As we age, fewer hairs grow, fine hair increases and coarse hair decreases. Hair diameter, density and breaking strength decrease. When the human body comes in contact with electricity, current passes through it, causing shock. The amount of current and the length of contact can cause minor pain, serious injury or even death. Never poke metal objects like knives into appliances such as toasters.
Shock can occur.
Shock can also happen when current makes contact with water, such as when a plugged in hair dryer falls into bath water. Appliances should not be left near bathtubs, sinks or pools. Don't touch live wires with your bare hands or you will be shocked too. Use a thick, dry object, such as a stick or rolled up magazine, if you must try to pull the person away and can't remove the source of current. Call for help right away.
