Lithium-ion batteries are everywhere in modern workplaces—powering laptops, power tools, e-bikes, e-scooters, and increasingly, large-scale battery energy storage systems (BESS). But alongside their convenience comes a critical and rapidly escalating fire safety risk that NSW businesses can no longer afford to ignore.

NSW has introduced new mandatory safety standards for e-bikes and e-scooters. Coupled with WHS regulations for large-scale lithium battery storage, evolving Fire and Rescue NSW (FRNSW) guidance, and increasing insurance scrutiny, lithium-ion batteries are now classified as both a high-risk chemical hazard and a critical electrical safety concern.

Why This Matters Now

Unlike traditional electrical fires, lithium-ion battery fires release toxic gases, can reach extremely high temperatures during thermal runaway, and can reignite days after being extinguished. They're harder to detect, harder to control, and pose unique risks to personnel, property, and compliance obligations under WHS legislation.

New Mandatory NSW Safety Standards for E-Bikes & E-Scooters (February 2025)

NSW has introduced mandatory safety standards for e-bikes and e-scooters as declared electrical articles. All e-bikes and e-scooters sold, hired, or supplied in NSW must meet specific safety standards, with certification and marking requirements being phased in. Check NSW Fair Trading for current compliance deadlines.

What Are "Declared Electrical Articles"?

Under NSW Fair Trading regulations, e-bikes and e-scooters are now classified as "declared electrical articles." This means they must comply with:

  • AS/NZS 15194:2018 for e-bikes (electrically power assisted cycles)
  • AS/NZS 60335.2.114:2020 for e-scooters and battery chargers for e-mobility devices
  • Relevant battery safety standards including IEC 62133 (battery cells and packs) and UN 38.3 (transport of lithium batteries)

Some imported devices may also reference overseas standards such as UL 2849 (USA), although this is not an Australian requirement.

Implementation Timeline (Check NSW Fair Trading for Current Dates)

Phase 1
Safety Standards Mandatory
E-bikes and e-scooters must meet declared safety standards
Phase 2
Certification & Marking Required
Products must display compliance certificates and appropriate marking (e.g., RCM mark)

What This Means for NSW Workplaces

  • Courier companies, logistics firms, and delivery services using e-bikes must verify compliance
  • Facilities allowing staff or visitors to charge personal e-bikes/e-scooters should implement clear charging policies and risk assessments
  • Property managers and strata committees must review rules around charging in common areas (see below)
  • Retailers and suppliers may face penalties for selling non-compliant devices

WHS Regulation: Emergency Planning Requirements for Large-Scale Lithium Battery Storage

Under WHS legislation, workplaces storing significant quantities of lithium-ion batteries must treat them as high-risk chemical hazards requiring formal emergency preparedness and consultation with Fire and Rescue NSW.

Large-Scale Storage Requirements

Workplaces storing significant quantities of lithium batteries (including lithium-ion and lithium-metal batteries) may be required to:

  • Lodge an emergency plan with Fire and Rescue NSW
  • Ensure the emergency plan is tested annually (or more frequently as required)
  • Consult with Fire and Rescue NSW on the plan's adequacy
  • Provide information to emergency services about the nature and location of the batteries

High-Risk Workplaces

  • Battery energy storage system (BESS) facilities
  • Large warehouses storing electric vehicles or battery products
  • Battery recycling and disposal centers
  • Manufacturing facilities producing or testing battery systems

Emergency Plan Requirements

  • Identification of hazards and battery locations
  • Evacuation procedures and assembly points
  • Communication protocols with emergency services
  • Fire suppression equipment and training
  • Thermal runaway monitoring and response

Important: All workplaces have duties under the WHS Act to identify, assess, and control risks associated with lithium battery storage and charging, regardless of quantity. This includes smaller-scale operations like offices allowing staff to charge e-bikes or warehouses storing battery-powered equipment. Consult with SafeWork NSW and Fire and Rescue NSW to determine your specific obligations.

Fire and Rescue NSW Research: SARET Program & Critical Findings

Fire and Rescue NSW (FRNSW) conducts ongoing research and provides guidance to better understand and combat lithium-ion battery fires, including work through specialized response teams.

Extinguishing Agent Effectiveness

FRNSW has tested various suppression methods to determine what actually works on lithium fires:

  • Water immersion is the most effective method for cooling cells and preventing thermal runaway spread
  • Standard fire extinguishers (CO₂, dry powder) provide limited effectiveness on battery fires
  • Lithium-specific extinguishers (e.g., AVD, vermiculite-based) can help contain fires but may not fully suppress them

Thermal Runaway & Propagation

Research and operational experience has shown:

  • Single cell failure can trigger cascading thermal runaway across entire battery packs
  • Fires can reach extremely high temperatures and release toxic gases including hydrogen fluoride
  • Reignition risk can remain high for extended periods after initial suppression

Battery Energy Storage Systems (BESS) Guidance

FRNSW has published specific guidance for BESS installations, which are increasingly common in commercial and industrial settings:

  • Mandatory separation distances from buildings and property boundaries
  • Required fire detection and suppression systems
  • Early warning thermal monitoring and gas detection
  • Emergency response protocols and firefighting access

End-of-Life Battery Handling & Disposal

FRNSW research has highlighted disposal as a critical fire risk area. Damaged, degraded, or expired lithium batteries pose extreme hazards during transport and storage.

