Main professional training is often supplemented by individual specialist courses. Volunteer crews pursue civilian occupations and the training must be completed during the off-peak times or in other free periods. Another criterion on fire department training classes covers various certifications and quality management. This is necessary to allow individual members the same functions based on equal education. In times of limited financial resources, it is also necessary to organize the training as effectively as possible.
Euro emergency 112 has prevailed more or less in the context of EU states. The emergency number was also introduced in new member states. A firefighting organization can be formed by the community, a private company working on behalf of a municipality or a branch of service of the military. Structures of these establishments differ depending on population structure and density.
In many countries, there are fire departments that specifically cater for the recruitment of young people. In some countries, there is a worrying trend of declining number of volunteer emergency services enrollments in fire departments. This necessitates heavy advertising campaigns to attract new members.
The above determines the amount of water needed to make the atmosphere inert, to prevent the pyrolysis gases to burn. When the right water volume is used for cooling the fumes, the atmosphere is covered by the thermal approach. This approach still has some limitations. Thus, spray nozzles do not allow complete evaporation of water supplied. The efficiency is determined by a function of the nozzle but also firefighter skills. Different methods of calculations take into account these parameters.
Training for firefighters depends on the structure of relevant departments in each state. The training is more centrally arranged in fire services or decentralized into various sections. There are different training courses for professional and volunteer firefighters. The departments are indirectly tasked with the prevention of environmental damage.
Extinguishing fires entails a combination of suffocation by steam and cooling. A common idea is that cooling off is a priority when fighting blazes. It is easy to prove otherwise by cracking a match and putting it over a pan of boiling water. The match burns in cold air but goes off in the hot steam. There is two types of flame: the diffusion flame that dances over a burning object and the premixed flame, which propagates in smoke.
In the case of diffusion of a flame, the limiting factor is the supply of oxygen (assuming that fuel is abundant). The flame itself provides heat and hence choking steam is the most important. Conversely, with smoke, the fuel and oxidizer are already mixed and steam does not hunt the oxidant but simply dilute the mixture. Temperature is a critical factor when it comes to the spread of premixed flames, cooling makes it possible to significantly reduce the fire\’s magnitude, thus a cooling and dilution combination is necessary.
Fire protection receives more attention in industrialized nations, whether through their own private entities or public departments. In addition, these organizations are frequently consulted as part of official building permit approvals involving larger construction projects. Furthermore, they are involved in various disciplines in the creation of safety standards. In addition, the brigades operate active environmental protection, such as the containment of oil spills, eliminating traces of oil on roads and protection against chemical, biological and nuclear hazards.
