Portable Appliance Testing – The Visual Inspection
Visual inspections are carried out as part of the PAT Test and should only be carried out by persons competent to do so. The results of the inspection must be documented.
When conducting the visual test portion of the PAT Test the following must be considered
Suitability of the equipment and environment
The suitability of the equipment within the environment where the equipment is being operated need to be assessed. The frequency of testing and nature of the PAT test needs to be assessed according to the harshness of the environment.
Due Diligence
An assessment has to be made as to whether the equipment is installed and operated in accordance with the manufacturers instructions. In addition to the manufacturers instructions, the following are examples of items which should be checked:
- Cables located to avoid damage and risk of damage
- Means to disconnect and isolate must be easily accessible
- Adequate ventilation
- All sources of water – direct and indirect such as plants, taps etc. to be kept at a safe distance to avoid spills
- Power cords and leads are not to be put under strain
- Any appropriate covers and doors are secured when items are being operated
- Indiscriminate use of multi-way adaptors, extension leads and trailing sockets
- No unprotected cables run under carpets
Disconnection of the appliance
The source of the electrical supply and isolation must be readily accessible to the user – the plug and socket must be easily accesible.
