What BS 8484 is — and why procurement asks for it
BS 8484 is the British Standard for lone worker device and service provision. It doesn't make lone working legal or illegal — your duty of care to lone workers comes from health-and-safety law regardless. What BS 8484 does is give buyers a yardstick: a way to check that a lone worker solution and the monitoring behind it actually meet a recognised quality bar, rather than being an app someone knocked together.
That's why it turns up in tenders and insurer conversations. If a solution is BS 8484-aligned and its alarm receiving centre is accredited, a procurement or H&S manager can point to a standard instead of taking a supplier's word for it. It's shorthand for 'this has been done properly.'
The four jobs a lone worker alarm actually has to do
Strip away the marketing and every lone worker solution has to do four things. One: let the worker raise an alarm deliberately — a discreet SOS they can trigger without escalating a tense situation. Two: raise the alarm when they can't — man-down and fall detection for the incidents where the worker is unconscious, injured or unable to reach for a phone. Three: locate them — an accurate, live location so help goes to the right place, including where the mobile signal is poor. Four: reach a real responder — the alarm has to land with someone who will act, not just log a notification.
A solution that only does the first one — a panic button with no automatic detection and no monitored response — leaves the biggest risks uncovered. The worst lone-worker incidents are exactly the ones where the person can't press anything.
App or dedicated device?
Dedicated hardware devices have their place, but a modern phone-based app now covers most lone workers better and cheaper: the worker already carries the phone, it has GPS, a data connection and a speaker, and pairing it with a smartwatch adds fall and impact detection on the wrist. The right question isn't 'app or device' — it's whether the solution does the four jobs above reliably, with a proper response behind it.
The part buyers miss: the response chain
This is where cheap solutions fall down. An alarm is only worth what happens after it fires. When an SOS or a man-down alert goes off, who receives it? How fast? Do they have the worker's location, their profile, and an escalation plan — or just a red dot on a map? A monitored response, backed by a clear escalation path, is the difference between an alert and a rescue.
This is exactly why Vygard pairs its detection with Howie, an AI dispatcher copilot that briefs the responder in seconds — who the worker is, where they are, what triggered the alarm and what to do next — so the response starts immediately rather than after someone works out what's happening.
Match the solution to the actual risk
A community nurse, a forestry contractor, an oil-and-gas technician and a housing officer face very different risks — and a one-size box serves none of them well. The better approach is a core lone worker platform tuned to the sector: chainsaw-kickback detection for forestry, welfare checks and escalation for care, ATEX-rated handling for hazardous environments. Vygard runs 12 vertical sector packs on one platform for exactly this reason — the same reliable SOS, man-down and monitored response, tuned to the job.
Where to start
Start from the risk, not the hardware. Write down the realistic worst-case incidents for your lone workers, then check any solution against the four jobs and, above all, the response chain. If you'd like to see how Vygard handles SOS, man-down and monitored response for your sector, book a demo or talk to our team — we'll walk it through against your actual risk assessment.
Frequently asked questions
- Is BS 8484 a legal requirement?
- No. Your legal duty to protect lone workers comes from health-and-safety law regardless of any standard. BS 8484 is a quality benchmark for lone worker devices and monitoring — it's how buyers and insurers check a solution has been done properly, which is why it appears in tenders.
- Do I need a dedicated device, or is an app enough?
- For most lone workers a phone app — ideally paired with a smartwatch for fall and impact detection — covers the four essentials better and more cheaply than dedicated hardware. What matters is that the solution reliably raises alarms deliberately and automatically, locates the worker, and reaches a real responder.
- What's the most overlooked part of a lone worker solution?
- The response chain. An alarm is only worth what happens after it fires — who receives it, how fast, and whether they have the location and context to act. A monitored response with a clear escalation path is the difference between an alert and a rescue.
