Abstract
This invention of Smart LOTO solves frequent safety violation of “Lock Out Tag Out” practice. While the violations often caused by poor human behavior of forgetting or ignoring the LOTO practice during maintenance, the Smart LOTO equipped with the following method and system to eliminate the human error: S1: Smart LOTO monitors the off signal from the energy source switch; S2: when Smart LOTO confirmed the energy source switch is in off position, the biometric data such as fingerprint or face recognition will be compared between the personnel who triggered and the data in the system, once authenticated, the self-locking mechanism will be activated to lock up the switch. S3: Smart LOTO will then upload Information such as Who, When, where, How Long wirelessly to the cloud platform for analysis purpose. This invention can enhance the overall safety aspect of the LOTO practice.
