Why is is advised to avoid use of hair dryer and an iron with wet hands?

It is advised to avoid using a hair dryer or an iron with wet hands due to the risk of electric shock. Water is a good conductor of electricity, and if either device comes into contact with moisture, it can create a path for electricity to flow through your body. This poses a serious safety hazard, potentially leading to severe injury or even fatality. To ensure safety, it's best to dry your hands thoroughly before using such appliances.
