Forest fires are one of the main environmental problems facing the world today, consuming thousands of hectares of forest every year and directly influencing global warming due to the carbon dioxide (CO2) released in huge quantities by these fires, as well as being one of the biggest culprits in the destruction of natural animal habitats on the planet and, consequently, one of the biggest causes of species extinction. Over time, new technologies and procedures have been researched with a view to controlling forest fires and fighting them more efficiently, with less wear and tear on firefighters and less water consumption, given the increasing scarcity of this resource. As it becomes more difficult to obtain water and the intensity of the fire increases, the need arises to use chemical products that improve the efficiency of water in extinguishing the fire or that can replace it. The aim of this work was to optimise the Standard Operating Procedure (SOP) for fighting fire in vegetation using chemical flame retardants, with a view to saving water resources.