High-Risk Scenarios

  • • Mixed waste streams (batteries discarded in general rubbish)
  • • Waste truck fires (crushing/compaction triggers thermal runaway)
  • • Warehouse stockpiling of end-of-life batteries
  • • Improper storage leading to short circuits

Best Practice Controls

  • • Dedicated battery disposal bins (separate from general waste)
  • • Terminal taping to prevent short circuits
  • • Use of licensed battery recyclers only
  • • Quarantine areas for damaged/swollen batteries

Strata, Residential & Community Concerns: The Growing Challenge of E-Bike Charging

The rise of e-bikes and e-scooters has created significant challenges for strata schemes, apartment buildings, and shared workspaces. Charging restrictions, insurance implications, and disposal risks are now top-of-mind for building managers across NSW.

Why Strata Schemes Are Restricting Charging

Many strata schemes are now banning or restricting e-bike and e-scooter charging in common areas due to:

  • Fire risk in enclosed spaces: Stairwells, basements, and corridors offer limited escape routes if fires occur
  • Insurance exclusions: Some insurers now exclude or limit cover for lithium battery fires
  • Unregulated devices: Non-compliant batteries and aftermarket chargers increase risk
  • Limited suppression options: Traditional building fire systems may not effectively control lithium fires

Reported Incidents in NSW

Lithium battery fires have been reported in various settings across NSW, including residential buildings and waste collection operations. These incidents highlight the real-world risks and the importance of proper storage, charging, and disposal procedures.

Residential Building Fires

E-bikes and e-scooters charging in shared corridors and common areas have been linked to fires requiring evacuation of residents. Standard building fire suppression systems may not effectively control lithium battery fires.

Waste Collection Incidents

FRNSW reports an increase in waste truck fires caused by lithium batteries discarded in household rubbish bins. Compaction can trigger thermal runaway, often resulting in vehicle fires and service disruptions.

For specific incident data and statistics, refer to Fire and Rescue NSW annual reports and SafeWork NSW publications.

What Building Managers & Strata Committees Should Do Now

  • 1
    Review and update by-laws: Clearly define where e-bikes/e-scooters can be charged (ideally in well-ventilated areas away from escape routes)
  • 2
    Install dedicated charging stations: Consider fire-rated charging lockers or outdoor charging areas with appropriate protection
  • 3
    Communicate with residents: Educate on compliance standards, charging safety, and disposal procedures
  • 4
    Check insurance coverage: Verify that your building insurance covers lithium battery incidents and review exclusions
  • 5
    Provide safe disposal options: Partner with battery recycling services and install dedicated disposal points

How This Applies to Workplaces

The same principles apply to office buildings, warehouses, and commercial premises. If you allow employees or visitors to charge personal devices on-site, you need clear policies, designated charging areas, and appropriate fire safety measures in place. This is part of your PCBU duty under the WHS Act.

Why Lithium-Ion Batteries Are Now Considered a High-Risk Chemical & Electrical Hazard

Lithium-ion batteries present a unique dual hazard classification under WHS legislation—they are both an electrical safety risk and a chemical hazard. Understanding this dual nature is critical to managing them safely.

Electrical Hazard

  • High energy density can cause electrical shock, short circuits, and arc faults
  • Faulty or damaged batteries may discharge uncontrollably
  • Charging equipment and circuits must comply with AS/NZS 3000 (Wiring Rules)
  • Requires testing, tagging, and maintenance like other electrical equipment

Chemical Hazard

  • Contains flammable electrolytes that can ignite and release toxic gases
  • Thermal runaway releases hydrogen fluoride, carbon monoxide, and other hazardous substances
  • Classified as Dangerous Goods (Class 9) for transport and storage
  • Requires specific emergency response protocols and PPE

Understanding Thermal Runaway

Thermal runaway is a self-sustaining chain reaction within a lithium-ion battery where internal heat generation exceeds heat dissipation, causing temperatures to rapidly escalate out of control.

The Process:

  1. 1 Trigger Event: Physical damage, overcharging, internal short circuit, or manufacturing defect
  2. 2 Temperature Rise: Cell temperature rapidly increases beyond safe operating limits
  3. 3 Electrolyte Breakdown: Flammable electrolyte decomposes and may ignite, releasing toxic gases
  4. 4 Propagation: Heat spreads to adjacent cells, triggering cascading failure across the battery pack
  5. 5 Fire & Explosion Risk: Can reach extremely high temperatures, potentially causing venting, fire, or explosion

Once thermal runaway begins, it is extremely difficult to stop. Traditional fire suppression methods are often ineffective, which is why prevention and early detection are so critical.

Why Standard Fire Safety Equipment Isn't Enough

Standard Extinguishers Have Limited Effect:

  • CO₂ and dry powder don't cool the battery cells effectively
  • Fire can reignite even after apparent suppression
  • Toxic gas release continues even without visible flames

What's Actually Required:

  • Lithium-specific fire extinguishers (AVD or vermiculite-based)
  • Water immersion tanks or fire blankets for containment
  • Thermal imaging cameras to detect hot spots
  • Specialist training for emergency response teams
