this latter may kill him. Fires in electrical equipments are caused by overheating or sparking. They can also be caused by damaged insulation. The main danger of most small fires is that they can spread quickly. All electric tools, equipments and other installations should be earthed, especially if they are made of metal. An earth- wire has a very low resistance. If electricity “escapes”, it follows the earth-wire. The equipment is still safe to touch. All electrical wires should also be insulated. Insulation prevents contact between the electric circuit and anything else. The insulation must not be broken or frayed. In addition, electricians and other workers doing electrical repairs should take special precautions: before starting work, they should switch off the electric current at the mains and wear thick rubber shoes -rubber has high resistance to electric current.
