Lone Worker Safety Solutions


Emergency protection.

Do you comply with the legal requirements regarding lone worker safety? Are people working alone in the workplace able to use personal security devices to call for help at any time in an emergency? Does your organisation have reliable monitoring in place, including an automatic emergency call facility, to cover emergency situations?


The SOS-Portal is a web-based, redundant and platform dependent emergency call system.


The TRIO personal alarm system device generates an alert when lone workers are in need of help.


SOS-Mobile App offers quick and secure alerting in an emergency. The application offers both deliberate and automatic emergency call functions and ensures quick assistance by automatically forwarding information about the person in need of help and their position to preferred end devices.


The SOS beacon allows indoor localisation in closed buildings in real time.

How important are your employees?

Employers are required to safeguard employees working alone by providing remote employee monitoring so that they receive help as quickly as possible in the event of an emergency. Swissphone’s web-based SOS emergency call system for lone workers monitors people working alone and automatically requests help in emergency situations, while also relaying the location of the injured person. Alerting scenarios and emergency plans stored in the SOS emergency call system are automatically activated to ensure assistance arrives as fast as possible.

A worthwhile investment

Invest in a sustainable, proven and SUVA-compliant SOS emergency call system – not just to secure your business, but also to demonstrate your appreciation of your workforce. Invest in a system which can safely and autonomously launch various risk and accident response scenarios.

Flexible and efficient operational handling

It’s essential to have a solution tailored to your business processes, and the Swissphone emergency call solution can offer you some decisive operational advantages. Controllers can manage device fleets themselves, and can also prepare and store company-specific alarm plans. Alerts can either be forwarded and escalated automatically, or processed manually – even by external service providers if required. When the designated rescue station receives an alarm, the system will indicate whether the event is a manually triggered alarm, a fall or loss of consciousness – and will also display localisation data and the appropriate alarm plan. Status information is constantly updated and displayed as further alert messages, and all alarms, status data and interactions are logged to assist subsequent analysis.

A dedicated personal emergency device or SOS app

Lone worker alerts can be triggered either by a TRIO (a small personal emergency device) or via the SOS app for Android and iOS devices. Lone worker alerts as well as alerts from routing systems or production facilities can be sent via both these lone worker safety devices. As well as operating via a web-based SOS portal, the SOS app also allows decentralised alarm processing. And its localisation option is another plus: The exact GPS position data coordinates are determined and sent to the Swissphone SOS portal via mobile radio technology alongside the emergency call message. Indoors, precise localisation to within one metre is provided by Bluetooth low energy transmitters, which are extremely quick and easy to install.

The legal background

Numerous organisations and institutions such as SUVA, DGUV, BG, etc. have drawn up regulations and recommendations which address the topic of lone working. According to this advice, a person is considered to be “working alone” if they cannot receive immediate help after an accident or in a critical situation. This can occur, for instance, when a working person is unable to have audio or visual contact with other workers. Rapid response and assistance is essential in lone working situations. Emergency call systems facilitate working alone in low- and medium-risk scenarios, and in exceptional circumstances they may also support working with critical hazards. However, in these instances a comprehensive risk assessment must always be carried out to comply with the regulations.

Maximum safety for lone workers on call

“As our work involves demanding processes as well
as complex building and plant structures with many
underground passageways, our employees’ safety takes
top priority. A reliable,safe and proven emergency call
system is therefore an absolute must for lone workers,”
says Werner Feurer, Director of ARA Chur. The underground
passageways of ARA Chur, some measuring up to 80 meters long,
and the complex plant structures result in high requirement
in terms of positioning and occupational safety of lone workers.
