Managing the risk of working near powerlines

Determine power line voltage

Question/challenge the need to work in the vicinity

Identify the owner of the power lines (often a regional energy distributor) and consult their guidance information. In some instances this guidance information requires contact with the distributor

Conduct a comprehensive machinery risk assessment of site, conditions, task, machinery to be used and loads to be shifted

The results of this assessment must then be used to eliminate or minimise risks posed by suitability or otherwise of machinery, conductive loads, site or other environmental conditions – using a combination of control types as listed below

Arrange for the energy network operator to isolate the power supply and de-energise the lines

Use a machine that cannot encroach upon the minimum approach distances for the type of power lines involved

Utilise interlocks or other forms of machine control adjustment and limitation so that the machine cannot be operated in a way that will encroach minimum approach distances

Develop and utilise a comprehensive safe work methods statement for the task, which will often or always include:

a. Highlighting presence of powerlines with signage, tiger tails, bunting etc

b. Using trained staff and observers, and implementing warning signals to ensure plant does not encroach on minimum distance requirements

c. Implementing and enforcing strict exclusion zones

d. Ensure staff are trained in emergency procedures in the event of a machine becoming energised at any point during commissioning, decommissioning or during the task

Utilise (as set out in SWMS, and depending upon voltage, conditions and SWMS contents) PPE such as insulated gloves, mats and so on
