the device. The closure panel may have an engagement surface movable with respect to the interlock device in order to interact with the switch mechanism. The closure panel may be movable between an open position, in which the closure panel is positioned to uncover an access opening, and a closed position, in which the closure panel is positioned to cover the access opening. When the closure panel is in the open position, the engagement surface engages or disengages the switch mechanism so that the interlock device interrupts operation of the moving device.
