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 better practice should always be adopted. If the record of testing is a tag, it should be durable, water resistant, non-metallic, self-adhesive or well-secured, incapable of re-use and have xs bright, distinctive surface. While RCDs significantly 3670 the risk of electric shock they do not provide protection in all circumstances. For example, it may be reasonably practicable to use extra-low voltage electrical equipment such as a battery-operated tool rather than a tool that is plugged into mains electricity.
Should an incident occur as a result of carrying out energised electrical work, the business or undertaking commissioning the work is at risk of being found not to have provided a safe workplace.
A fundamental principle is that the point of isolation should be under the control of the person who is carrying out the work on the isolated conductors. Regulation A person conducting a business or undertaking carrying out electrical work must keep: The electric shock ss be received by direct or indirect contact, tracking through or across a medium, or by arcing.
A person conducting a business or undertaking has the primary duty under the WHS Act to ensure, so far as is reasonably practicable, that workers and other persons at the workplace are not exposed to electrical risks arising from the business or undertaking. nxs
The person carrying out any testing of electrical equipment should also be competent to interpret the test results of any equipment they use. Portable plug-type RCDs can be plugged into a socket outlet to protect a single piece of equipment.
The electrical equipment may also be fitted with a tag stating: Tools, instruments and equipment that are poorly maintained, inappropriately used or not fit for purpose can cause zs, for example: These types of ladders should be avoided for any kind of electrical work.
Log books and similar records have the advantage of: General workplace health and safety risk control measures should be used in these nzx. Procedures involving coordination, such as procedures related to switching circuits or equipment on and off during the fault finding or testing process, must be implemented and maintained at all times.
Arrangements should also be put in place to ensure, so far as is reasonably practicable, that all persons at the place receive suitable and adequate information and instruction, for example about the need 376 comply with warning or safety signs and xs out of any no go zones.
Section 46 A person conducting a business or undertaking must, so far as is reasonably practicable, consult, cooperate and coordinate activities nss all other persons who have a work health or safety duty in relation to the same matter.
They may also incorporate a risk assessment. For example, testing requiring the dismantling of electrical equipment should only be carried out by a licensed electrician. Risks associated with electrical work may arise from: The following risk factors associated with carrying out electrical work should be considered: Regulation A record of testing must be kept until the electrical equipment is next tested, nzss removed from the workplace or disposed of.
Without regular testing and tagging, staff or employees run the risk of operating defective and unsafe electrical equipment, which can cause serious or possibly even lethal injuries including electric shock and even potentially start electrical fires.
This will reduce the risks associated with poor electrical equipment. The is a joint Australian and New Zealand Standard that describes the in-service safety inspection, testing method and frequency of electrical appliances.
First aid in the workplace. You must work through this hierarchy to choose the control that most effectively eliminates or minimises the risk in the circumstances, so far as is reasonably practicable. The ways of controlling risks are ranked from the highest level of protection and reliability to the lowest. In some circumstances the risks associated with undertaking electrical work near exposed live parts can be equivalent to those associated with live electrical 360.
The tools, instruments and equipment used by electrical workers often have special design characteristics, for example many are insulated. Alternatively, it could be replaced or permanently removed from use. Unsafe electrical equipment should be labelled indicating it is unsafe and must not be used.
This exemption does not extend to the electricity 376 sector. Persons can be exposed to electrical risks, including risks of electric shock, arcing and explosion, without directly contacting exposed energised parts of electrical equipment.
It may be safer and more cost-effective to ensure all circuits are protected by one or more RCDs rather than selectively install individual RCDs at some socket outlets to accommodate your current workplace needs, which may change.
AS/NZS | On Call Maintenance
Use engineering control measures to minimise the risk, for example installing residual current devices to reduce the risk of receiving a fatal electric shock. Is the work area clear of obstructions to allow for easy access? Any testing or fault finding on energised parts must be carried out in accordance with requirements for energised electrical work, which are discussed in Section 7 of this Code. Many electrical defects are detectable by visual inspection. This ranking is known as the hierarchy of risk control.
Working near sources of arcing, explosion or fires.
AS/NZS 3760:2010 – Electrical Safety Standard
I ncidents that expose a worker or any other person to a serious risk from an electric shock must be notified to the regulator and may also be notifiable separately to an electrical safety regulator. Inadequate maintenance may lead to serious electrical risks, for example nxs medium might conceal a mechanical defect that could cause an open circuit in a testing device.
These persons may also have duties under local electrical safety laws. These types of controls should be used in conjunction with additional control measures, such as danger tags and permit systems. Locking off methods incorporating danger tags. The WHS Regulations include more specific requirements for managing electrical risks at the workplace.
Before commencing any testing or fault finding in an energised environment: That is why the WHS Regulations prohibit energised electrical work subject to certain exceptions.
