Limit the exposure

Have live parts exposed for as little time as necessary. This does not mean that you should work hastily. Be organized so that the job can be done efficiently. Provide a means to switch off any equipment if someone should somehow be trapped by moving parts or receive an electrical shock. For large items of machinery this will usually be in the form of an emergency stop button. For simpler equipment it will be a plug and socket (just unplug to switch off) or a local switch. This should be accessible. Having the socket for a washing machine or a fridge hidden behind the machine is no use in an emergency move the socket to the side or provide a switch where you can get at it which feeds the hidden socket.
