Bare electric wires have a high chance of creating a short circuit, which can cause serious damage and start fires. A person can also easily get electrocuted if the wire comes in contact with the person which can be fatal. Bare electric wires are dangerous because of the higher risks of shock or electrocution.
Are insulated wires dangerous?
Cloth wiring is considered dangerous because the cloth insulation around these wires can become brittle and deteriorate overtime. As the insulation around these wires deteriorates, there is a higher risk of a fire developing. Most issues occur with the early forms of this wiring.
