Control measure knowledge

Personnel should isolate high-voltage systems to reduce the risk of accidental activation or electrocution.  

Information sources such as the driver, manufacturer’s guidance or information stored on mobile data terminals may assist in identifying the appropriate method of isolating an alternative fuel vehicle (AFV), such as using an emergency shut-off. 

Some AFVs have sensors in the engine compartment that will automatically isolate the high-voltage supply in a collision.  

Removing the proximity key more than five metres from the vehicle is likely to isolate high-voltage systems; however, this can lead to deadlocked doors.

Strategic actions

Fire and rescue services should:
  • Provide personnel with access to up-to-date information on alternative fuel vehicles - TPT

  • Consider obtaining specialist advice from vehicle manufacturers about alternative fuel vehicles that can be provided to personnel when required 

  • Consider making electrical gloves available for personnel to use at incidents involving live electricity supply

Tactical actions

Incident commanders should:
  • Identify isolation points for alternative fuel vehicles (AFV)

  • Consider making electrical gloves available for personnel to use at incidents involving live electricity supply

  • Avoid any contact with high-voltage systems

  • Consider the appropriate use of electrical gloves, in line with service procedures

  • Consider the presence of residual electrical charge in high-voltage systems

  • Power down the alternative fuel vehicle using the manufacturer’s guidance
