Portable Appliance Testing is a process by which your equipment is routinely inspected and tested to see if it is safe. Every year, about 30 people die from coming into contact with electricity, and many more are injured. About a quarter these accidents involve portable appliances. By testing items of electrical equipment, we should be able to spot faults before they have a chance to harm anyone, the interval between tests depending on both the type of appliance and the environment it is used in.
