Fire has been a protagonist of human history; from the first prehistoric fireplaces, born about 400 thousand years ago, to the flames of space rockets, it has always accompanied man in his daily life and in his undertakings. The episode also illustrates, above all, the risks that fire entails: fires, burns, explosions. And he will explain what are the best ways to fight it. In the house, in the car, wherever the flames develop. Alberto Angela travels to various places where fire is the protagonist, also following the special fire departments in their interventions and demonstrations. We will see spectacular images of fires and men intent on putting them out. We will talk about the chemistry of fire, the mistakes to avoid, and how to behave in an emergency. Many people, for example, have died trapped in the car due to failure to provide assistance: the fear that the tank will explode keeps many people from providing help when the car catches fire.
