Portable Appliance Inspection and Testing or PAT Testing, as it is sometimes referred to, is an important part of any health and safety policy. Since the 1st April 1990 it has been a legal requirement for employers and the self employed to have all portable electrical appliances and equipment periodically inspected and tested for compliance with the safety regulations. This means that all portable appliances need to be subjected to electrical testing.
Current legislation demands that employers ensure portable appliances are safe. The predominant relevant regulations include:
Regulation 3 of the Electricity at Work Regulations specifies that employers and the self-employed are liable for the correct use and maintenance of all portable appliances at their place of work. Employers in this context include those people accountable for the management of offices, factories, shops, hospitals, universities, hotels and all other building used by the public.
A portable electrical appliance is defined as any electrical equipment that is powered between 40 and 240 volts and which is connected to the electrical mains via a flexible cable / plug and socket (usually a 13 amp outlet). It does not imply that the appliance is readily portable, only that it can be moved without unwiring. Portable electrical appliances owned by employees are occasionally brought to and used in the workplace. This policy applies to such appliances as if they were the property of the business.
Portable appliances are not just pieces of electrical equipment that require testing routinely. They include everyday appliances such as:
David Sykes Electrical always use a qualified electrician, who has the knowledge and practical experience of electricity and its hazards, to carry out both visual and electrical testing. Since the person must make judgements on the appropriate level of electrical appliance testing required, they must understand the operating principles of each portable appliance and have adequate knowledge of the relevant safety standards.
The Portable Appliance Testing that David Sykes Electrical offers is very extensive and covers appliance testing in all work environments. The tests fall into two categories:
Visual Inspection
This is the most important element of portable appliance
testing as over 80% of potential hazards are detected
by physical inspection. The qualified electrician will
be looking for hazards such as damage to the insulation
of the appliance or the mains lead, incorrect wiring
or fuse rating of the mains plug, unsafe cable joints,
loose connections and accessible live conductors.
Electrical Testing
The type of electrical testing performed on portable
appliances depends on the safety design itself. Class
I portable appliances are the most common type. It relies
on earthing of its conductive case and one layer of
insulation covering its live internal parts for its
prevention against electric shock.
Class II appliances have no earth connection and rely on two layers of insulation that cover the live parts as protection to the user. Usually the second layer of insulation is the case of the appliance itself. All Class II equipment is physically inspected as a satisfactory test of Class II appliance safety.
The electrical tests carried out using the latest PAT equipment on each appliance includes:
Labelling
All equipment that is inspected and / or tested
will be provided with a label that will include an identification
code to enable the equipment to be uniquely identifiable
even if several items exist within the same premises.
An indication of whether the item has passed or failed
the appropriate safety inspection and/or test will be
included. The date on which re-testing is due or the
last test date and re-test period will also be stated.
Records
David Sykes Electrical keep full records of each
piece of equipment with its unique number and full description
for future traceability. A full Status Report
will be sent to the client indicating what equipment
has passed or failed and when it is due for re-testing.
Should we locate any failures we can avoid extra work
by carrying out minor repairs as we find them such as
replacing a plug, fuse or cable repairs.
The client will be notified of any items that fail the test and cannot be mended by a minor repair. Equipment found to be unsafe would be removed from site by the client or by David Sykes Electrical, as agreed. Any items requiring major repairs will always be quoted first. These repairable items will then be repaired on site or can be returned to our central workshop. Following a major repair we will issue a Re-test Certificate Following Repair Report.
