This procedure should be read in conjunction with the Facility and Electrical Safety suite in the UQ Policy and Procedures Library.

This procedure applies to UQ workers on all UQ campuses and sites, including controlled entities. For the purposes of this procedure, the definition of UQ workers is broad and is intended to ensure UQ meets its responsibilities under the Work Health and Safety Act 2011 (Qld) (WHS Act). The definition of UQ workers is provided in the appendix.

1.1    Legislative context

UQ’s legislative compliance obligations in relation to electrical safety are provided under the Electrical Safety Act 2002 (Qld) (the ES Act) and the Electrical Safety Regulation 2013 (Qld).

1.2    Definition of electrical work

For the purposes of this procedure, electrical work at UQ includes electrical work as defined in the ES Act that is undertaken at UQ locations, including as part of:

  • maintenance and repairs to infrastructure and electrical equipment

  • installation of electrical equipment/infrastructure

  • manufacture of electrical equipment

  • research and development activities

  • teaching, learning and training

  • emergency response.

2.0    Process and Key Controls

  1. All electrical work completed at UQ must meet regulatory requirements and comply with relevant UQ policies and procedures.

  2. A risk assessment in UQSafe must be completed before the commencement of any energised work (excluding testing), unless completing emergency works, in which case a Safe Work Method Statement must be followed.

  3. All other electrical work must have a risk assessment, or Standard Operating Procedure (SOP) or Job Hazard Analysis (JHA) or Safe Work Method Statement (SWMS) completed before being undertaken.

  4. Only persons that are appropriately licensed and qualified are permitted to undertake any electrical work  at UQ locations. Students undertaking electrical work as part of their studies must be supervised by a UQ authorised electrical worker. Engineering students have limited exemptions that can be found in section 3.4.5.

  5. High voltage (HV) electrical work including installation, operation and maintenance of HV installations is only to be undertaken by the Property and Facilities (P&F) Division, or specialist approved HV electrical contractors engaged by P&F. All workers must have the required training and competency prior to commencing (refer section 3.2.2).

  6. All work needing to be completed in HV and Low Voltage (LV) switch rooms must have written approval by the P&F precinct Client Facilities Manager (CFM) before any work commences via an Entry Permit (PF626).

  7. Electrical contractors undertaking electrical infrastructure work must be engaged by P&F. Specialised electrical work, such as work on ITS/research installations or equipment, or on electric vehicles may be undertaken by other electrical contractors, upon authorisation of local HSW manager and must comply with all relevant UQ policies and procedures.

  8. Electrical contractors undertaking work as part of a construction project are under the control of the Principal Contractor.

3.0    Key Requirements

3.1    Risk management

The hierarchy of risk control must be considered for developing and implementing control measures. The control measures are developed and implemented by the UQ authorised electrical worker according to an approved UQSafe risk assessment, and/or Standard Operating Procedure (SOP) or Job Hazard Analysis (JHA) or Safe Work Method Statement (SWMS) depending on local area requirements. Refer to the Health and Safety Risk Assessment Procedure for more information.

3.1.1    Job Hazard Analysis (JHA) / Risk Assessments (RA) / Safe Work Method Statements (SWMS)

JHA, RA or SWMS should be based on associated electrical risks which are dependent upon the class of hazards, tasks, things, or circumstances. They are to be completed by the competent and authorised UQ worker for the Organisational Unit and should outline the controls necessary to appropriately manage the risks associated with the electrical work.

Further guidance in assessing electrical risks is initially available from UQ HSW Managers or WHS Coordinators.

3.2    Controls

3.2.1    Isolation

Equipment isolation points must be physically locked out with a padlock and locking device, with a tag or notice affixed to the lock or isolation point describing why and by whom the isolation was implemented (refer to the Lock Out Tag Out Isolation Safety Guideline).  Isolation and tagging practices communicate the risks involved with the electrical equipment or the installation.

3.2.2    Competency and training

UQ workers working on electrical equipment/infrastructure must have the required licences along with the skills and knowledge to understand the hazards associated with the tasks. Organisational Units must ensure that all UQ workers involved in or potentially affected by the work activities are provided with information, training and instruction which is suitable and adequate having regard to:

  • nature of the work carried out

  • nature of the risks associated with the work

  • control measures implemented

  • operational use of electrical equipment to relevant workers.

Records of all training provided to UQ workers for working with electricity must comply with the Keeping Records at UQ Procedure (Business Category – ‘Workforce Management’).

3.2.3    Personal Protective Equipment (PPE)

PPE must be used where determined to be an appropriate control measure, either in combination with other higher order controls or as a stand-alone measure, through the risk assessment, JHA or SWMS process or where stated in Regulations. Where electrical work is to be undertaken on or near exposed energised conductors or live conductive parts, the minimum requirement for PPE is:

  • eye/face protection

  • protective clothing and footwear

  • hand protection, such as insulating or flame-resistant gloves.

The type and rating of PPE and tools used will be determined based on the risk assessment for the electrical equipment and the type of electrical work being performed.

