Managing electrical hazards on farms

Last updated: 14 April 2026

Farms rely on electrical equipment every day, making it essential to manage the associated risks. Regular checks and safe work practices help prevent shocks, fires and serious injuries.

Powerlines, power points, switchboards and residual current devices

Electrical hazards on farms can arise from overhead and underground powerlines, as well as power cords, fittings, machinery, tools and electrical installations. Identify and assess these hazards for the likelihood and severity of potential injury or harm and develop safe work procedures to control them. Any suspect items should be immediately removed from service, tagged out and either isolated or kept in a safe place until repaired or discarded.

RCDs (residual current devices) provide a high level of personal protection from electric shock because they switch off immediately when electricity ‘leaks’ to earth at a harmful level.

To help manage electrical risks on farms, take the following precautions:

  • check the location of overhead and underground power lines before work starts
  • inspect, check and test electrical installations regularly
  • keep flammable chemicals more than 1 m away from sources of energy
  • waterproof or protect outside power boards from water
  • clearly label main isolation switches and RCDs and ensure they are accessible.
     

Plugs, leads and damage

A competent person, such as an electrician, should regularly inspect and test wiring, cords, plugs, tools and equipment.

Electrical equipment should be inspected for visible damage, such as deteriorated insulation or evidence of shorting or sparking. Tools with damaged casings, cords or plugs must not be used. To help reduce electrical risks:

  • inspect tools and leads for damage
  • use heavy duty extension leads suitable for the work environment
  • wear appropriate personal protective equipment (PPE) when using electrical tools
  • fit RCDs to electrical installations where handheld and portable electrical tools are used.
