Abstract
Dangerous situations connected with fire can be created in daily life and they can have serious consequences without a basic scientific information. Not knowing what to do in these cases and being unfamiliar with the adequate use of each fire extinguisher, may provoke that a small fire becomes a huge one. In consequence, the best safety measure is the knowledge of the different chemical agents´ properties. With this purpose, experiences of their properties as well as their behaviours against different types of fires are shown.
