This final paper are processed all possible causes of fires and explosions that, in practice, very often realized under the influence of the effects of various possible types of sufficiently strong sources of electricity. They are described in more detail basic features of the most common types of dangerous pathogens fire and explosion electrical nature, their ability to cause inflammation possibly present type of combustibles and creating a fire or explosion, along with explanations of how they can be reliably avoided professional and investigative prove. To illustrate the scale of the problem presented to the relevant domestic and international statistical data on fires and explosions caused by electricity, and then the many, often-noted gaps prevention of which should be competently managed much more care in order to achieve a satisfactory level of security and fire protection the explosion and, thus, significantly reduce the number of fires and explosions caused by electricity and avoid possible serious consequences so caused generally dangerous events. Therefore, the work presented and the corresponding current legislation laying down the conditions of construction of buildings and installation of electrical equipment and installations in order to avoid the possibility of fire or explosion. In the final part of the paper is the current used methods and techniques expertise cause a fire or explosion electrical nature within the structures of buildings and vehicles.
