The SOS lone worker protection solution with the components SOS-Portal and SOS-Mobile App has been re-certified for selected Android devices according to DIN VDE V 0825, which is one of the most respected global standards.

«We are proud of the DIN VDE V 0825 certification of our emergency call solution in combination with the latest generation of i.safe MOBILE smartphones. i.safe MOBILE is a market leader for explosion-proof mobile phones. In combination with our SOS Mobile App and the SOS Portal, it provides the highest possible level of safety for lone workers», says Thomas Knoblauch, Product Manager Swissphone Wireless AG. With this certification, Swissphone and its partner i.safe underline their ambitions in the area of lone workers: according to studies, the number of employees working alone is expected to continue to grow. This is because companies will strive even more for efficiency in the future. «The possibilities of digitization allow the qualified personnel to be more and more independent in production plants. In addition, personnel resources are allocated more and more efficiently, resulting in 'working alone'. Exactly this personnel needs protection in case of an emergency! Ideally on smartphones, which are already used in the course of daily work anyway. This is what the partnership between Swissphone and i.safe MOBILE stands for, to provide a personal emergency call system. In accordance with DGUV rule 112-139 (formerly BGR 139)», explains Markus Thomas, Sales Manager at i.safe MOBILE GmbH.

Employers are obliged to safeguard lone working employees so that they can receive help as quickly as possible in the event of an emergency. To ensure this, Swissphone's web-based SOS emergency call system for lone employees is the ideal solution: It monitors people working alone and - depending on the situation - helps initiate an emergency call either manually or automatically. This is done by means of the programmable alarm button or by means of the sensor technology built into the smartphone, which detects accidents. The position of the person involved in the accident is transmitted, indoor via BLE-beacon, outdoor via GPS. The alarm scenarios and emergency plans stored in the SOS emergency call system are activated automatically and guarantee the fastest possible assistance. The basis for this is the web-based SOS-Portal, which controls the reporting, localisation, escalation and complete documentation of incidents and manages the users.

Regardless of lone worker device, the emergency solution offers the following protection functions:

  • Fast and safe alerting in case of emergency by means of manual and automatic emergency call triggering functions. Automatic forwarding of the emergency call via several channels with information on the person concerned and their position.
  • Decentralized receipt of incoming alarms and their processing according to an individual alarm plan. If the emergency call is not accepted, the call for help can be escalated until suitable measures are taken.
