When someone works alone, their safety should never be left to chance.

Every day, thousands of people across the UK carry out their responsibilities without a colleague or supervisor nearby. From engineers maintaining equipment in remote locations to healthcare professionals making home visits, lone working is a necessary part of many industries.

However, working alone introduces risks that employers cannot afford to overlook.

What happens if an employee suffers a fall and cannot call for help? What if a worker is threatened or assaulted while carrying out their duties? How quickly would your organisation recognise that something was wrong, identify their location and arrange assistance?

These are questions every business employing lone workers should be able to answer.

Effective lone worker safety is about more than meeting health and safety requirements. It's about ensuring employees can carry out their jobs confidently, knowing that someone is looking out for them and that help can be arranged when they need it most.

With the right procedures, communication systems and monitoring technology in place, businesses can take a proactive approach to protecting employees, even when they are working in isolation.

What Is Lone Worker Safety and Why Does It Matter?

Lone worker safety refers to the measures, procedures and technologies that protect employees who work without close or direct supervision.

A lone worker doesn't necessarily have to work somewhere remote. Someone cleaning an empty office building, maintaining machinery in a factory or carrying out an inspection in a large warehouse may be considered a lone worker.

Similarly, delivery drivers, security personnel, healthcare professionals and engineers working across multiple sites can all face situations where immediate assistance is unavailable.

The challenges arise when something unexpected happens.

An employee working alongside colleagues can often receive immediate assistance following an accident. For someone working alone, an injury, medical emergency or threatening situation could go unnoticed.

The danger isn't always the incident itself. It's the possibility that nobody knows the incident has happened.

This is why organisations need robust lone worker safety procedures that allow them to maintain communication, monitor employee welfare and respond appropriately when an incident occurs.

Lone Worker Safety and Your Responsibilities as an Employer

Protecting lone workers is not simply good practice. Employers have legal responsibilities to manage the risks associated with working alone.

The Health and Safety Executive (HSE) explains that employers must assess and manage risks before employees undertake lone working activities.

This includes:

- Identifying hazards associated with working alone and taking appropriate steps to control them.

- Providing suitable training, supervision and support.

- Establishing reliable communication arrangements.

- Monitoring lone workers and maintaining regular contact.

- Implementing procedures for responding to emergencies.

- Reviewing the effectiveness of existing safety arrangements.

Employers must also consider whether certain activities are suitable for lone working at all.

Some high-risk tasks require additional personnel or specific supervision arrangements. Technology cannot make an otherwise unsafe working practice acceptable.

A risk assessment is therefore the starting point for any effective lone worker safety strategy.

However, identifying risks is only half the challenge.

Businesses must also demonstrate that the measures they have introduced work in practice.

For example, having a lone working policy is important, but what happens if an employee misses a scheduled check-in? Is somebody alerted? Who takes responsibility for investigating? How is the situation escalated if the employee cannot be contacted?

Without clear answers, even a well-written policy may fail to provide the protection employees need.

The Hidden Dangers of Working Alone

Lone workers can face many of the same hazards as employees working in teams. The difference is that they may have nobody nearby to recognise a problem or provide immediate assistance.

Several risks deserve particular attention.

1. Accidents, Falls and Medical Emergencies

An engineer working alone may slip while inspecting equipment. A warehouse employee could suffer an injury in an isolated area. A maintenance worker might experience a sudden medical emergency.

In each situation, the employee may be unable to reach a telephone or communicate their need for help.

Without an effective monitoring or alert system, valuable time could pass before anyone realises something is wrong.

2. Violence, Aggression and Threatening Behaviour

Employees working directly with members of the public can face unpredictable situations.

Healthcare professionals, transport employees, security personnel and retail workers may encounter aggression, threats or physical violence while working without immediate support.

Being able to discreetly raise an emergency alarm and request assistance can provide an important additional layer of protection.

3. Isolated and Remote Working Environments

Workers in renewable energy, utilities, construction and other geographically dispersed operations may be located a considerable distance from their colleagues.

A conventional telephone call may not always be practical, particularly in noisy workplaces, areas with limited coverage or situations requiring immediate communication with multiple people.

Organisations need communication systems suited to the environments in which their employees operate.

