This section GB/T 13870 describes the impact and effect of natural electricity generated in the form of lightning strikes during thunderstorms. Lightning current may be It consists of several unipolar and/or bipolar pulsed currents with different current peaks and periods. While in GB/T 13870.2-2016 [24] Chapter 6 does not include this effect. The interaction between a lightning strike and the victim's body is completely different from the conventional test results from the shock current of the electrical system. Lightning strike In an accident, the current path often includes the header. The importance of the lightning current entering through the cranial orifices is pointed out and by this path approaches the brain dry. The brainstem contains the respiratory center, and the lightning current flows in the opposite direction from the electric shock current generated by the electrical system. In particular, it should be noted that by the cross There is a difference between the step-voltage induced interaction and the accident caused by the direct lightning. Even lightning a very short single pulse, Can cause heart-lungs to stop working [5], [6], [12], [13]. It is very dangerous to apply strong electricity to living organisms, however, it is surprising that, in most cases, it is not always fatal. people The accepted fact is that more than 90% of people involved in a lightning strike are not fatal (see references [1] and [12]). Corresponding to livestock The reliable data is unknown. For accidents that occur, due to different environments, people's initiative and first aid knowledge and medical care quality The difference, the result is also very different [1], [5]. Therefore, in the light of the special effects of lightning, a separate document needs to be developed. The physical process of lightning strikes is taken as the basis. The phase of the organism Interactions and the dangers to the life of living organisms are explained in the following clauses. Effect of current on humans and livestock Part 4. Lightning effect1 Scope and purposeThis section GB/T 13870 is a technical report that outlines the basic parameters and their variability of lightning and human effects on livestock. This section points out the direct and indirect interactions that lightning can have on living organisms. Also describes the lightning current through the creature Body caused by the effect. The purpose of this section is to show the difference between the effects of lightning strikes on humans and domestic animals and the effects of electric shocks from electrical systems.2 Normative referencesThe following documents for the application of this document is essential.
