Up until that time, there have been documented cases of people accidentally dropping electrical appliances, including toasters, into bathtubs, resulting in fatalities. However, I don't have access to statistics on how many such incidents have occurred or whether there has been a single specific documented case that gained widespread attention.
It is essential to remember that water and electricity do not mix and can be a deadly combination. Therefore, it's crucial to exercise caution and follow safety guidelines when using electrical appliances near water sources like bathtubs or sinks. Always ensure that electrical appliances are kept away from water and never handle them with wet hands or while immersed in water.