For low voltage work, the Safe working on or near low-voltage electrical installations and equipment standard (AS/NZS 4836:2011) should be considered as a basis of selecting appropriate PPE and tools. Insulating covers and mats used for electrical safety purposes must comply with the Insulating mats for electrical purposes standard (AS/NZS 2978). Similarly, insulated barriers must be of suitable material to effectively separate electrical workers from adjacent energised equipment.

3.2.3.1    Arc Flash (PPE)

An arc flash is a release of electrical energy that causes an explosion which can reach temperatures of up to 20,000 degrees Celsius. Arc flashes may result in causing serious burns, injury, and death as well as damage to property and equipment.

The Safe working on or near low-voltage electrical installations and equipment standard (AS/NZS 4836:2011) specifies situations where arc flash PPE might be required. Arc flash PPE is required where an elevated risk of arc flash is identified during the risk assessment. Additionally, arc flash PPE is required where electrical work is to be undertaken on a live or near exposed energised conductors or live conductive part carrying current exceeding 800 Amps.

3.2.4    Emergency response

A UQ Emergency Response Plan (ERP) must be developed by UQ workers familiar with emergency procedures at workplaces prior to commencing electrical work. The Work, Health and Safety Regulation 2011 and the Managing the work environment and facilities code of practice 2021 stipulate the need for emergency and rescue procedures when working with electrical hazards. ERPs should include:

  • effective response to an emergency

  • evacuation procedures

  • notifying emergency service organisations at the earliest opportunity

  • medical treatment and assistance

  • effective communication between the authorised person coordinating the emergency response and all persons in the workplace

  • testing of the emergency procedures, including the frequency of testing

  • Information, training, and instruction to relevant workers in relation to implementing the emergency plan.

3.3    Reporting electrical injuries and incidents

Injuries or incidents that occur as a result of electrical equipment or electrical work must be reported in UQSafe.  Criteria apply to some electrical injuries and incidents that require them to be notified initially to the HSW Division, and then to the electrical safety regulator.  Refer to Health and Safety Incident and Hazard Reporting Procedure. For notifiable incidents and injuries involving electricity, an incident investigation will be undertaken (refer to the Incident Investigation Procedure).

3.4    Conduct of electrical work

3.4.1    Licence requirements

The Electrical Safety Act 2002 (Qld) defines an electrical work licence as a licence authorising an individual to perform electrical work (as defined in the Act).

Authorised electrical workers, including electrical contractors, must hold valid and relevant licences and accreditation, and be trained and appropriately competent to undertake electrical work at UQ locations.

UQ has an electrical contractor’s licence for the design, manufacture, and supply of electrical equipment. UQ is required to keep their licence valid by engaging the following positions:

This licence is kept by the HSW Division.

For more information on licence requirements for specific electrical activities, contact your local HSW Manager.

3.4.2    High voltage (HV) work

High voltage (HV) electrical work including installation, operation and maintenance of HV installations is only to be undertaken by P&F, or specialist approved HV electrical contractors engaged by P&F.

For access to HV equipment or substations where work will be undertaken, there are several permits/processes that must be obtained, completed, and approved by the relevant authorised person before any works can commence.

3.4.3    Energised work

Energised or ‘live’ work will not be approved unless it is permitted electrical work under section 18 of the Electrical Safety Regulation 2013 (Qld), which prohibits work on energised electrical equipment except under the following conditions:

  • the electrical equipment worked on provides a vital health and safety function

  • it is necessary that the electrical equipment be energised for the work to be carried out properly

  • for the purposes of required testing

  • there is no reasonable alternative.

Electrical work on energised electrical equipment must only be conducted by UQ authorised electrical workers according to an approved risk assessment in UQSafe, unless completing emergency works, in which case a SWMS must be followed.

3.4.4    Testing / de-energising

Before electrical work is performed on electrical equipment, it must be tested to ensure it is not energised. All precautions must be taken to prevent de-energised equipment from being inadvertently re-energised by isolating and locking out circuits/equipment intended to be worked on (refer to the Lock Out Tag Out Isolation Safety Guideline). All exposed conductors must be treated as live until tested and proven to be de-energised.

For specific plant and equipment, additional precautions or steps may need to be taken to ensure safe de-energisation and re-energisation. These steps should be addressed by local SOPs or management plans.

3.4.5    Electrical work under supervision

The Electrical Safety Act 2002 (Qld) provides an exemption for an engineering university student to perform electrical work as part of training under the supervision of teaching staff, which must be a practising professional engineer under the Professional Engineers Act 2002 (Qld) without the requirement to hold an electrical trade license. All safety requirements of an UQ authorised electrical worker will apply to the student and teaching staff. Organisational Units seeking this exemption must obtain explicit written permission from the Head of the Organisational Unit. The relevant supervisor (e.g. the practising professional engineer) must additionally complete a risk assessment in UQSafe including specific controls for managing the risks to staff, unlicenced students and others.

3.4.6    Restricted Access

Controls must be in place to prevent unauthorised access to equipment while it is being repaired or maintained.  Controls may include locked access, barricading and signage at entry to notify UQ workers and others of the electrical hazards. Refer to the Temporary Barricading and Signage Guideline for additional information.
