SMART Safety Powerlines

A power line does not have to be touched to lead to serious or fatal injury. Electricity can leap if a person or vehicle simply gets too close – it’s called a flashover. The type of machines used in farming are particularly at risk because they tend to be high or have long equipment, like combines or sprayer booms.   

Would you understand what to do if you or someone else was involved in a power line accident? It is crucial you act fast and understand the danger properly. Take a look at this quick read. A few minutes to refresh your knowledge could save lives.   

 

Be more aware of power lines 

It is very likely you will have power lines on your land. Always assume they are live until told otherwise. They can be easily mistaken for telephone lines. Map out all the lines on your land so you know which are live. This will be useful for ensuring everyone on your farm, including new contractors, is aware of the lines and familiar with clearance heights. Really important if you are working in the dark.

Need to know 

  • Do not store materials, stack bales or store crops underneath overhead power lines. 
  • Follow the 10-metre rule – if your equipment could make contact ALWAYS keep it 10-metres away. 
  • Be aware, if rubber boots or gloves are dirty or damp they may not protect you from a fatal shock. 

Do this in an overhead power line accident 

  • Stay calm, keep clear and call for help. 
  • Identify the line and where you are. 
  • Call your local electricity supplier – keep the number in your cab. 
  • Stand clear of any machinery in contact with the power line. Touching it could be fatal. The driver of a vehicle which has come into contact with an overhead power line should remain safe by staying in the cab.   
  • Keep everyone else out of the way. 
  • Call the emergency services. 

Assist an injured person safely  

  • Tell them to STAY in the cab until the power network confirms the line is off. 
  • Ask the driver to DRIVE clear of the wires – if they can. 
  • If the cab is unsafe, for example, on fire, the driver should JUMP WELL CLEAR – do NOT use the vehicle’s stairs.  
  • They should make leaping strides with one foot off the ground at all times until at least 5-metres away.   
  • NEVER RETURN TO THE VEHICLE – power lines can re-energise without warning.
