Managing risks

Only licensed or registered electricians should carry out electrical work. A person conducting a business or undertaking (PCBU) must also: 

  • provide safe and suitable electrical equipment – for example, not using leads and tools in damp or wet conditions unless they’re made for those conditions 

  • inspect leads for damage before use and remove any damaged leads 

  • work out why a residual current device (RCD), circuit breaker or other over-current protective device disconnected the electricity before you switch it back on. 

Arrange equipment to manage risk

You should arrange your equipment properly to manage electrical risks.  

Arrange electrical leads to avoid damage by: 

  • not running leads across the floor or ground, through doorways and over sharp edges 

  • using lead stands or insulated cable hangers to keep leads off the ground 

  • using cable protection ramps or covers to protect cables and cords, where applicable. 

Manage power circuit overload risk 

You can prevent overloading power circuits when you: 

  • provide enough socket outlets – using adaptors to overload socket outlets can cause fires 

  • use the appropriate-rated fuse or circuit breaker to prevent overloading 

  • if the circuit keeps overloading – not increasing the fuse rating as this creates a fire risk because of overheating 

  • using battery powered tools instead of mains operated where possible 

  • use RCDs where required. 

Managing risks with overhead and underground electric lines 

To manage the risks of working near electric lines: 

  • de-energise lines and equipment if possible 

  • identify line voltage and insulation 

  • consult with workers, electricity supply authorities, and PCBUs 

  • decide safe approach distances and work zones. 

Overhead lines 

Other steps to manage the risks of overhead lines include to: 

  • assess line visibility, height, sway and sag 

  • consider site conditions, including weather, ground, and traffic. 

Underground lines 

Other steps to manage the risks of underground lines include to: 

  • identify line locations – if you’re going to repair potholes, for example 

  • use insulated hand tools.

Managing risks of solar power systems 

Since solar panels or photovoltaic (PV) systems typically go on a roof, this adds risks from working: 

  • near overhead electric lines and equipment 

  • at height – risk of falls from roof or through ceiling space 

  • in ceiling spaces – risk of exposure to asbestos, extreme heat, energised electric lines  

  • outdoors – exposure to ultraviolet radiation, heat, wind, and other weather. 

Sunlight or batteries energise PV systems. They can be hazardous even when disconnected or shutdown at the switchboard.  

Construction work on or near energised PV systems is high-risk construction work and requires a Safe Work Method Statement.
