Use the following devices to ensure the safety of the safe use of electricity. Fuses, miniature circuit breakers or MCBs, earthwires, three pin plugs, earth leakage circuit breakers or ELCBs. To prevent electric shocks and short circuiting, here are some of the safety measures we can take. One, don't poke anything into electric sockets. Two, don't touch electrical appliances or sockets when your hands are wet. Water can conduct electricity. Three, don't use appliances with damaged or exposed wires. Four, don't overload a power socket by plugging too many appliances into it. This will draw a large current which may burn the wire and cause fires. Be particularly careful about this since many of us like to connect multiple appliances to one socket. Five, don't change a bulb until you have turned off its switch. Six, don't try to repair an electrical appliance by yourself. Get an electrician to do it.
