Defibrillators are devices that use a large jolt of energy to reset the heart during episodes of sudden cardiac arrest.

Electricity is extremely dangerous so you need to focus on safety at all times when dealing with it. There are special gloves just for the purpose.
Electrical gloves are used to protect the electrician from accidental contact with charged systems while working. In normal situations, electrical systems are deactivated before work is performed. It is normal to shut down the entire electrical supply to a work area and most often equipment is even tagged out to insure that no one turns it back on. There are occasions when the electrician must work close to a charged system. At these times, protective gloves can be a life saver.
