Portable Appliance Testing (PAT)

• Visually inspect every portable appliance before each use for obvious defects.
• Check the plug, cable, casing, and on/off switch are all in good condition.
• Ensure all site equipment has a current PAT test label before using it.
• Remove defective equipment from service immediately and label it as faulty.
• Report damaged cables, cracked casings, or loose connections to the supervisor.
• Arrange formal PAT testing at least every 3 months for 110V site equipment.
• Keep a register of all portable appliances and their PAT test dates on site.
• Use 110V supply from a centre-tapped transformer for all portable site tools.
• Return hired equipment that arrives on site without a valid PAT test label.
• Train users to carry out basic visual inspections before each use.

• DON'T use any portable equipment that does not have a current PAT label.
• DON'T continue using a tool with a damaged cable, cracked plug, or loose wires.
• DON'T attempt to repair damaged cables or plugs unless you are a competent person.
• DON'T remove the PAT test label from equipment or alter the test dates.
• DON'T bypass the 110V transformer to connect tools directly to 230V mains supply.
• DON'T assume equipment is safe because it was working fine yesterday.
• DON'T ignore scorch marks, burning smells, or excessive heat from equipment.
• DON'T put defective equipment back into the tool store without labelling it faulty.
• DON'T rely solely on PAT testing; user visual checks are equally important.
• DON'T use extension leads that are coiled up; unwind them fully to prevent overheating.
