What is Portable Appliance Testing (PAT)?
Portable Appliance Testing, or PAT, refers to the process of inspecting and testing electrical appliances and equipment to confirm they are safe for use. Many electrical safety issues can be identified through a visual inspection, though certain defects are only detectable through testing. It’s important to note that visual checks are a crucial component of PAT, as some faults may be visible but not detectable with testing equipment alone.
A basic user check, supported by simple training and a checklist, can be an effective part of an electrical maintenance routine. However, regular visual inspections and testing by a qualified person may also be necessary at specific intervals, based on the type of equipment and its operating environment.
How often should Portable Appliance Testing (PAT) be conducted?
PAT testing is not legally required, but the Electricity at Work Regulations 1989 mandate that electrical equipment capable of causing harm must be maintained in a safe condition. This does not mean that inspections or testing are compulsory or that they need to be done annually.
The recommended frequency of PAT testing depends on the nature of the equipment and its setting. For instance, a power tool on a construction site should be tested more frequently than a bedside lamp in a hotel room.
For specific recommendations on testing intervals, see the guidance provided by the Health and Safety Executive (HSE).
