Check the electrical supply is safe to use

You should be sure that the electrical supply is safe to use. Regular tests performed by a competent person, using suitable equipment are a good way of reducing risks. Where there is evidence that the supply may not be safe, such as damaged equipment or wiring, the supply should not be used until work has been done to correct this. Some simple user checks can be carried out on electrical socket outlets using an electrical socket tester, but it is essential that the correct type of tester is used . If any doubt remains regarding the safety of the electrical supply, a competent person should be consulted.
