Question:
How often should I carry out PAT Testing?
Answer:
The underlying principle for frequency of testing is that the duty holder (i.e. the person with the equipment "within his control") with the advice of the competent test person when necessary must assess the need for testing the equipment against the following factors:
Type of equipment (portable, hand held, moveable, sationary, IT or fixed)
Style of use (continuous, infrequent, rough)
Age of the equipment
If regularly moved or transported and by what means
Type and competence of personnel using the equipment
Environment of usage (outdoors, construction sites, hazardous atmospheres etc).
Results of previous tests
Manufacturer's recommendations
Effect of any modifications or repairs to the equipment
The equipment construction ie. Class I earthed or Class II double insulated.
By carrying out a risk assessment using the factors above then a final decision can be made on the frequency of tests or inspections required. For example, a power tool used on a construction site should be examined more frequently than a computer in a office.
