If there are any exposed conductors in the immediate work area they should be separated by design or segregated and protected with insulated barricades, insulated shrouding or insulated material to prevent against inadvertent or direct contact. A record of testing must specify the following: Only in extremely rare circumstances would it be possible to justify that it is not practicable to have a short break in supply. Testing and fault finding low-voltage equipment and installations.

If this occurs, the worker is using a device that is conducting fault current. The plan should address the risks associated with the operation and maintenance of the high voltage installation. In some circumstances the risks associated with undertaking electrical work near exposed live parts can be equivalent to those associated with live electrical work. The tools, testing equipment and PPE for testing and fault finding must be suitable for the work, properly tested and maintained in good working order.

For example, the action of cutting a multi-core control cable is likely to create a risk if secondary current from a current transformer is present. The most common electrical risks and causes of injury are: For work on energised electrical equipment, the WHS Regulations require that a risk assessment be prepared in writing by a competent person; for more information see Part B of this Code.

The PPE should be rated for the work to be done. Formal or on-the-job training may be appropriate depending on the circumstances.

The testing method including the 7360 used must be safe and effective. Contact with earth occurs through normal body contact with the ground or earthed metal parts. No-one should operate an isolator or knowingly use equipment where the isolator has a control mechanism attached. The risk management process If in doubt you should ensure that portable RCDs are provided to these workers and take all reasonable steps to ensure they are used.

Examples of training are: Electric shocks from faulty electrical equipment may also lead to related injuries, including falls from ladders, scaffolds or other elevated work nnzs. Designers and manufacturers of electrical equipment or installations must ensure they are designed and manufactured so that electrical risks are eliminated or, if this not reasonably practicable, minimised so far as is reasonably practicable.

The out of service or caution tag should: Regulation A person with ass or control of a workplace must take all reasonable steps to ensure that residual current devices used at the workplace are tested regularly by a competent person to ensure the devices are working effectively. Nxs electrical hazards may be identified in a number of different ways including: Testing equipment used for detecting an energised source should be trialled first to prove that it is functioning correctly immediately before and after the test has taken place.

Fixed socket outlet RCD unit. Modifying or repairing existing low-voltage electrical installations. General Guidance — Use. For example, direct contact causing electrocution, fire or explosion causing serious burns or death. Tagging systems should also be used at the point s of isolation where possible for general information.

Non-portable RCDs installed at the main switchboard protect the wiring connected to the RCD and electrical equipment plugged into the protected circuit. Regulation A person conducting a business or undertaking must ensure that electrical work is not carried out on electrical equipment while the equipment is energised, subject to the prescribed exceptions discussed in Section 7 of this Code.

The electrical risks and consequences of an electrical incident involving high voltage may be significantly higher than low voltage.

Other factors that may affect consequence and likelihood include: A record of testing other than daily testing must be kept until the device is next tested or disposed of.

Where a formal permit system is used, all reasonable steps must be taken to ensure that the designated sign-on and tagging procedures are followed.

The controls that are put in place to protect health and safety must be reviewed regularly to make sure they work effectively. The record 376 be in the form of a tag attached to the electrical equipment tested. These persons will also have duties in relation to the health and safety of the electrical worker s and other persons at the place where the electrical work is being carried out.

A fundamental principle is that the point of isolation should be under the jzs of the person who is carrying out the work on the isolated conductors.

Replacing a hazardous process or material with one that is less hazardous will reduce the hazard, and hence the risk. The barrier must be erected safely.

After faults and fires, often in emergencies, electrical workers may be exposed to unsafe atmospheres.

At regular frequencies from every 3 months to every 5 years dependent on the factors or considerations listed belowyou should have your electrical appliances and equipment inspected, tested and tagged labelled. You may need to seek technical advice from a competent person about the kinds of RCDs nzzs are appropriate for your workplace.

What Is AS/NZS 3760?

Managing the risks of electrical work. Electrical equipment is unsafe if there are reasonable grounds for believing it to be unsafe. Insulated barriers should be of suitable material to effectively separate electrical workers from adjacent energised equipment.

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. This includes taking reasonable steps to ensure that the business or undertaking has and uses appropriate resources and processes to eliminate or minimise electrical risks at the workplace.
