Portable appliance testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use. Most electrical safety defects can be found by visual examination but some types of defect can only be found by testing
The Electricity at Work Regulations 1989 require that any electrical equipment that has the potential to cause injury is maintained in a safe condition. However, the Regulations do not specify what needs to be done, by whom or how frequently (ie they don’t make inspection or testing of electrical appliances a legal requirement, nor do they make it a legal requirement to undertake this annually).
There is no legal requirement to label equipment that has been inspected or tested, nor is there a requirement to keep records of these activities.
It is stated that the person doing testing work needs to be competent to do it
They will need:
The correct equipment to do the tests and ability to use this test equipment properly and understand the test results.
The law simply requires an employer to ensure that their electrical equipment is maintained in order to prevent danger. It does not say how this should be done or how often.
Some venues however may require proof this has been done before allowing a mobile disco to work at their venue to comply with their own insurance policy.
Like wise some Public Liability policies also require PAT testing as part of their policy too.
It is in the DJs interest to know that their equipment is safe both visually and electrically not only for safety but for reliability
Although the law does not state how often a test should be done, it is advisable to visually check cables for wear after every disco and check electrical connections, fuses etc every month with a full PAT test at least once a year.
If you prefer to test your own equipment consider a course that will show you how to test, what equipment you will need and how to interpret the results.(The person testing needs to be competent to do it)
