Electric vehicles (EVs) are becoming more prevalent as consumers select greener transport options. EVs contain a multiple banks of lithium-ion batteries therefore possible risks are involved if the battery banks are compromised. This includes if the EV is involved in a road crash or there is a charging incident. Charging a compromised EV can begin the thermal runaway process. It is obviously significantly larger than a battery used on a battery operated tool, therefore it is difficult for the NTFRS to suppress. Currently the NTFRS are in national working groups in regards for industry practices to contain a EV fire incident.
- Make sure that your EV is identifiable by emergency services. There should be a blue “EV” sticker/badge on the number plate to indicate that it is an electric or hybrid vehicle. These stickers are there specifically to warn emergency responders of the presence of a high voltage battery. Information on the requirements is available from the NT MVR.
- When installing charging equipment, ensure the charging cable and/or unit is electrically compliant and installed by a qualified electrician to AS/NZS 3000 Electrical Installations “Wiring Rules”, Appendix P Guidance for Installation and Location of Electrical Vehicle Socket-Outlets and Charging Stations.
- NTFRS recommends that a smoke alarm or a heat alarm is installed in garages where an EV is regularly parked or charged. Only have a licenced electrician install and interconnect mains-powered devices where possible. Check with the manufacturer or distributor to ensure device models are compatible for interconnection.
- When charging your EV, only use extension leads and power sockets that areprovided for use in the charging of electric vehicles. Always exercise caution when charging in wet weather, and especially during electrical storms.
If any incident occurs involving an EV
If an incident (road crash or fire) involves a vehicle that is identified as a EV the NTFRS request that the following information is passed on through your 000 call.
- That there is a vehicle involved with identifying blue triangle on the number plate.
- If there is evidence of the black/grey coloured steam type substance being emitted from the vehicle to evacuate the area immediately, stay atleast 30 metres up wind of the area.
- Do NOT try to extinguish the vehicle, the extinguisher is insufficient to complete the task and you will be putting yourself at risk.
Once the NTFRS arrive they will investigate the incident further and make the scene safe with specialised equipment that they carry on the fire appliances.
If anyone has been exposed to spilled electrolyte, flying debris, smoke or vapours, or flames, seek urgent medical assistance. Burns should be immediately treated with cool running water for 20 minutes. Burns larger than a 20-cent piece require emergency care. Treat with cool running water immediately, call Triple Zero (000), and follow the advice of the operator.

Damaged electric vehicles (EVs)
An electric vehicle that has been involved in a collision, a fire, or has been submerged, must be treated with caution as the high voltage battery pack may be compromised. Damaged EV batteries may ignite hours, days, or even weeks after the initial incident.
Contact the sales point, service point or vehicle manufacturer for advice.
Do not charge or use the vehicle unless it has been inspected and cleared by a qualified technician.
Damaged EVs should be kept in an open area at least 15 metres from other vehicles, buildings, and/or other exposures.
Damaged EVs require specialised towing specialists to remove from an incident scene to a safe area.
