This will need to be backed up by testing as necessary. It is recommended that fixed installations are inspected and tested periodically by a competent person. The frequency of inspections and any necessary testing will depend on the type of equipment, how often it is used, and the environment in which it is used. Records of the results of inspection and testing can be useful in assessing the effectiveness of the system. Equipment users can help by reporting any damage or defects they find.
Work safely Make sure that people who are working with electricity are competent to do the job.
Even simple tasks such as wiring a plug can lead to danger - ensure that people know what they are doing before they start. More complicated tasks, such as equipment repairs or alterations to an electrical installation, should only be tackled by people with a knowledge of the risks and the precautions needed. You must not allow work on or near exposed live parts of equipment unless it is absolutely unavoidable and suitable precautions have been taken to prevent injury, both to the workers and to anyone else who may be in the area. Underground power cables Always assume cables will be present when digging in the street, pavement or near buildings. Service plans should be available from regional electricity companies, local authorities, highways authorities, etc.
