A toaster in a bathtub can be an extremely dangerous combination, potentially leading to electrocution and death. The reason behind this lethal danger is the presence of water, which is an excellent conductor of electricity.
When the toaster is immersed in water (like a bathtub full of water), it creates a pathway for electricity to flow from the electrical outlet, through the toaster, and into the water. Water allows the electric current to pass through easily, and since our bodies are also conductive (to a certain extent), if a person is in the water and touches the energized water, the electricity will flow through their body as well.
Electricity takes the path of least resistance, so it will pass through the human body, seeking a way to return to the electrical source (in this case, the electrical outlet). When electricity flows through the body, it can disrupt the normal electrical signals that control our muscles and nerves, leading to muscle contractions, burns, and potentially fatal heart irregularities like ventricular fibrillation, which can cause the heart to stop beating effectively.
This is why it's absolutely crucial to avoid any electrical appliances or devices, like toasters, hair dryers, or radios, near water sources such as bathtubs, sinks, or swimming pools. It is a hazardous combination that can lead to serious injury or death. To prevent such accidents, always ensure that electrical appliances are kept away from water sources and never handle electrical devices with wet hands. Additionally, make sure to have Ground Fault Circuit Interrupter (GFCI) outlets installed in areas where water is present, as they can quickly detect and cut off power in case of an electrical fault, reducing the risk of electrocution.
