PAT stands for Portable Appliance Testing. It is a routine inspection conducted on electrical appliances and equipment to make sure they can be used safely in the workplace and any other public environment.
PAT usually involves visual and electrical inspections. The visual test searches for visible signs of damage, such as cracks, dents, discolorations, scorch marks, and wear. Electrical inspection utilizes specialized PAT devices to detect some types of defects. The procedure includes earth resistance, earth continuity, and insulation resistance tests, as well as polarity and safety-switch checks.
The Health and Safety at Work Act 1974 states that employers are responsible for the safety and well-being of their employees in the workplace. Businesses are also accountable for any customer or visitor who might be on the site.
Furthermore, the Electricity at Work Regulations 1989 requires all companies to inspect their electrical appliances and equipment regularly to ensure that they are safe to use. Failure to comply with the legislation can lead to severe penalties.
