    The problem

    Scattered LOTO evidence becomes the problem.

    When maintenance work is reviewed, teams need more than a procedure. They need to prove what happened.

    Auditor asks
    • PROCEDUREWhich procedure was used?
    • WORKERSWho was signed on?
    • ISOLATIONWhat was actually isolated?
    • VERIFYWas the isolation verified?
    • CLOSEOUTHow was the work closed out?
    • EVIDENCEWhere is the record?

    Zentri answers every one of these questions from a single, connected lockout record.

    Product workflow
