New laser rescue system for serious accidents

2017-05-09

Better technologies increase the traffic safety and save human life. But they pose totally new challenges for the emergency personnel at the accident site. Because often, tools like hydraulic rescue cutters more and more reach their limits today. A mobile laser unit for rescue missions shall solve this problem. With this system it shall be possible to cut modern materials in a short time.

The chances for rescue are much higher the faster a person can be freed from the vehicle.

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.
