A man-down signal that someone can act on.
Lone worker safety with UWB RTLS: a man-down signal someone can act on. Test the dead-battery path — coverage dips must not kill the alert.
Duress, man-down and check-in for people working alone. Site evacuation accountability is mustering.
Lone-worker tech fails when the escalation path is unclear at 02:00.
Escalation tree
Duress without a tested on-call tree is liability. Drill the full path quarterly.
False alarm fatigue
Man-down sensitivity that cries wolf gets muted. Tune with real tasks, not a desk demo.
Coverage honesty
Basements and Faraday zones need repeaters or procedural controls. Do not pretend the pin always works.
Lone-worker & man-down protection: how it works, and what it protects.
The right radio for the job — chosen, never sold — mapped to your use case. That is what makes the ROI fast.
1 · Equip
Workers carry a wearable with duress button, fall and no-motion sensing.
2 · Detect
A fall, no-motion or duress press raises an alarm with the worker's live location.
3 · Respond
The control room is alerted instantly and guides responders straight to the spot.
UWB/BLE → indoor · GPS/LoRaWAN → remote & outdoor
Which technology actually fits.
Paid only by you. Hardware stays on the vendor’s paper.
UWB
Precise indoor duress location.
LoRa
Remote/outdoor coverage.
Man-down
Fall & no-motion sensing.
Industries this solution suits
Help that reaches them in seconds.
A utility equips field crews with wearables. A fall, no-motion or duress event raises an alarm with the worker's live position, the control room is alerted instantly, and duty-of-care is evidenced.
Typically bought by: EHS / HSE, control-room operations, HR, compliance.
Relevant case studies
Where this solution wins — examples by sector.
Oil & gas maintenance crews (oil-gas)
Confined-space, hot-work, lone-worker protection.
Mining underground personnel (mining)
Underground lone-worker safety with man-down detection.
Healthcare ED, psych, security (healthcare)
Staff safety against workplace violence.
Manufacturing 3rd-shift maintenance (manufacturing)
Solo maintenance during off-shifts.
Utilities field-service technicians (energy)
Remote field workers across grid and pipeline.
What buyers actually care about.
Help that arrives with a place, not a phone number. Duty of care for lone workers fails when an SOS reaches a mailbox with no location. Buyers need duress, fall/tilt and immobility (man-down) alerts that open with who, where and how long — routed to a human who can act at 02:00.
Detection that works when the worker cannot press a button. Unconscious or trapped workers never complete a check-in. Configurable no-motion and orientation thresholds, with a pre-alert cancel window to cut false positives, matter as much as the panic button.
Coverage honesty. Indoor locating, yard GNSS and cellular/satellite dead zones each leave different blind spots. The programme must map where monitoring is guaranteed, where it degrades, and what procedure fills the gap — especially mines, tanks, substations and night-shift plant.
Escalation that is owned. Technology without a named on-call chain, acknowledgement SLA and rescue playbook becomes noise. Buyers care about who is paged, who acknowledges, and what happens if nobody answers.
Evidence for regulators and insurers. Time-stamped alert logs, response times and coverage maps support OSHA-style monitoring expectations and local lone-worker rules — and defend the organisation after an incident.
Where lone-worker programmes fail.
False-alarm fatigue. Aggressive immobility thresholds on seated or kneeling tasks flood the desk; responders start ignoring alerts. Tune by role and zone, and require acknowledgement — do not “fix” noise by turning detection off.
Tag left in the locker. Wearables that are uncomfortable, non-ATEX where required, or not part of permit-to-work are abandoned. Pair devices with induction and gate checks, not hope.
Location without response. A beautiful map of a fallen worker is useless if the shift supervisor has no radio protocol and no second person nearby. Design the human system first; place locating under it.
Pilot on Wi-Fi only. Many industrial sites need UWB or private radio for reliable presence indoors, plus outdoor GNSS. Starting on consumer BLE in a metal plant proves the wrong thing.
How vendors pitch this vs what to buy.
Industrial safety locating vendors such as Litum, AiRISTA, WIPELOT and broader RTLS platforms (Sewio, Quuppa partners, Extronics hazardous-area tags) pitch UWB/BLE wearables with SOS, fall and man-down, heat maps and geofence alerts. Campus and workplace suites may offer panic and mustering without centimetre accuracy.
Buy the outcome stack: reliable detection modes for your tasks; location accuracy matched to rescue (room/zone vs metre); an escalation workflow with acknowledgement and audit; coverage survey before go-live; and the same badge layer reusable for mustering or zone access where it reduces kit. TRACIO stays vendor-neutral — we do not sell wearables or safety SKUs — and advise which product stack fits the duty-of-care model you can actually staff.

Frequently asked questions
How does lone-worker and man-down protection work?
A worn device combines location with man-down (no-motion or tilt) and panic-button detection, raising an alarm with the person's position so help reaches them fast.
Does it work where there is no GPS or cellular?
Yes - indoors and underground we use UWB or BLE anchors or mesh; outdoors GNSS; and we design for the dead spots, which is exactly where lone workers are most at risk.
Who gets the alert, and how fast?
Alerts route to your control room, security or designated responders with location and time, integrating with PA, mustering and existing alarm systems for a coordinated response.
How do we balance safety with worker privacy?
Location can be revealed on alarm rather than tracked continuously, and policies are agreed with workers and unions - protection without surveillance.
What standards does it support?
It underpins your lone-working risk assessments and duty-of-care obligations, with an auditable record of alerts and response times.
