Connected Worker Safety | Products

Overview

Connected Worker Safety is a wearable safety system for stevedores, lashers, mechanics and any worker on the port apron. A chest-harness or helmet-mounted device streams vitals, GPS and accelerometer data, runs fall-detection and proximity algorithms on-edge, and pages medics and supervisors the moment something goes wrong.

Built for ports, terminals, refineries, shipyards and construction sites that need to slash TRIR (Total Recordable Incident Rate), prove ISO 45001 compliance, and bring rescue time on a fallen-worker incident down from minutes to seconds.

Fall detection — 3-axis CNN classifier with 8-second no-move confirmation
Geofence proximity — warns when a worker enters a crane / yard-tractor operating zone
Panic / SOS button — 3-press immediate page to medic + supervisor + HSE
Vitals streaming — heart rate, body temperature, optional gas (H₂S / CO / O₂)

How It Works

Worker wearable — a chest-harness device (or helmet sensor) carries GPS / RTK, 3-axis accelerometer, PPG heart-rate, skin-temp, optional gas head, SOS button, status LEDs and a 16-hour battery. Hi-vis vest and hardhat RFID tags confirm PPE compliance.
Safety algorithms — on-edge models run fall-detection (signature in the accel trace), proximity logic (distance to crane / yard-tractor geofence), heat-stress prediction (HR + body temp), and gas-STEL evaluation. The trigger library is configurable per shift / zone.
Safety cloud — aggregates the fleet, plots 12-week incident trend, tracks TRIR / LTI / dwell, and produces ISO 45001 audit-ready evidence.
Officer response — medic, supervisor and HSE officer get a colour-coded SOS card on their phone with one-tap EN ROUTE / CALL, a fleet ticker, and a 144-worker safety roll-up.

The purple feedback loop pushes acknowledgements, rescue-en-route confirmations and zone evacuations back to every wearable.

Features

Edge fall-detection — CNN classifier on 3-axis accelerometer, no-cloud dependency
RTK GPS — sub-metre location even on container yards with multipath
Crane / equipment proximity — pulls live crane / yard-tractor positions, audio-warns workers
Vitals (HR + body-temp) — medical-grade PPG and skin-temp, 2-second cadence
Gas head (optional) — H₂S, CO, O₂, LEL for tank-cleaning / confined-space work
PPE-compliance check — RFID tags on hardhat and vest, no-PPE warning
Heat-stress prediction — ML model on HR + skin-temp + ambient + workload
ISO 45001 audit pack — incident, near-miss, training, drill evidence ready to export

Use Cases

Stevedoring & lashing crews — fall protection on container stacks, vessel deck
Crane & equipment operators — proximity warning when ground crew enters swing radius
Reefer technicians — lone-worker monitoring in remote reefer stacks
Confined-space & tank cleaning — gas + vitals + man-down with rapid evacuation
Refinery / chemical sites — H₂S monitoring with auto-evacuation paging
Construction / shipyard — height workers, hot-work permits, drill compliance
