Digital Lock-Out Tag-Out (LOTO) System for Mines and Industrial Plants

When equipment is isolated for maintenance, every lock and every key must be accounted for. Simpology's digital lock-out tag-out system replaces paper permits and manual lock boards with electronic control, so equipment can't be re-energised until every person working on it has signed off.

How digital LOTO works

  1. An authorised person starts the isolation and the system releases the correct isolation keys or locks.

  2. Each worker applies their personal lock and is recorded against the job.

  3. Isolation keys stay secured in the SIMSAFE cabinet until every worker has removed their lock.

  4. Every step is time-stamped and linked to a named user, giving a complete audit trail.

Why switch from manual lock-out tag-out?

  • Zero harm: removes the risk of a key being taken or equipment being energised while people are still working on it.

  • Critical valve and energy isolation: controls lock-out of critical valves, electrical isolators and other energy sources.

  • Full audit trail: see who isolated what, when, and who signed off, without searching through paper permits.

  • Secure access: users identify with PIN, card, QR code, biometrics or iButton.

  • Compliance: supports your mine health and safety and OHS lock-out procedures. Our Altair Platform is highly configurable to acomodate each client's specific business and safety process.
