A revised Standard for the safety inspection and testing of electrical equipment has recently been published. ‘The revisions to AS/NZS will. 2. Joint Australian New Zealand Standard. In-service safety inspection and testing of electrical equipment. Superseding AS/NZS A. The AS/NZS is an Australian Standard that oversees the Test and Tag industry in regards to electrical safety of portable appliances.

The following questions will help you evaluate how nas you are currently managing electrical risks in az workplace: You should implement a safe system of work to deal with potentially unsafe electrical equipment at the workplace. When disconnecting the installation or equipment from supply, a method should be applied to ensure the equipment is not reconnected while the work is carried out.
A risk assessment can zns determine: The tag may also be colour-coded to identify the month in which the testing was carried out. Where appropriate, test leads and testing devices need to be provided with suitable fuse protection.
This Code is divided into two parts dealing with: Redesigning equipment or work processes could involve designing and installing equipment that does not have energised parts near the work area. Safe work method statements must be developed in consultation with relevant workers. Non-portable RCDs installed at a fixed socket outlet provide protection to electrical equipment plugged into the outlet. Inspection and testing of electrical equipment must be carried out by a person who has acquired, through training, qualification or experience, the knowledge and skills to carry out the task i.
Energised live means connected to a source of electrical supply or subject to hazardous induced or capacitive voltages. Regulation A person conducting a business or undertaking with management or control of electrical equipment must ensure that the electrical equipment is regularly inspected and tested by a competent person if the electrical equipment is: This duty requires eliminating electrical risks or, if that is not reasonably practicable, minimising the risks so far as is reasonably practicable.
Cutting cables presents particular risks.
This could mean shorter downtime and not having to work live, lessening or eliminating the risk of exposure. The two relevant types are: While RCDs significantly reduce the risk of electric shock they do not provide protection in all circumstances. Is the isolation point clearly marked or labelled and capable of being operated quickly?
After faults and fires, often in emergencies, electrical workers may be exposed to unsafe atmospheres. For this purpose, you must consider all relevant matters, including the following: For example, direct contact causing electrocution, fire or explosion causing serious burns 7360 death. Preventing workers from coming into contact with the source of an electrical hazard will reduce the relevant risks.
Special requirements for safety observers apply in relation to certain energised electrical work. All reasonable steps must be taken to ensure that restoring electricity supply following isolation does not pose risks to health and safety at the workplace.
Persons conducting a business or undertaking with management or control of a workplace have a duty to ensure effective residual current devices RCDs are used in certain high-risk environments as defined in the regulations.
AS/NZS | Electrical Safety Standard
Inhaled hot gases and molten particles can cause serious internal burns to the throat and lungs. The method of extinguishing fires should be addressed. Should an incident occur as a result of carrying out energised electrical work, the business or undertaking nsz the work is at risk of being found not to have provided a safe workplace.
Risks associated with electrical work may arise from: Toxic gases and lack of oxygen can cause illness and death.
Particular care must be taken regarding the condition of the insulation on leads, probes and clips of test equipment. The standard test regime is to test a known source of energy, test the de-energised circuit for zero volts then test the known source again.
This may involve a single control measure or a combination of two or more different controls. Energised electrical work must not be carried out unless the safety risk to those persons directly affected by a supply interruption is higher than the risk to the licensed or registered electrical workers proposed to carry out the energised electrical work.
However, administrative controls such as procurement and personnel policies and procedures are very important in relation to electrical risks, as they will help to ensure that electrical aa is carried out by a qualified 360 as required by law.
You must ensure, so far as is reasonably practicable, that the information, training and instruction is provided in a way that is readily understandable by any person to whom it is provided. Insulated tools and equipment must be suitable for the work and be maintained in good working order, including by regular maintenance, inspection and testing.
In these situations, you should exchange information to find out who is doing what and work 360 in a cooperative and coordinated way so 37600 all risks are eliminated or minimised so far as is reasonably practicable. This Code provides practical guidance for persons conducting a business or undertaking on managing electrical risks in the workplace. Regulation A record of testing must be kept until the electrical equipment is next tested, permanently removed from the workplace or disposed of.
For more information you should seek further advice about ns on or near high-voltage electrical installations from a specialist electrical contractor or the local electricity supply authority.
For more information about maintaining and inspecting tools and equipment, including testing and fault finding instruments, see Section 9 of this Code. These types of ladders should be avoided for any kind of electrical work.
The following factors may be taken into account in assessing risks: Danger tags are used for the duration of the electrical work to warn persons at the workplace that: The reason this Standard is used for test and tagging purposes is because it is recognised as credible document and is a reference document for many industries, organisations etc. You must also manage risks to health and safety arising out of electromagnetic hazards, including eliminating the risk so far as is reasonably practicable.
If the electrical equipment is required to be tested regularly for safety, take the necessary steps to ensure that it does not miss its first required test. Proximity voltage testers should be tested for correct operations immediately before use and again immediately after use, particularly if the test result indicates zero voltage, to confirm that the instrument is still working correctly.
