LOTO Worker is intended to assist Workers who perform maintenance work in a factory or plant, to digitally block the openings of LOTO Procedures that have been installed. Thus, with the digital lock in place, no one would be able to open the LOTO locks that have been placed on LOTO Points, until the moment in which the Worker removes it from the LOTO Procedure. In this way, Workers can perform maintenance work safely, without the need to travel to a certain location where they can place a lock on a key box.
