F-500 EA® Encapsulator Agent Solutions
DEMOFIRE supports F-500 EA® applications for appropriate hazards, including selected lithium-ion, industrial and fire-service scenarios, based on tested configurations and project criteria.

What Is F-500 EA®?
F-500 EA® is an Encapsulator Agent developed by Hazard Control Technologies (HCT) for use with water. HCT positions the product as a water-additive technology that differs from conventional firefighting foam and provides a range of mobile and fixed-system solutions for industrial fires and lithium-ion battery hazards.
DEMOFIRE System Approach
We do not treat an F-500 EA® application as an agent-selection exercise alone. We evaluate the water supply, agent storage, proportioning equipment, pumps, piping, nozzles/discharge devices, detection, automation, commissioning and maintenance as one complete system.

Primary Application Areas
- Lithium-ion batteries and battery energy storage systems (BESS)
- Electric vehicles and charging areas
- Lithium battery recycling facilities
- Vehicles and heavy machinery
- Flammable-liquid/hydrocarbon and industrial special hazards
- Suitable system configurations for data centres and UPS battery areas
Micelle Mist and Fixed Systems
HCT publishes Micelle Mist and various proportioning-system solutions for F-500 EA®. In a fixed system, agent concentration, nozzle type, flow rate and discharge duration should be determined from the protected hazard and the manufacturer’s test and design data for that specific application.
Lithium-Ion and BESS Applications
Battery fire safety is not limited to the suppression system. Cell/BMS monitoring, off-gas detection, electrical isolation, ventilation or deflagration management, exposure control, fire-water strategy and emergency response should be considered together. The suitability of the suppression system should also be compared with test evidence representing the actual cell, module, rack or ESS configuration.
Standards and Test Context
NFPA 18A addresses water additives used for fire control and vapour mitigation. For BESS projects, system-level evaluation may also involve project-accepted installation and test references such as NFPA 855 and UL 9540A.
Technical source: F-500 EA® product and system information should be evaluated together with HCT’s current technical documentation and application guidance. HCT F-500 EA®
Frequently Asked Questions
Is F-500 EA® a foam?
HCT defines the product as an Encapsulator Agent. Its method of use depends on the proportioning and discharge equipment selected for the project.
Is F-500 EA® used with water?
Yes. The product is introduced into the water stream at the concentration specified by the manufacturer for the intended application.
Is F-500 EA® alone sufficient for BESS protection?
No. BESS safety requires multiple protection layers including detection, gas/deflagration management, electrical isolation, layout and separation, exposure control, fire-water planning and emergency response.
