Gases and liquids should be regarded as conductive. Alternatively, a different system may be put into place to ensure the electrical equipment is properly inspected and tested as required e. These authorities may be covered by separate electrical safety requirements. Section 19 A person conducting a business or undertaking must ensure, so far as is reasonably practicable, the provision of any information, training, instruction or supervision that is necessary to protect all persons from risks to their health and safety arising 3670 work carried out.
Duty holders may have additional legal obligations under state or territory electrical safety legislation. In deciding between options for non-portable RCDs, you should consider the size of the building or site, its use, and any plans to refurbish, refit or rewire the building.
RCDs work by continuously comparing the current flow in both the active supply and neutral return conductors of an electrical circuit. Administrative controls involve the use of safe work practices to control the risk, for example establishing exclusion zones, use of permits and warning signs.
This may require isolating the electricity supply while the barrier is installed. For example, direct contact causing electrocution, fire or explosion causing serious burns or death.
Persons conducting a business or undertaking who have a high voltage electrical installation should prepare an Installation Safety Management Plan for their workplace. Fixed socket outlet RCD unit. Contact Comply Zs nationwide 3670 or use the online enquiry form on this page to learn more about the AS NZS safety regulations.
AS/NZS 3760:2010 – Electrical Safety Standard
Where appropriate, test leads and testing devices need to be provided with suitable fuse protection. High fault currents — working, testing or fault finding energised. This risk may not be initially apparent; that is, the cable cutters may not be damaged when the cable is cut. A record of testing other than daily testing must be kept until the device hzs next tested or disposed of.
Section 47 A person conducting a business or undertaking must consult, so far as is reasonably practicable, with workers who carry out work for the business or undertaking and who are or are likely to be directly affected by a work health and safety matter.
The record may be in the nzx of a tag attached to the electrical equipment tested.
Appendix C may be used to assist with identifying hazards and assessing risks in carrying out electrical work. The control mechanism should require a deliberate action to engage or disengage the device. The following requirement only applies if it is reasonably practicable to provide an RCD in the higher risk workplaces: Electrical work must not be carried out on electrical equipment while energised only because it is merely more convenient for the electrical equipment to stay energised while the work is being carried out.
Arcs may cause severe burns to the skin and flash burns to the face and eyes. By drawing on the experience, knowledge and ideas of your workers you are more likely to identify all hazards and choose effective risk controls.
Electrical equipment is unsafe if there are reasonable grounds nzss believing it to be unsafe.
What Is AS/NZS 3760?
sa The tag may also be colour-coded to identify the month in which the testing was carried out. Depending on the construction of the scaffold, a number of sections may need to be bonded to ensure an equipotential state.
The electrical worker carrying out the testing must understand testing procedures and be competent in the use of the tester. If this occurs, the worker is using a device that is conducting fault current. If the work is incomplete, for example at a change of shift, the last person removes their danger tag or lock and replaces it with a warning tag e. A competent safety observer must be present when work is carried out on energised electrical equipment, unless the work consists only of testing and a risk assessment shows that there is no serious risk associated with the proposed work.
For example, it may not be reasonably practicable to eliminate energised electrical work altogether; however, even if it is necessary for one of the legally permissible reasons to work on an energised electrical part, it may be possible to de-energise the surrounding parts. For more information about the applicable electrical licensing or registration laws contact the local regulator in the relevant jurisdiction.

This ranking is known as the hierarchy of risk control. Working de-energised on low voltage electrical equipment or circuits requires the electrical equipment or circuits to be effectively isolated from all relevant sources of electricity supply. This includes conditions that involve exposing the electrical equipment to moisture, heat, vibration, mechanical damage, corrosive chemicals and dust. Modifying or repairing existing low-voltage electrical installations.
