1) Which of the following is not a category of electrical burns? a) Electrical b) Arc flash c) Shock d) Thermal contact

While electrical burns can be categorized into various types based on their sources, "shock" primarily describes the physiological response to an electric current rather than a distinct category of burns. When someone experiences electrical shock, it can be accompanied by burns but it's more about the effects on the body rather than the burn itself. Understanding the different types of electrical burns helps in both prevention and treatment. For instance, thermal contact burns occur when a person touches an electrically heated object, emphasizing the importance of safety measures around high-voltage environments.
