Control measure
Instruct people to evacuate safely from high-voltage electricity

Control measure knowledge

A person that is in an insulated or protected position may be forced to leave it if it becomes too hazardous for them to remain. When leaving their position, they should be instructed to jump away, ensuring they break all contact before touching the ground. 

To assist people with their safe evacuation, non-conductive equipment such as rubber airbags may be provided for them to jump or step onto as they leave. 

Evacuate an exclusion zone 

If a person has to move within the hazard area to reach a position of safety, one of the following methods should be used to minimise the effects of the equalisation of voltages: 

  • Shuffle, keeping both feet close together, maintaining contact with the ground at all times  
  • Hop, making sure that both feet hit the ground at the same time  
  • Make leaping strides, so that one foot is off the ground at all times 

Strategic actions

Fire and rescue services should:
  • Establish arrangements with local distribution network operators (DNOs) and transmission operators (TOs), and maintain up-to-date emergency contact details in their fire control rooms 

  • Identify equipment that is constructed of a non-conductive material and communicate to relevant personnel

Tactical actions

Incident commanders should:
  • Implement an exclusion zone of at least 10m, subject to risk assessment 

  • Consider providing equipment, such as rubber airbags, to assist people evacuating

  • Instruct people about the safe method for evacuating an insulated or protected position
