EV Fire Safety for Fleet Managers & Commercial Vehicles
As fleet electrification accelerates across Australia, fleet managers face new WHS obligations around lithium-ion battery fire risk. From overnight depot charging to driver emergency training, we help you protect your people, your vehicles, and your compliance position.

Your WHS Obligations for EV Fleet Fire Safety
Fleet operators have specific legal obligations under the Work Health and Safety Act 2011. As your fleet transitions to electric vehicles, your existing fire safety measures and emergency response plans need to be updated. Here is what you need to know.
Work Health and Safety Act 2011
Under the WHS Act, a Person Conducting a Business or Undertaking (PCBU) must ensure, so far as is reasonably practicable, the health and safety of workers. This includes managing fire risks from lithium-ion batteries in fleet vehicles, charging infrastructure, and depot facilities. Failing to address known EV fire risks could constitute a breach of your primary duty of care.
Safe Work Australia Guidance
Safe Work Australia recognises lithium-ion batteries as an emerging workplace hazard. Employers must conduct risk assessments for any workplace where lithium-ion batteries are charged, stored, or used. This includes fleet depots, overnight charging facilities, and any vehicle fitted with high-voltage battery systems.
Depot Fire Safety for Overnight Charging
Overnight charging of fleet EVs in enclosed depots presents elevated risk. If a battery enters thermal runaway while unattended, the consequences can be catastrophic. Your depot fire safety plan should address detection systems, suppression equipment placement, ventilation, and emergency access for fire services.
Emergency Response Plans
Your existing fleet emergency response plan must be updated to include EV-specific fire scenarios. This includes thermal runaway response procedures, evacuation protocols for depot facilities, and communication procedures with fire services — including advising that the vehicle involved is electric.
Driver Training Requirements
Drivers operating EVs should receive training on what to do if their vehicle shows signs of battery distress — including smoke, unusual smells, or dashboard warnings. They should know to pull over, evacuate, move at least 25 metres away, and call 000 specifying the vehicle is electric.
Insurance & Documentation
Insurers are increasingly asking about EV fire safety measures in fleet operations. Suncorp reported in 2025 that high-value claims involving lithium-ion sources doubled over five years. Documenting your fire safety measures, training records, and equipment inspections strengthens your insurance position and demonstrates due diligence.
Why Standard Fire Systems Aren't Enough
Your depot's existing fire safety systems — sprinklers, standard extinguishers, and smoke detectors — were designed for conventional vehicle fires. Lithium-ion battery thermal runaway in a fleet depot, particularly during overnight charging, is a fundamentally different and more dangerous event.
Extreme Temperatures
Thermal runaway exceeds 1,000°C — far beyond what standard sprinkler systems are designed to suppress.
Toxic Gas Production
Hydrogen fluoride, carbon monoxide, and other lethal gases are produced — a critical danger in enclosed spaces.
Cell-to-Cell Spread
Thermal runaway cascades from cell to cell within the battery pack, causing prolonged and intensifying burning.
Standard Extinguishers Fail
Water, foam, CO₂, and dry powder extinguishers are ineffective at the cellular level of a lithium-ion fire.
48-Hour Reignition Risk
A fire that appears extinguished can reignite up to 48 hours later as cells continue to thermally decompose.
Massive Water Demand
Firefighters may need 30,000+ litres of water to cool an EV battery fire — a major challenge in enclosed facilities.
Recommended for Fleet Fire Safety Package
For fleet depots with EV charging infrastructure, we recommend a comprehensive fire safety package designed for the unique risks of commercial electric vehicles.
Complete EV Fire Safety Package for Fleet Depots
EV Fire Blanket — Commercial Vehicle Size
For fleets with vans, trucks, or buses, we supply fire blankets sized for commercial vehicles. Stored near charging bays in clearly marked wall-mounted bags for rapid deployment. Recommendation: one blanket per charging cluster, plus one at each depot entry/exit.
Lithium-Ion Fire Extinguisher
Mounted at each charging bay or cluster. These specialised extinguishing agents cool the battery below the thermal runaway threshold and suppress the chemical reaction at the cellular level — something standard extinguishers simply cannot do.
Emergency Response Plan & Signage
Updated emergency response plans covering EV-specific fire scenarios, depot evacuation procedures, and fire service communication protocols. Clear signage at charging bays identifying electrical shutoffs and EV fire equipment locations.
Driver & Staff Training Materials
Comprehensive training package covering: recognising signs of battery distress, safe evacuation procedures, EV fire blanket deployment, and communication with emergency services. Includes training register templates for WHS compliance documentation.
Free Download: EV Fleet Fire Safety Assessment Template
A practical assessment template covering depot risk assessment, charging infrastructure safety, emergency response planning, driver training requirements, and WHS documentation. Everything you need to present to your fleet safety manager.
