1 . There's a loud bang, and then it starts: A battery of an electric car is on fire in the test tunnel. A video of the test impressively shows the energy stored in such batteries: meter-long flames flee in disorder and produce enormous amounts of thick, black smoke. The visibility in the previously brightly lit tunnel section quickly approaches zero. After a few minutes, ashes have spread throughout the room.

And the operators ask themselves: “

E.But in the three tests in the tunnel the concentrations remained far below critical levels |
F.What will happen if such a car catches fire |
2 . Traffic Regulation and Accident Prevention
We live in a remarkable time, and many of the once fatal diseases can now be cured with modern medicine and surgery. It is almost certain that one day a cure will be found for the rest of the diseases. Expectations of life have greatly increased.
