Lone Worker Device and App Systems
Lone worker devices and smartphone apps provide a safety lifeline for construction workers operating alone. These systems can detect falls, trigger panic alarms, and send GPS locations to a monitoring centre when a worker fails to check in. Understanding how to use the device correctly is essential because a system that is switched off, uncharged, or misunderstood provides no protection at all.
Key Hazards
Lone worker unable to call for help after a fall or medical emergency
Device switched off or uncharged rendering the safety system useless
GPS signal lost inside buildings or underground preventing location tracking
Worker failing to check in triggering false alarm and wasting emergency response
Control Measures
- Carry the lone worker device or have the app active on your phone throughout every lone working shift.
- Charge the device fully before each shift and carry a backup charger for extended working periods.
- Complete a check-in at the intervals specified in your lone working risk assessment.
- Test the panic alarm function at the start of each shift to confirm it is working correctly.
- Ensure your monitoring centre has your correct site location and expected working hours each day.
- Report any areas with poor GPS or mobile signal to your supervisor so alternative arrangements can be made.
- Respond to welfare check calls from the monitoring centre promptly to avoid triggering a false alarm.
- Know how to activate the panic alarm and the man-down tilt detection feature on your device.
