Beyond ABE Powder | Why AS 2444 is Evolving for Lithium-Ion Battery Risks

The E-Scooter in Apartment 402: A 2026 Story

Imagine it’s 2:00 AM in a modern apartment complex in Wollongong. In Apartment 402, a delivery rider is sleeping soundly while his e-scooter charges in the hallway. It’s a cheap, aftermarket battery—one of thousands currently circulating in the Illawarra. Suddenly, a “pop” echoes through the room, followed by a violent hiss.

The rider wakes up to a jet of blue-white flame shooting from the battery pack. He grabs the “standard” red fire extinguisher from the hallway—a 4.5kg ABE Dry Chemical Powder unit, exactly what AS 2444 suggested when the building was signed off in 2022. He pulls the pin and unleashes the powder.

The flames vanish for three seconds. Then, they explode back to life, hotter and more violent than before. The powder has done nothing to stop the Thermal Runaway happening inside the cells. By the time Fire and Rescue NSW (FRNSW) arrives, the hallway is a toxic soup of hydrogen fluoride gas, and Apartment 402 is a total loss.

In April 2026, our digital reports showed 28 key events on our AS 2444 resource page. Why? Because property managers across Sydney are realising that the “standard” extinguishers they’ve relied on for decades are fundamentally incapable of stopping the fastest-growing fire threat in Australia.

In the post-February 13th world, “compliance” isn’t just about having a red can on the wall; it’s about having the right tool for the modern hazard.

The Birth of “Class L”: The 2026 Regulatory Shift

For years, we’ve fought fires using five main classes (A, B, C, D, and E). But as of early 2026, the international fire safety community (including emerging Australian advisory notes) has begun recognising a new, specialised threat: Class L fires.

What is a Class L Fire?

Class L refers specifically to fires involving lithium-ion batteries. Unlike a Class A fire (wood/paper) or a Class B fire (liquids), a lithium-ion fire doesn’t need external oxygen to burn. The battery creates its own oxygen as the internal chemistry breaks down.

The 2026 Stats You Need to Know

• The Frequency Crisis: In 2025, Fire and Rescue NSW recorded 332 lithium-ion battery incidents—nearly one every single day.

• The Escalation: Data from 2026 shows that lithium-ion fires are now the fastest-growing home and commercial fire risk in New South Wales and Western Australia.

• The Insurance Gap: Insurers are now specifically asking property managers: “What is your mitigation strategy for e-mobility and energy storage on-site?” If your answer is “Standard ABE Powder,” your premiums are likely to skyrocket.

Thermal Runaway: The Monster Inside the Battery

To understand why your current AS 2444 setup might be failing, you need to understand the science of the enemy. Lithium-ion batteries don’t just “catch fire”; they undergo Thermal Runaway.

The Chain Reaction

Thermal runaway is a chemical feedback loop.

1. Stage 1: The Short: An internal separator fails (due to damage or overcharging).

2. Stage 2: The Heat: The cell begins to heat up rapidly.

3. Stage 3: The Breach: At approximately 150°C, the cell vents flammable, toxic gases.

4. Stage 4: The Propagation: The heat from one cell triggers the cell next to it. Within seconds, you have a 1,000°C blowtorch that cannot be “suffocated” because it’s generating its own fuel and oxygen.

Why “Standard” Extinguishers Fail the Class L Test

If you walk down your building’s corridor right now, you’ll likely see a Dry Chemical Powder (ABE) or a Carbon Dioxide (CO2) extinguisher. Here is why they are legally and technically insufficient for lithium-ion risks in 2026.

1. The Powder Problem (ABE)

Dry powder works by “suffocating” a fire. It creates a blanket that cuts off oxygen. The Failure: Since lithium-ion fires create their own oxygen internally, the powder blanket is useless. The fire continues to burn underneath the powder, often “erupting” back through the crust once the extinguisher is empty.

2. The CO2 Limitation

CO2 works by displacing oxygen and providing a small amount of cooling. The Failure: The cooling effect is far too weak to stop the thermal runaway of a high-energy battery. The moment the CO2 gas dissipates, the battery (which is still at 700°C+) will instantly re-ignite.

3. The Water Danger

Standard water extinguishers can actually make a lithium-ion fire worse. In some cases, the water reacts with the lithium and other chemicals to produce explosive hydrogen gas.

