The potential harm from working with electricity primarily inflicts harm through thermal energy. When an electric current passes through a conductor, like human tissue, it can generate heat due to the resistance the tissue offers to the flow of the current. This heat can cause burns and other thermal injuries, which can be extremely severe depending on the magnitude of the current and the duration of exposure.

For instance, when electrical current flows through a person's body, it can heat the tissues sufficiently, leading to serious injuries or even fatal outcomes in some cases. This is especially relevant in situations where high voltage or high amperage is present, as the resulting thermal effects can lead to extensive damage to organs and tissues.

The other options, such as kinetic energy, chemical exposure, and radiation, do not primarily relate to the immediate effects of electrical shock or contact. Kinetic energy generally refers to movement and impacts, chemical exposure pertains to the reaction of substances, and radiation involves energy emitted in the form of waves or particles, none of which are the direct mechanisms of harm when it comes to electricity.
