Abstract
A system for monitoring a lockout condition of a component includes a lockout device, a lock unit, and a reader. The lockout device is moveable between a lockout condition blocking operation of the component and an access condition permitting operation of the component. The lock unit is configured to be secured to a lockout interface of the lockout device to secure the lockout device in the lockout condition. One of the lockout device and the lock unit includes a communication module configured to communicate a data signal including an identification code identifying the one of the lockout device and the lock unit. The reader is remote from the one of the lockout device and the lock unit, and is configured to receive the data signal at least when the lockout device is assembled with the component and the lock unit is secured to the lockout interface of the lockout device.
