In the past 25 years, the number of road traffic deaths has been drastically reduced, and the number of severely injured persons decreased significantly, too. Among others, the declining figures are due to improved passive safety. The use of high-tensile steel and composite materials adds to this.

The higher vehicle stability achieved by using these materials, however, becomes a problem in the event of an accident. Because the available rescue systems, such as power, plasma or hydraulic rescue cutters require a lot of time to cut the car body, or they even fail in individual cases. Time, however, is crucial during a rescue mission. The faster a person is freed, the higher the chances to survive.

This is where the project comes in: A compact laser unit shall be developed that can be used when conventional rescue tools reach their limits. With this system it shall be possible to cut modern materials in a short time, or to broach them so that they can be cut faster with conventional tools.

Moreover, it shall be investigated within the scope of the project how the safe use of the laser at the accident site can be guaranteed. Here, it is also being checked, for example, which shut-off devices are required for the system. In addition, the scientists evaluate which measures must be taken to protect the rescue team, the accident victim and uninvolved third parties. This includes curtains, mats and protection glasses.

The partners from many different sectors ensure that all relevant aspects are considered. Project partners of the LZH are: Coherent, SGE Spezialgeräteentwicklung, Weber-Hydraulik, Eifeler Lasertechnik, Laservision and the City of Dortmund’s Institute of Fire Service and Rescue Technology.

Associated project partners are: Bundesanstalt für Arbeitsschutz und -medizin, Berufsgenossenschaft Energie Textil Elektro Medienerzeugnisse, DB Fahrzeuginstandhaltung, Dekra Automobil, GuS – Präzision in Kunststoff, Glas und Optik, Bundesanstalt Technisches Hilfswerk, Unfallkasse NRW and Volkswagen. The project is being sponsored by the German Federal Ministry of Education and Research BMBF within the scope of the program “Civil safety – innovative rescue and safety systems” until October 2019.
