There are many common myths about portable appliance testing (PAT) - find out the key facts about the inspection and testing of portable electrical equipment here.
What is portable appliance testing?
1.VISITING CLIENTS PREMISES |
|
HAZARDS |
PRECAUTIONS /PROCEDURES |
Clients: Work activities/processes Location |
Fill in the visitors book at reception Comply with the clients procedures/rules for contractors:
Site induction Access and egress requirements Fire and evacuation Personal protective equipment Prohibited areas |
2.PORTABLE APPLIANCE TESTING |
|
HAZARDS |
PRECAUTIONS /PROCEDURES |
Contact with livecables/surfaces Electrocution Electric shock Burns Fire Property damag Equipment damage |
All electrical work must be carried out by a trained and competent person.
Follow written electrical test procedures.
Use correct testing quipment.
Isolate and disconnect from mains. |
3. LIGHTING |
|
HAZARD |
PRECAUTIONS/PROCEDURES |
Low levels of lighting Slips, trips and falls (resulting in serious injury) |
No work is to be carried out without adequate lighting: Ensure that the lighting levels are adequate to enable the inspection and test to be carried out safely. Where necessary obtain and use110v portable task lighting. |
4. HAZARDOUS SUBSTANCES/MATERIALS | |
HAZARDS | PRECAUTIONS/PROCEDURES |
Exposure to toxic, harmful, irritant or corrosive ubstances causing acute and/or chronic ill health Fire and/explosion |
Comply with the clients procedures/rules for contractors Adhere to information, mandatory and/or warning signs Keep out of all hazardous areas |
5. CONFINEDSPACE/AREA |
|
HAZARDS |
PRECAUTIONS/PROCEDURES |
Excess and/or lack of oxygen Toxic gases/vapours Fire and/explosion Engulfment Slips trips and falls |
Avoid entry wherever possible. Do not enter a confined space unless trained to do so and then: Comply with the clients procedures /rules for contractors Devise a safe system of work Comply with permit-to-work procedures where applicable Use intrinsically safe equipment when required and available Adhere to information, mandatory and/or warning signs |
6. MANUAL HANDLING |
|
HAZARDS |
PRECAUTIONS/PROCEDURES |
Muscular skeletal disorders Strains/pulled muscles and ligaments Backinjuries Cuts and bruises |
Avoid, assess, reduce Avoid, use mechanical means if at all possible Assess,the weight, reduce into smaller packages/loads Decide if one or two persons are required for the lift Use kinetic handling techniques Wear the correct personal protective equipment |
Site Approach
Upon arrival on site our test engineer will introduce himself to the client’s representative and explain the purpose and nature of the work to be carried out. This person will then be asked to accompany our engineer around the site to highlight any sensitive areas and introduce the IT manager who should confirm any arrangements that have been made for shutting down any IT workstations.
Standards
The inspection and testing shall be carried out in accordance with the requirements of the following regulations and publications:
Electricity at Work Regulations 1989
Health & Safety at Work Act of 1974
IEE Code of Practice for the in service inspection and Testing of Portable Electrical Equipment
Identification of equipment
Every piece of electrical equipment will be allocated a Asset ID / number. This will be used to cross reference test results to the certificate supplied. A register of equipment will then be produced to include the following details:
Asset number
Location in which the appliance/asset is kept/used
Description of appliance
PASS / FAIL result for tests completed
Date of test
Testing Procedures as stated by the IEE Code of Practice for In service Inspection and
Testing or Portable Electrical Equipment.
Visual Inspection
A visual inspection of the appliance shall be carried out prior to any testing. The inspection includes the following:
Socket Outlet is there any evidence of overheating, cracks or damage?
Plug is the flexible cable secure, are the pins insulated, is it free from cracks, or damage and signs of overheating?
Flex is in good condition, free from cuts, fraying or damage?
Appliance does it work? . Is it free from damage? . Can it be used safely?
In addition, the visual inspection will check that the means of disconnection from the mains supply is also readily accessible and that wherever possible, flexible cords are positioned so that they do not present a hazard.
All minor faults identified during the visual inspection, such as incorrectly rated fuses, damaged 13amp plugs, loose connections will be rectified prior to the testing procedure.
Testing
Subject to a satisfactory visual inspection, the following sequences of test are carried out.
Earth continuity – Class 1 appliances only
Insulation resistance (where appropriate)
Operation/load test
Earth leakage test
Labelling
A sample of the labels we use is shown here. Any FAILED appliances are taken out of service and are
immediately brought to the attention of the client representative on site.
Report
Upon completion a report is produced usually within 5 working days listing the appliances tested, the results of the tests performed, and details of any remedial repairs necessary. We also provide the engineers observations on all failed equipment.
