Practical guidance

Use this as a factual briefing page for managers and staff

The advice below is written for UK employers who need lone worker devices, apps and monitoring arrangements to work in real conditions, not just appear in a policy.

Device selection

Start with the work, not the brochure

A device should be selected against the real lone working activity. Consider travel, isolated sites, public contact, clinical or enforcement duties, dogs, violence and aggression risk, signal availability, night work and the ability to summon help discreetly.

Map the highest-risk tasks before comparing suppliers.
Identify whether the main risk is violence, medical emergency, fall, remote location, missed check-in or inability to speak.
Test devices in the actual locations where staff work.

Device selection

Match features to realistic scenarios

The right specification depends on how the worker can act under pressure. A physical SOS button may be better than an app where speed and touch access matter. An app may be suitable where phones are already managed and carried. Satellite support may be necessary where mobile coverage is unreliable.

Physical button: stronger for fast or discreet activation.
App: useful where phones are managed, charged and routinely carried.
Satellite device: relevant for remote, rural or infrastructure work.
Fall or non-movement alert: relevant only where posture, terrain and false activation settings have been tested.

Device selection

Require evidence after purchase

Buying the device is not the end of the decision. Managers should review adoption, false activations, genuine alerts, missed tests, response times and staff confidence after roll-out. If the data shows weak use, the control needs review.

Key facts

Facts to brief into your lone worker arrangements

Use these points to check whether the topic is covered in your policy, training, device configuration and manager review.

A lone worker device is a control measure only when it is carried, charged, understood and connected to a response process.
Supplier demonstrations should be followed by workplace testing, not accepted as proof of suitability.
The cheapest device may be expensive if staff do not use it or if monitoring instructions are unclear.

Implementation standard

Apply buying the right device for the risk as part of a complete control system

A useful decision must connect the risk assessment, technology, worker behaviour and response arrangement. Use the stages below to turn this topic into an auditable working control rather than a statement in a policy or supplier specification.

1. Define the operating need: Record the role, task, location, foreseeable harm and point at which the worker may need contact or assistance. Identify what existing controls already prevent exposure and what gap this topic is expected to address. Do not use technology to justify work that should be redesigned, delayed or completed by more than one person.
2. Verify the service and its limitations: Obtain written confirmation of the function, connectivity, monitoring route, escalation instructions, retention periods, support arrangements and contract boundaries. Test supplier claims in representative workplaces. Record what happens when signal, battery, location, audio or the first responder is not available.
3. Configure around real work: Set accurate user profiles, task notes, contact details, response priorities and out-of-hours arrangements. Confirm who owns changes when workers move role, location or shift. A technically functioning service can still fail when the responder receives obsolete or vague information.
4. Practise the whole response: Rehearse preparation, activation, communication, cancellation, missed contact and post-incident reporting using the approved equipment and local process. Include the manager or monitoring route so the exercise tests what happens after the worker asks for help, not only whether they can press a button.
5. Review evidence and improve: Review test completion, non-use, false activations, missed check-ins, faults, alert handling, staff confidence and incident outcomes. Compare teams, shifts and locations. Agree an owner and completion date for any change to training, configuration, supervision, supplier arrangements or the underlying work.

Assurance questions

What managers should be able to evidence

The answers should be available without relying on one person's memory or a supplier presentation.

Which workers, tasks and locations this guidance applies to.
Which foreseeable risk the arrangement is intended to reduce.
Who receives an alert or missed contact first and who acts next.
Which limitations and fallback actions staff have been taught.
When the service was last tested in representative conditions.

Which staff and managers have demonstrated practical competence.
How faults, false activations and uncertainty can be reported safely.
What location, audio, incident and test evidence is retained.
How worker privacy and access to monitoring information are managed.
Who owns the next review and which events trigger an earlier review.

Evidence and limits

Use official guidance and verify product-specific claims

HSE guidance requires employers to manage the health and safety risks faced by lone workers, including training, supervision, monitoring and keeping in touch. It does not approve a particular device or guarantee that one technology is suitable for every role. Product functions, certification scope, response performance, network coverage and evidence access must be checked for the actual service and contract.

Location, audio, call records and monitoring data may contain personal information. Employers should identify a lawful and fair purpose, use proportionate monitoring, inform workers clearly, control access and set retention arrangements. Obtain competent data-protection advice where the processing is high risk or unclear.