4. Missed Welfare Checks

One of the most easily overlooked risks is the failure to recognise when a lone worker hasn't checked in.

A missed call or unanswered message may appear insignificant. However, it could indicate that an employee has suffered an accident, encountered a threat or become incapacitated.

Relying entirely on manual check-ins can leave businesses vulnerable to human error, especially where supervisors are responsible for monitoring multiple employees.

5. Not Knowing Where an Employee Is Located

Even when an emergency alarm is raised, locating the individual can be challenging.

Large industrial facilities, multi-storey buildings, warehouses and remote outdoor environments can make it difficult for response teams to identify where help is needed.

The faster an organisation can establish an employee's location, the sooner it can direct an appropriate response.

Five Essential Technologies That Strengthen Lone Worker Safety

A comprehensive lone worker safety strategy should not depend on a single device or communication method.

Instead, it should combine several protective measures that work together to identify incidents, maintain communication and support emergency responses.

1. Automated Lone Worker Welfare Checks: Knowing Your Employees Are Safe

Regular welfare checks are one of the foundations of effective lone worker protection.

Traditionally, businesses may have relied on employees contacting their supervisors at agreed intervals. While this can work, it creates administrative demands and depends on individuals remembering to make and record each check.

Automated lone worker welfare checks provide a more structured approach. Using a suitable system, businesses can schedule regular check-ins based on the employee's role, working environment and level of risk.

If a worker does not respond within the required timeframe, the system can trigger an alert and initiate an agreed escalation procedure.

This helps organisations:

- Maintain regular contact with employees working alone.

- Identify missed check-ins without relying entirely on manual processes.

- Reduce administrative demands on supervisors.

- Create records of welfare checks and alerts.

- Establish a clearer and more consistent approach to monitoring employee safety.

For example, consider a maintenance engineer working alone during an overnight shift.

Rather than depending on a supervisor remembering to telephone periodically, scheduled welfare checks can help ensure the employee is monitored throughout their shift. If they fail to respond, the system can raise an alert so that someone investigates.

The objective is simple: a lone worker should not have to wait until somebody notices their absence before their safety becomes a concern.

2. Emergency Alarms and Fall Detection: Getting Help When Every Second Matters

Not every emergency gives an employee the opportunity to make a telephone call or explain their situation.

A worker experiencing a threatening encounter may need to request assistance discreetly. Someone who suffers a serious fall may be physically unable to communicate.

This is where dedicated emergency alarms and automatic fall detection can play an important role.

A lone worker safety device equipped with an SOS button allows employees to raise an alert when they need immediate assistance.

Depending on the device and system configuration, automatic fall detection can also recognise certain fall events and initiate an alert.

These capabilities can be particularly valuable for:

- Engineers maintaining industrial machinery.

- Security employees working alone.

- Workers operating in isolated areas.

- Healthcare professionals attending potentially challenging situations.

- Employees undertaking maintenance and inspection activities.

However, an alarm alone is not enough. Every alert must be supported by a reliable process that determines who receives it, who responds and how assistance is arranged.

An emergency alarm is most effective when it forms part of a clearly defined safety procedure that employees and supervisors understand.

3. Indoor and Outdoor Location Tracking: Knowing Where Help Is Needed

When an emergency occurs, knowing that an employee needs assistance is only the beginning.

The next challenge is establishing their location.

Consider a worker who raises an emergency alarm in a large manufacturing facility. The site may contain multiple production areas, storage buildings, loading bays and maintenance zones.

Without reliable location information, colleagues could lose valuable time searching for the employee. Indoor and outdoor location tracking can help organisations identify where lone workers are operating and direct assistance more effectively.

Depending on the equipment and infrastructure deployed, solutions may use GPS for outdoor environments alongside suitable indoor positioning technologies for complex buildings.

This can be especially beneficial in locations such as:

- Large manufacturing and processing facilities.

- Warehouses and distribution centres.

- Hospitals and healthcare estates.

- Petrochemical and industrial sites.

- Wind farms and other renewable energy facilities.

Effective location tracking must be designed around the working environment. GPS alone, for example, may not provide reliable positioning deep inside a building.

The goal is not simply to know where employees are. It's to make sure their location can be established when their safety depends on it.

4. Reliable Two-Way Communication: Keeping Employees Connected

Communication is fundamental to lone worker safety.

