Portable appliance testing (PAT)
A portable appliance is generally defined as any electrical equipment that is not part of a permanent installation but is instead connected to a power supply via a plug and socket. It can be easily moved from one place to another and can be easily transported. Examples of portable appliances include kettles, toasters, desktop computers, fans, electric drills, vacuum cleaners, and floor polishers.
The frequency of PAT testing depends on the level of risk and the type of equipment and environment. For example, a heavily used drill in the construction industry is high risk and should be tested more frequently, while a freezer in a kitchen is low risk and may not need annual testing. In the UK, there is no legal requirement to undertake PAT testing, but it is recommended to ensure the safety of electrical equipment and to comply with health and safety regulations.
PAT testing is typically carried out by qualified professionals who use specialized equipment to check for potential electrical hazards. They look for various safety issues such as proper insulation, correct earthing, and correct fuse ratings. If any issues are found, the equipment is labelled as "failed" and must be repaired or replaced before use.
Regular PAT testing is essential for businesses and organizations to maintain electrical safety and comply with insurance requirements. It is also important for landlords to ensure the safety of electrical appliances in their rental properties. While visual inspections and user checks are a good method of maintaining portable electric equipment, formal inspections and testing by competent persons may be required at appropriate intervals.

Health and safety regulations
The Occupational Safety and Health Administration (OSHA) is the federal agency responsible for setting and enforcing these standards. Under OSHA regulations, employers are responsible for providing a safe working environment for their employees, which includes ensuring that electrical equipment and portable appliances are safe and do not pose a hazard.
One of the key health and safety regulations related to portable appliances is the requirement for regular inspection and testing. This is often referred to as Portable Appliance Testing (PAT). While PAT is not a legal requirement in the USA, it is strongly recommended as a best practice to ensure electrical safety. PAT involves the examination of electrical appliances to ensure they are in safe working condition and do not pose a risk of electrical faults, fires, or injuries.
The frequency of PAT testing depends on the type of equipment and the environment in which it is used. For example, a power tool used on a construction site would typically be examined more frequently than a lamp in a hotel room. Additionally, the National Fire Protection Association (NFPA) provides guidelines for electrical safety, including recommendations for inspection and testing intervals.
It's important to note that health and safety regulations also apply to stationary equipment, such as fridges, washing machines, and other appliances that remain in a fixed position. While these may be considered low-risk due to their infrequent movement, they can still develop faults or damage, especially if they are moved or handled improperly. Therefore, regular inspections and maintenance are crucial for all types of electrical equipment, regardless of their portability.
To ensure compliance with health and safety regulations, employers should implement a comprehensive electrical safety program. This includes regular inspections and maintenance of all electrical equipment, providing proper training to employees on the safe use and handling of appliances, and establishing procedures to promptly report and address any electrical hazards or issues. By following these regulations and maintaining a proactive approach to electrical safety, organizations can help protect their employees, customers, and assets from electrical-related incidents.

Electrical safety
The definition of a portable appliance is crucial for comprehensive safety checks. By understanding what constitutes a portable appliance, testers can ensure that all relevant equipment is inspected and tested. This helps identify potential electrical risks in workplace or domestic settings, reducing the chances of electrical faults, which are a significant cause of fires and electrocution. Regular electrical safety inspections and testing are recommended to ensure compliance and maintain safe working conditions.
The frequency of Portable Appliance Testing (PAT) depends on the risk associated with the equipment and the environment in which it is used. For example, a heavily used drill in the construction industry is considered high risk and would require more frequent testing than a freezer in a kitchen, which is static and poses a lower risk. The Electricity at Work Regulations 1989 require that electrical equipment with the potential to cause injury be maintained in a safe condition, but the regulations do not specify the frequency or methods of inspection and testing.
It is important to note that stationary equipment, such as fridges, washing machines, and other fixed appliances, should not be ignored during PAT. While they are considered low risk due to their infrequent movement, they can still sustain damage, especially if they are moved even slightly. Therefore, regular inspections and testing of all electrical equipment, including stationary items, are essential to ensure electrical safety.
Additionally, it is the employer's responsibility to ensure that work equipment is maintained and in good working order to safeguard employees from electrical shocks and fire hazards. Regular reviews of electrical safety and the Portable Appliance Testing regime are good practices to prevent defective equipment, reduce repair costs, and ensure a safe working environment. Visual examinations and user checks are important components of electrical maintenance, and formal inspections by competent individuals may be required at appropriate intervals.

Risk management
In the context of electrical safety, a portable appliance generally refers to any electrical equipment that is not part of a permanent installation but is connected to a power supply via a plug and socket. The key characteristics of a portable appliance include mobility and transportability. Examples include kettles, toasters, desktop computers, fans, electric drills, vacuum cleaners, and hairdryers.
The risk associated with portable appliances arises from their potential to cause injury or electrical shocks if not maintained or tested regularly. The Electricity at Work Regulations 1989 require that any electrical equipment with the potential to cause harm be maintained in a safe condition. While these regulations do not specify the frequency of inspection and testing, it is generally recommended that portable appliances be tested between three and 24 months, depending on the environment and the nature of use.
To effectively manage the risk associated with portable appliances, organisations should implement a comprehensive inspection and testing schedule. This schedule should consider factors such as the frequency of use, the environment in which the appliance is used, and whether it is double-insulated. Visual examinations and user checks are important aspects of the risk management process, as some electrical safety defects can be identified through simple training and checklists. However, more formal inspections and testing by competent individuals may also be required, especially for combined inspection and testing procedures.
Additionally, it is important to recognise that stationary equipment, such as fridges and washing machines, should not be ignored during risk management processes. While they are considered low-risk due to their infrequent movement, they can still sustain damage, especially if they are moved even slightly. Therefore, regular inspections and testing should also be conducted on stationary equipment to ensure their safety.
