Wormald F500 Encapsulator Technology Extinguisher

Effective protection against lithium-ion battery fires


The F500 fire extinguisher has been tested and approved to AS 1841.2 as a water based extinguisher with an additive suitable for use on Class A, B and F fires. Testing witnessed by 3rd party approving bodies KIWA and BSI has also demonstrated F500’s effectiveness on lithium-ion battery capatacies up to 600 Wh and 4.8kWh respectively. When directed at a lithium-ion battery fire it also provides a blanket to drastically reduce toxic smoke emissions.

We encourage you to discuss your individual fire needs with your fire service provider to ensure that you are covered for all fire risks


Due to the rising popularity of li-ion batteries, it’s crucial that businesses and employees who commonly use products and devices powered by lithium-ion batteries understand the associated safety hazards as well as basic handling and storage guidelines to avoid workplace fires and injuries.

F500 encapsulates the flammable electrolytes, rendering them non-flammable.

Encapsulator Technology doesn’t simply put a bandage on the issue at hand. By removing the flammability of the electrolyte and encapsulating the fuel, F500 drastically reduces the risk of reignition.


F500 droplets rapidly reduce heat

Independent testing has shown that F500 rapidly reduces temperature, effectively stopping thermal runaway. This is crucial during lithium-ion fires as every second counts. Each second lost could translate into more and more neighbouring cells rupturing, causing multiple explosions and putting lives on the line.


F500 reduces toxins, including hydrogen fluoride.

This is especially important for lithium-ion fires as the battery’s vapors can be life threatening. When lithium-ion batteries burn, they emit toxic fluoride gasses. Testing shows that when F500 is used, these gasses are drastically reduced.