Employees need a dependable method of contacting supervisors, reporting hazards and requesting assistance.

Although mobile phones can provide a convenient communication method, they may not always be the most suitable option for challenging industrial or remote working environments.

Purpose-designed two-way radio systems and Push-to-Talk over Cellular (PoC) devices can provide alternatives.

Digital Mobile Radio (DMR)

DMR two-way radios offer dedicated voice communication for teams operating within supported radio coverage areas.

Depending on the equipment and system design, they can also support safety features such as emergency alarms, worker monitoring and location-related applications.

This makes them a useful option for industrial sites, manufacturing facilities, warehouses and other environments where dependable team communication is essential.

Push-to-Talk over Cellular (PoC)

PoC devices use cellular data networks, and in some configurations Wi-Fi, to provide push-to-talk communication.

This can make them suitable for employees travelling between locations or working across wider geographical areas.

For businesses employing mobile engineers, transport personnel and field-based employees, PoC technology can provide a practical way to maintain communication across supported network coverage.

The most appropriate solution depends on factors such as coverage, the working environment, battery performance, safety features and the organisation's operational requirements.

Both technologies can form part of a broader lone worker safety system, rather than operating solely as voice communication devices.

5. Centralised Lone Worker Monitoring: Bringing Safety Information Together

For organisations with multiple lone workers, monitoring individuals across different locations can quickly become complicated. A supervisor might be responsible for employees working in separate buildings, remote sites or different parts of the country.

Without a centralised system, safety information may be spread across telephone calls, messages, spreadsheets and individual devices. A centralised lone worker monitoring platform helps bring this information together.

By combining welfare checks, alarms, location information and communication capabilities, designated personnel can gain a clearer overview of lone worker activity. This can help organisations identify outstanding welfare checks, investigate alerts and coordinate assistance when required.

It also creates opportunities to review recorded activity, identify recurring problems and improve safety arrangements. Importantly, centralised monitoring should always be supported by clear responsibility for responding to incidents.

Technology can highlight a problem, but an effective human response remains essential.

TRBOCALL: A Connected Approach to Lone Worker Safety

One of the challenges businesses face is bringing different safety functions together without creating unnecessary operational complexity.

At Eemits Communications, our TRBOCALL platform helps organisations manage communication and lone worker safety through an integrated, cloud-based solution.

Rather than treating emergency alarms, welfare checks, location tracking and communication as entirely separate functions, TRBOCALL brings these capabilities together within a centralised system.

This provides a more connected approach to protecting employees across different working environments.

**Key TRBOCALL capabilities include:**

- **Automated welfare checks:** Schedule and manage employee check-ins, with alerts when required responses are not received.

- **Emergency alarm integration:** Enable workers to raise alarms using appropriately configured devices.

- **Fall alerts:** Support automatic alerts from compatible devices equipped with fall-detection functionality.

- **Location tracking:** Incorporate indoor and outdoor location information where suitable positioning technology has been deployed.

- **Centralised monitoring:** Provide supervisors and dispatch personnel with a clearer view of safety-related information.

- **Flexible device options:** Support suitable digital two-way radios, PoC devices and other compatible endpoints.

TRBOCALL is device-agnostic and can support different communication technologies, including Tier III DMR and Push-to-Talk over Cellular solutions.

Because the platform is cloud-based, businesses can reduce the need to manage complex server infrastructure themselves. For organisations with employees working across multiple sites, this flexibility can be particularly valuable.

Crucially, TRBOCALL is not intended to replace sensible risk management, employee training or established emergency procedures.

It provides technology that can help businesses put those arrangements into practice more consistently.

Lone Worker Safety Across Different Industries

Lone working risks vary significantly depending on the industry, which is why there is no single solution suitable for every organisation.

Manufacturing and Food Production

Manufacturing facilities can contain machinery, moving vehicles, noisy production areas and isolated maintenance locations.

Employees working outside normal production hours may face additional risks when fewer colleagues are present.

Automated welfare checks, emergency alarms and suitable indoor location technology can provide additional protection for employees carrying out inspections, cleaning and maintenance tasks.

Petrochemical and Hazardous Environments

Petrochemical facilities can expose workers to challenging conditions and potentially hazardous atmospheres.

