Electrical safety is an important aspect in occupational health and safety (OHS) for which regulation is available in the legislation of Australia and New Zealand that requires Portable Appliance Testing (PAT). This is a part of the Electricity (Safety) Regulations 2010 and OSH Regulations AS/NZS3760/2010 “In-service safety inspection and testing of electrical equipment” to ensure maintenance of electrical equipment in a safe condition.
What is Portable Appliance Testing (PAT)
Portable Appliance Testing (PAT) is a mandatory procedure of regular inspection and electrical testing of electrical equipment, leads and plugs which is needed to ensure safety of the users. For this purpose, all electrical appliances in the transportable or portable category require a periodical safety check. The portable appliances include any equipment with flexible cable and/or plug fitted for mains operation such as computers, microwaves, fans, heaters, vacuum cleaners, table lamps, handheld tools etc.
Wide applicability of Test and Tag NZ
These appliances require testing for Test and Tag NZ standard. The Electricity (Safety) Regulations 2010 is applicable on many premises like offices, factories, shops, hotels, restaurants, construction sites, schools/universities, religious places, community halls, and many other commercial and non-commercial places. The applicability is not restricted to owned places but rented properties also and the places where electrical appliances are repaired or rented. In short, the Regulation has wide applicability. The electrical appliances or equipments used in any of the above premises require compulsory testing for continued electrical safety. The necessity of this requirement is due to access of appliance by the general public. Any outside equipment brought to the premises also attracts provision of these regulations.
Periodicity of Test and Tag NZ standard
There is on fixed rule about the periodicity of testing under Test and Tag standard of these regulations because the rules may vary based on influencing factors like environment, users, equipment type, and equipment construction. This variation is due to the degree of risks involved by the exposure or use of electrical equipment or appliance.
