An alarm that only the wearer sees has not been managed. The person knows they broke the rule and nobody else does — so nothing moves: no correction, no briefing, no record. Escalation is what turns a device alarm into a management action, and it works when the levels are deliberately uneven: each one triggered less often than the one below it.
We route harness alarms through three levels. All of them are configured when the job record is created, not after an incident.
Level one: the device warns the wearer where the work is happening
Detection and classification run on the monitor itself, so they keep working where there is no network. The states that matter are read off the harness directly: a hook that was never connected, anchorage below the attachment point, a lanyard dragging on the ground, contact with scaffolding, work too close to an edge. The main unit alarms on the spot with sound and light at 75 dB. This is the one level that can change the outcome in the same minute, because the worker is still on the structure and can still correct the action before it becomes a fall.
Level two: the on-site safety officer is notified
Inside the same job, the officer responsible for that person receives the incorrect-wearing notice by phone call, SMS or messaging app, according to configuration. Nobody has to watch a screen. A violation moves from something found on patrol to something pushed to a named person while the job is still running — which is the difference between a record and a correction.
Level three: habitual violations reach management
For repeat offenders and staff under close supervision, the notice escalates to the leadership level through the same three channels. The platform summarises violation counts by day and by week and lists the people who need closer monitoring, so a review meeting runs on counted events rather than on recollection. Supervision is aimed at the people who keep needing it instead of at the whole crew.
What gets configured, and where
The three levels are set up when the job is created: choose the alarm items that apply, set the supervision level, then bind each harness monitor to a named person. Where a barometric calibrator is fitted, the device enters height-supervision mode only above the set height — 2 m by default — so a crew walking around at ground level does not generate a stream of alerts that trains everyone to ignore them. Calibration belongs in the pre-shift routine; a wrong baseline either counts flat walking as climbing or misses low-level work.
The monitor governs the process, not the load. It alarms on whether the harness was used as required. It does not take arrest forces and does not replace the harness, the fall arrester or the anchorage. Equipment is still selected and configured to GB 23468-2025, and the monitor fits the harness you already own rather than replacing it.
