High Voltage Voltage that exceeds 1000 volts AC or 1500 volts DC. (AS 4836).Definition
Incident An actual or an apparently imminent occurrence of an event that endangers or threatens to endanger the safety or health of any person, or destroys or damages or threatens to destroy or damage any property, or any other event or alarm that results in a response by the reporting authority.
Live Work Electrical work performed in circumstances in which some or all of the electrical equipment the subject of the Electrical Work is energised. This includes testing; however, a safety observer
is not required for testing, unless a risk assessment finds that one is required.
Live work includes:
Testing, tightening live or energised terminals, tracing cables through a live switchboard,
vacuuming a switchboard, component removal or replacement or drilling a hole into a live or
The following are examples of Live Work
- Testing components of a television set that’s switched on to carry out a repair
- Testing to ensure correct connections (including polarity)
- Tightening the terminals of live circuit breakers
- Pulling cables into or through a switchboard where there is exposure to live terminals and or energised conductors.
On or Near Proximity to exposed energised conductors where there is possibility of either of the following coming within 500 mm (or other approved distance, exclusions zones) of the energised exposed conductors, whether deliberate, accidental or inadvertent:
- A person’s body.
- Any object, which a person may be carrying or touching during the course of the work that is not designed for use on energised conductors operating at that voltage. (AS/NZS 4836, Section 1.5.20)
Personal Protective Equipment (PPE) Safety clothing and equipment for specified circumstances or areas, where the nature of the work involved or the conditions under which people are working, requires its wearing or use for their personal protection to minimise risk.
Safe System of Work For Live Work on a low voltage electrical Installation, includes, but is not limited to a system of work that complies with the provisions of AS/NZS 4836 (Safe Working on Low Voltage
Electrical Installations) about ensuring the safety of persons while performing Live Work.
Safety Observer In relation to observing for the performance of Electrical Work means a person, specifically assigned the responsibility of observing and warning against unsafe approach to equipment, exposed energised conductors and other potential hazards; (AS/NZS 4836, Section 1.5.22) Who is competent to help, and is suitably trained in the work, and has an understanding of the Electrical Work being performed. Whose competency to help, training and understanding of the Electrical Work performed has been assessed by an approved trainer within the last six months. Who is competent to rescue the person performing the Electrical Work and to provide resuscitation. Whose competence for rescue and resuscitation has been assessed in the last six months.
Having an approved low-voltage rescue kit, that includes gloves and rescue crook that is in current test
date range, at all times throughout the observation. Who must not be employed to perform any other task or
be distracted during the observation.
Example 1: Installation Category 4:
Relates to the primary supply voltage on a main switchboard supplied by a transformer.
An Electrical Worker performing testing or fault finding in this category must have a Safety Observer who will be a duly qualified and licensed Electrician.
Example 2: All other installation categories:
An Electrical Worker performing testing or fault finding in all other situations where the cable size is greater
than 16mm2 and the immediate protection device is rated above 80 amps must have a Safety Observer who
is a duly qualified and licensed Electrical Worker.
Example 3: Emergency
An Electrical Worker performing Electrical Work in an emergency situation must without exception, have a Safety Observer who is a duly qualified and licensed Electrical Worker, when:
- A ‘state of Emergency’ exists as declared by State or Federal Government e.g. severe storms or cyclones.
- A hospital, aged care facility or like facility, where it is imperative that the electrical supply either to the installation or electrical equipment must be urgently restored (within 1-2 hours), the Supply authority supply of electricity is cut – Brown Outs or Black Outs and/or Emergency Back-up generation plant has failed.
- A domestic or commercial installation during a power outage where there is the possibility of a temporary emergency generator being connected and there exists a possibility of back-feeding.
Testing The use of logical methodology or test instruments, or test equipment by a competent person. (AS/NZS 4836, Section 1.5.25)