In areas where explosive atmospheres may occur, communication equipment must be appropriately selected for the relevant hazardous area classification.

Suitable ATEX-rated radios can support communication and safety applications where the device, system and installation meet the required specifications.

When combined with defined working procedures and emergency response arrangements, these technologies can help strengthen protection for employees working in higher-risk locations.

Healthcare

Community healthcare workers, visiting nurses and other professionals may regularly work away from colleagues. They can face risks associated with medical emergencies, unfamiliar surroundings, aggression and unpredictable situations.

Accessible emergency alarms, reliable communication and structured welfare checks can help ensure these employees have a clear way of requesting support.

Transport and Logistics

Drivers, mobile personnel and warehouse employees can spend long periods working away from direct supervision.

For employees travelling between locations, communication systems with suitable wide-area coverage can help maintain contact with colleagues.

Scheduled welfare checks and location-related capabilities can also support organisations in monitoring employee safety across dispersed operations.

Renewable Energy

Wind farms, solar installations and other renewable energy facilities can involve remote locations, extensive sites and isolated maintenance activities.

Employees may work considerable distances from colleagues, making effective communication and emergency planning especially important.

A combination of suitable communication coverage, welfare monitoring, emergency alarms and location information can strengthen existing safety arrangements.

However, tasks with particularly high risks must still be assessed individually to determine whether lone working is appropriate.

Why Lone Worker Safety Should Never Be Treated as a Box-Ticking Exercise

There is an important difference between having a lone working policy and having an effective lone worker safety strategy.

A policy may explain that employees should check in with their supervisor. But does the organisation know whether those checks actually happen?

A risk assessment might identify the possibility of falls or accidents. But can an employee raise an emergency alarm if they are injured?

A business might provide every worker with a mobile phone. But has it checked whether suitable communication coverage exists in the locations where those employees work?

These questions highlight why lone worker safety cannot be reduced to completing paperwork.

Protecting employees means making sure the systems, procedures and people responsible for their wellbeing work together.

It also means regularly reviewing safety arrangements as working environments, staffing levels and operational risks change.

For employers, the consequences of inadequate protection can be serious.

Beyond the potential for injury or harm, incidents can disrupt operations, affect employee confidence and expose weaknesses in an organisation's health and safety management.

Most importantly, there is a human cost that should never be overlooked.

Every employee should be able to carry out their work knowing that appropriate measures have been taken to protect them.

Five Questions Every Employer Should Ask About Lone Worker Safety

If your organisation employs people who regularly work alone, consider the following questions.

1. How do we know our lone workers are safe throughout their shifts?

Are regular welfare checks taking place, and is there a clear escalation process when an employee fails to respond?

2. Can employees raise an emergency alarm when they cannot make a telephone call?

Do workers have access to suitable emergency alerting devices, including automatic alerts where appropriate?

3. Can we identify an employee's location during an emergency?

Have you considered the challenges of locating employees in remote outdoor areas, complex buildings or large industrial sites?

4. Is our communication system reliable in every area where employees work?

Have coverage, device suitability and potential communication failures been assessed?

5. Do we have a documented and tested emergency response procedure?

Does everyone understand who receives an alert, who responds and what actions should follow?

If you cannot confidently answer these questions, it may be time to review your existing lone worker safety arrangements.

Protecting Lone Workers at All Costs Starts with Taking Action

No organisation can remove every workplace risk.

However, businesses can take meaningful steps to reduce the likelihood of incidents, improve the speed at which problems are identified and ensure employees can access support when needed.

Effective lone worker safety requires more than issuing a device or introducing a written policy.

It demands an approach that combines appropriate risk assessments, employee training, reliable communication, regular welfare monitoring and effective emergency response procedures.

Technology such as automated welfare checks, emergency alarms, fall detection and location tracking can provide valuable support.

But the most important factor is ensuring those capabilities are properly implemented, maintained and backed by people who know how to respond.

When employees work alone, they should never feel that they are facing workplace risks alone.

At Eemits Communications, we help organisations strengthen their lone worker safety arrangements through solutions designed around their working environments and operational requirements.

From digital two-way radios and PoC devices to our cloud-based TRBOCALL platform, we can help bring communication, monitoring and emergency alerting together.
