Variants of lone worker protection

Lone worker Interval App

Lone worker app checks with a time interval

The Risk Inventory and Evaluation (RI&E) can determine that it is sufficient for your situation if the lone worker periodically receives an inspection message. This message is received as a push notification via the lone worker app and as a backup via a telephone connection. The interval is adjustable, just like who should be alerted. This can vary per location but also per time. If there is no response from the lone worker, a scenario is started.

Fall detection & motion detection in man down app

Our lone worker app / man down app has fall detection or motion detection similar to a lone worker device that functions as a man down device. If the sensors of the smartphone exceed a predetermined value, a lone worker alarm is sent that is including the location of the victim. The same applies if the victim does not move for a predetermined time, a so-called no-movement alarm is send. False alarms are prevented because the person in question has time to stop alarm in the man down app.

SOS emergency button in case of aggression

Alarm button/ panic button for lone worker safety

If your lone workers could face aggression, our lone worker app provides the ability to discreetly send an SOS alert without further escalation. This can be sent to colleagues nearby or an emergency center. They receive the location of that person and can listen in. There are various ways to start an alarm, with additional hardware, such as a alarm button / panic button on for instance the belt, or everything via the smartphone. Both solutions have advantages and disadvantages.

Working with a lone worker app or an extra device?

Our lone worker app offers the same security as traditional lone worker hardware, but with more functionalities, more ease of use and at a lower cost. The lone worker app has the K21023 Mobile Security certification, so you as an employer are assured that the safety of your employees is guaranteed.

Indoor and outdoor positioning

For lone worker safety a fast response of an emergency team is essential. For this, the colleagues must know where the lone worker is located. Outside, this is relatively simple and works based on GPS with an accuracy of a few meters. GPS often does not work sufficiently indoors, certainly not in high-rise buildings. It is possible to locate with Bluetooth transmitters, but this requires additional hardware. The indoor position determination of our lone worker app works with the existing WiFi routers and can thus locate people at floor level and section level. For the last meters, we work with a very loud signal on the lone workers smartphone.

Lone worker protection (LWP) with five-fold certainty

Our lone worker app is part of a certified emergency notification system that uses many different channels. The way in which colleagues can be reached differs per person but also per moment. The more channels used, the greater chance that the lone worker in need will receive help quickly.

    Faster help for lone workers through attendance registration

    Industry, municipalities, healthcare institutions and logistics service providers are the driving force behind our lone worker app. The automatic attendance registration makes it possible to only call colleagues who are nearby and who can help immediately. You can also be alerted in the event of understaffing. If there are too few colleagues in the area, MultiBel can send a notification to those responsible. Your employee is assured that sufficient help is always nearby and does feel protected.

    Lone worker protection & safety at work – what are the obligations?

    Many people work in risky conditions and/ or in a place where they work alone. As an employer, you are responsible according to the Working Conditions Act to provide your employees with a safe workplace and to identify the risks. This can also apply to people who work alone at home. The measures you must take as an employer to ensure that your employees can sound an alarm in case of an emergency or that an alarm is triggered immediately if an employee does not move, respond or man down alarm. It is precisely at these times that a reliable lone worker alarm is of great importance for reporting incidents. The solutions we have for this are suitable for all risk classes and very reliable.

    In the past, it was often relied on periodic checks by colleagues doing their rounds or additional lone worker devices. Modern technology provides more efficient shapes to ensure the safety of lone workers. If the Risk Inventory and Evaluation (RI&E) shows that a periodic check of the lone worker is sufficient then the lone worker will for receive a notification for instance every 2 hours. If there is no feedback, our lone worker app usually alerts colleague as a result no Private Alarm Central (PAC) needs to be used.

    Our lone worker app recognizes when people are no longer moving or when they are falling down. Our lone worker system also offers an alarm button and sends the location of the victim in case of an emergency. Because MultiBel knows through attendance registration which emergency team members or colleagues are present at that specific location, no time is lost.

    Would you rather use a Private Alarm Center than colleagues who are nearby? Per scenario or per function you determine in advance who will be alerted, who has insight into the reactions and who will have a speaking and listening connection with the victim.

    Customers are increasingly opting for our lone worker app, because it does not require any investment in hardware. Apart from the extra functionalities and ease of use, it is also a much more cost-effective solution than extra lone work devices.

    Lone worker at home – what are the obligations?

    More and more people are working from home. That was already a trend before Corona and it will only have increased after Corona. Usually, working from home does not increase the risk, but lone working at home does. Working without supervision or sight of colleagues is working alone. This means that, according to the Working Conditions Act, there must also be measures at home to guarantee the well-being of the lone worker. In such cases, the periodic check is an accessible, user-friendly and attractively priced option to fulfill your obligations as a good employer. The lone worker also feels supported at home in case of an emergency.
