Lone worker & safety
Wearable alarms and apps that let lone and remote workers raise help instantly, share their location and detect a fall. On multi-network SIMs, because a safety device that cannot connect is not a safety device.
What it does
Lone worker devices let someone raise an alarm discreetly, send their location and, in many cases, open a voice channel so the person responding can hear what is happening.
Some also detect a fall or a lack of movement and raise the alarm automatically, for the moments when the worker cannot.

A discreet button that raises help immediately.
The worker’s position sent with every alert.
An automatic alert if a worker falls and does not get up.
The responder can hear, and speak to, the worker.
Who needs it
Employers have a legal duty to assess the risks of lone working and put sensible measures in place. These are the roles we see most.
Working in customers’ homes, plant rooms and remote sites.
Night shifts, empty buildings and patrols.
Home visits where a situation can change quickly.
Coverage matters most here. A single-network device can fail in exactly the basement or rural lane where it is needed. A multi-network SIM uses whichever network is strongest.

The device, the connection and the response all have to work. The chain is only as strong as its weakest part.

Alerts go to your own team or a monitoring centre, around the clock.

Standards and monitoring
An alert is only as good as the response. Some businesses route alarms to their own team; many use an alarm receiving centre that answers around the clock.
In the UK, BS 8484 is the standard for lone worker device services. If you need a certified service, the device and the monitoring centre must both support it. We make sure the connectivity is never the weak link.
If your lone worker devices keep dropping signal, the SIM is often the problem rather than the device. We can supply multi-network SIMs for most devices.

Common questions
A wearable alarm, fob or app that lets someone working alone raise help quickly, usually sending their location and sometimes opening a voice call.
Employers must assess the risks to people who work alone and put sensible controls in place. The HSE publishes guidance on protecting lone workers.
The British Standard for lone worker device services. It covers the device, the service and the alarm receiving centre that responds.
Because a device that cannot connect cannot raise an alarm. A multi-network SIM uses whichever network is strongest, reducing dead spots.
