A lone worker alarm is the device a lone worker carries to raise an alert after a fall, a medical emergency or an assault, manually or automatically. There are seven main families: smartphone app, smartwatch, dedicated device, panic button, satellite messenger, two-way radio and ATEX-certified equipment. The right choice depends on network coverage, the work environment and the main risk.

What is lone worker protection?

Lone worker protection (LWP) is the complete system that protects employees working alone: an alert device, a supervision platform and an alarm procedure. It is part of the employer's prevention approach, alongside personal protective equipment and organisational measures that reduce risks and ensure a fast response.

What is a personal safety alarm?

A Personal Safety Alarm (PSA) is the device that detects the incident and sends the alert: a smartphone with an app, a smartwatch, a dedicated device or a satellite messenger. It raises a distress alert manually (SOS button) or automatically (fall, immobility, loss of verticality), together with the worker's location.

Lone worker safety: a protection and compliance issue

Protecting lone workers benefits the whole organisation. An employee equipped with an alert device feels safe and stays focused on the job. The company shows it has put the necessary measures in place, which supports both compliance and its employer brand. And a personal safety alarm lets you respond faster to an accident and limit its consequences.

Lone Worker System: definition

One Lone Worker Device is a solution to protect an employee working alone, without the possibility of immediate assistance. It is an alert system capable of detecting risky situations (fall, immobility, loss of connection) and of quickly warning emergency services. There are various lone worker devices adapted to different missions.

What is the purpose of a lone worker device?

Imagine being alone at the end of the day at your desk. You get up to get a piece of paper from the printer on the floor below and you fall down the stairs. You lose consciousness, no one will come to help you until the next morning. This dramatic situation happens every day, a device for an isolated worker makes it possible in such a situation to automatically contact the emergency services.

Why deploy a solution for an isolated worker in a company?

An alert solution for a lone worker is beneficial at all levels for a company:

  • An employee equipped with an alert system will feel safe, and can be more focused on his work
  • A company that takes care of its employees will attract new candidates who are sensitive to the values defended by the company.
  • A company that sets up a system to protect lone workers will be able to legally protect itself by showing that it has put in place the necessary security measures.
  • A company that sets up an alert system will be able to intervene more quickly in the event of an accident and thus limit the consequences of the accident.

How do I choose the right device?

Have you identified lone workers in your company? Do you want to equip them with an alert device? Yes, but how do you choose? Several criteria must be taken into account:

  • Identify the available means of communication: Wifi, 4G, Satellite, Radio - Very often the choice of available communication technology will allow you to choose the solution adapted to your situation.
  • Work environment: Identify the constraints related to the missions of your employees: If workers work in a humid environment, a waterproof equipment will be essential. Explosive environment? The choice of an ATEX telephone is mandatory.
  • Acceptance: If your employees must use an alert deivce, be careful to choose equipment that suits them. For some a watch will be the ideal tool, while for others a mobile application will seem to be the most natural solution. A single watchword: communicate! It is never good to impose a device without consultation, at the risk of seeing the device in a drawer!
