Is PAT Testing A Legal Requirement?

Is PAT Testing A Legal Requirement?

by

“Is PAT Testing a legal requirement?” is probably in the top ten of our most frequently asked questions.  In this article we answer this question and explain how do decide if and when you need to do PAT testing.

PAT testing can be used to demonstrate that an employer is carrying out a preventative maintenance regime on electrical equipment, but it is not a legal requirement. In fact, the HSE themselves reviewed their own PAT testing policy in 2011 and decided that some of their electrical equipment did not need testing at all!

This doesn’t mean you can just cancel all further PAT testing!

You should only do that if you carry out a risk assessment to justify it. You need to look at the type portable electrical equipment your company uses, understand how it is used and the environment it is used in before deciding upon inspection and testing regimes.

Understanding PAT testing?

Portable appliance testing (PAT) is the term used to describe the examination of electrical appliances and equipment to ensure they are safe to use. A full PAT test should include both a visual inspection and a more in-depth check using specialist PAT testing equipment.  This test includes earth continuity, lead polarity, and insulation resistance checks.

The limitation of PAT testing is that it is only valid at the time it is carried out. For example, a power drill could be tested in the morning and in the afternoon an employee takes it out to use, drops and damages it internally. The plug will still have a sticker on it to say that the PAT testing is in date, yet the tool is damaged. If the employee returns the tool and does not tell anyone that it has been damaged, someone else could use a defective piece of equipment. It is therefore important that PAT testing is used as part of a wider inspection and testing and defect reporting regime.

Using PAT testing as part of an inspection and testing plan

There are 3 main criteria which determine frequency of testing:

  • the risk level of the working environment
  • the electrical class of the appliance
  • the category of the appliance

For example, the HSE reviewed their office PAT testing regime because a lot of their electrical equipment included items such as desk top computers which, although they are class 1, are used in a low risk environment and are not moved. The conclusion was that these items were low risk, therefore this increases the interval for PAT testing when combined with visual user checks. A wall mounted television used for displaying information will not require PAT testing at all as it is class 2 (safer than class 1) and is never used.

Conversely a portable power tool that is used in dusty environments and is regularly transported between construction sites in the back of a van should be PAT tested more regularly, say every six months.
