Portable appliance Testing

Electrical testingWith a new code of practice issued this year, you could save considerably on your Portable Appliance Testing (PAT).

Instead of testing all equipment every 12 months, the new guide requires a regime of testing and inspection, based on risk based assessments.

The risk assessment is the responsibility of the duty holder, e.g. facility manager, building manager, landlord etc. We can assist with this process.

The risk is based on the type of environment the equipment is used in, as well as the equipment itself.

The relevant provision of the Electricity at Work Regulations 1989 is Regulation 4(2) which states:

As may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practicable, such danger. Inspection and testing are means of determining whether maintenance is required. Frequency of inspection and testing will depend upon the likelihood of maintenance being required and the consequence of lack of maintenance. To reflect accurately the legal requirements of Electricity at Work Regulations 4(2), a robust risk assessment should be carried out in all cases, to evaluate the frequencies between inspection and testing. Risk encompasses many factors that can eventually influence a final decision and should include the following:

  1. The environment
  2. The users
  3. The equipment construction
  4. The equipment type
  5. The frequency of use
  6. The type of installation methods (particularly fixed equipment)
  7. Previous records
