Action in occupational safety . (this as we know, is one of the specialties of the prl). The reasons are obvious: fires are a universal risk. They also have enormous intrinsic potential to cause damage to people and material goods. Fire prevention techniques in project planning actions aimed at fire prevention techniques must begin to be adopted in the same phase of planning and execution of any work or installation project. For these cases, consultation and application of the technical building code (cte) is essential . Specifically, what is established in the basic document of security in case of fire (db-si) of the cte must be applied. In the db-si, the obligatory
guidelines for development are established, aimed at avoiding internal (si-1) or external (si-2) propagation. We also find issues related to the evacuation of occupants (si-·3). These documents develop such important issues as the compartmentalization in e commerce photo editing fire sectors or the cataloging of special risk zones. In addition to these, the db-si also has the so-called da (support documents) . These documents establish the testing and classification standards for fire resistant doors or building exits and the design of a safe outdoor space. But, once the building, the facilities and the workplace have been built, even following the strict guidelines established by the cte, the risk of fire is
still present in any workplace. The three most frequent causes of fire in orp it is important to know the cause and origin of the risks in order to combat them in the most effective way. Research in this regard has established that 45% of the fires that occur each year in workplaces in our country have their origin in the following three sources of ignition: fires with electrical origin 19%. The factor with the highest percentage of responsibility in the origin of fires is electricity. Fires of electrical origin are caused by failures and short circuits in electrical installations or devices. Failures and overloads of electrical installations cause a considerable rise in