The Recovery Solution: F-500 Encapsulator Technology

In May 2026, “Compliance Recovery” for AS 2444 involves a technical upgrade to F-500 Encapsulator Agent technology. This is the “Authority Choice” we are seeing across high-risk Sydney commercial sites and strata buildings.

How F-500 Works (The “Three-Pronged” Attack)

F-500 isn’t just a foam or a powder; it’s a surfactant that works on a molecular level through a process called Micelle Encapsulation.

1. Rapid Cooling: F-500 reduces the surface tension of water, allowing it to penetrate deep into the battery cells. It absorbs heat 6 to 10 times faster than plain water, yanking the temperature of the battery down below the “runaway” threshold instantly.

2. Encapsulation: The F-500 molecules surround the flammable electrolytes and toxic gases (like hydrogen fluoride), wrapping them in a “chemical cocoon” that renders them non-flammable and non-explosive.

3. Interruption: It breaks the free-radical chain reaction of the fire, preventing the fire from jumping to the next battery cell.

Navigating AS 2444 in the 2026 Audit

When we perform an audit this month, we aren’t just looking for the date on the tag. We’re looking at Hazard Mapping.

The “Lithium-Ion Charging Zone” Audit

Under the 2026 interpretations of AS 2444, if your building has a designated area for e-bikes or scooters, it must be treated as a Specific Hazard.

• The Requirement: You cannot rely on a corridor extinguisher 20 meters away. You need a specialised Class L / F-500 unit within 10 meters of the charging point.

• The Signage: You need clear, 2026-compliant signage that identifies the extinguisher as “Lithium-Ion Suitable.”

The Handyman Trap: Wrong Mounting

We frequently see property managers buying “specialist” extinguishers online and having a handyman screw them into a drywall without a proper backing board. The 2026 Fail: If the extinguisher isn’t mounted at the correct height (usually between 100mm and 1200mm from the floor) or on a compliant bracket, it’s a Critical Defect. Why? Because in a fire, if the bracket fails and the extinguisher falls, it can discharge accidentally or become a projectile.

The Financial Fallout: $66,000 and the “Strict Liability” Offence

Why did we see 28 events on our AS 2444 page in April? Because the “she’ll be right” attitude toward extinguishers died on February 13th.

1. Compounding Council Fines

In 2026, NSW councils treat “Inadequate Portable Assets” as a strict liability offence. If your AFSS is rejected because you have the wrong extinguishers for your hazard, the fines start at $1,000 for week one and can escalate to $6,000 per week.

2. The Insurance “Forensic” Investigation

If Apartment 402 (our delivery rider) burns down, the insurer’s first question will be: “Did the building comply with AS 2444 for the known risks on-site?” If they find you were charging 50 e-bikes in a basement with only two ABE powder extinguishers, they can argue you were grossly negligent, potentially leaving the strata committee to cover the millions in damages.

3. The 5-Yearly Discharge Trap (AS 1851)

In May 2026, many extinguishers are hitting their 5-Yearly Pressure Test window. Most contractors will just tell you to “buy new ones.” The Authority Move: Use this 5-yearly window to perform a “Tech Refresh.” Instead of buying more useless powder, transition your building’s high-risk zones to F-500 technology.

Your 4-Step AS 2444 Recovery Roadmap

If you’re worried about your building’s portable fire assets, here is your May action plan.

1. The Hazard Mapping Audit: Walk your building. Identify every e-bike, every scooter, and every server room. These are your “Class L” danger zones.

2. The F-500 Transition: Replace outdated or unrated extinguishers in these zones with F-500 Encapsulator Agent units that are certified to AS/NZS 1841.

3. The Signage Refresh: Ensure your signage matches the new 2026 standards, including specific identification for lithium-ion risks.

4. Digital Asset Management: Get rid of the paper tags. Every extinguisher should have a Digital QR Code that allows you to see its pressure, its last service date, and its “Hazard Rating” on your phone.

Don’t Let an Outdated “Red Can” Be Your Downfall

The fire risks in Sydney are changing. Our buildings are fuller of energy than ever before. In the 2026 NSW landscape, “compliance” is about matching your defence to the actual threat.

Stop the risk of a failed AFSS and the nightmare of a lithium-ion runaway. Let’s get your AS 2444 hazard mapping audited, your extinguishers refreshed with F-500 technology, and your building’s safety verified for the modern world.
