    Prove LOTO control
    across complex industrial work.

    Track what’s locked out, who’s signed on, and what’s ready for release — without chasing paper, spreadsheets or manual updates.

    The problem

    Blind spots become the risk.

    When lockout work spans sites, crews, contractors and shifts, teams need more than a paper procedure. They need to know what is isolated, who is signed on and what can safely be released.

    Supervisor asks
    • ASSETWhich equipment is locked out?
    • CREWSWho is working under it?
    • ISOLATIONWhat has been isolated?
    • VERIFYWas it verified in the field?
    • HANDOVERWhat changed between shifts?
    • RELEASEWhat can be returned to service?

    Zentri answers every question from a single live lockout record.
