This recharge container is designed for service technicians and facilities that need to recharge E-FireX extinguisher units after discharge, and for operations using TRPL-E in fire engine foam tanks, fixed suppression systems, or high-volume response equipment.\u003c\/p\u003e\n      \u003cp\u003eTRPL-E is a water-based encapsulator agent that works by rapidly cooling lithium battery cells while simultaneously forming a mineral encapsulation barrier around the fire source. This barrier traps flammable vapors and toxic off-gassing, prevents oxygen from reaching the combustion zone, and dramatically reduces the risk of re-ignition — the most dangerous characteristic of lithium battery thermal runaway events. The agent is 100% all-natural, biodegradable, fluorine-free, and contains no PFAS, PFOS, or PFOA chemicals. It proportions readily for use with a wide range of foam and suppression equipment, and its performance characteristics make it a practical replacement for AFFF in applications where PFAS-free compliance is required.\u003c\/p\u003e\n      \u003cp\u003eThe 5-gallon container provides enough agent to recharge multiple E-FireX portable units or stock a service vehicle for field recharging operations.

Lithium-ion battery fires are addressed within existing fire classifications depending on the materials involved, with suppression strategies typically emphasizing sustained cooling consistent with Class A fire response principles. E-FireX is actively working with NFPA on draft language for a new \"L\" classification for lithium battery fires.\u003c\/p\u003e\n    \u003c\/div\u003e\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\u003cspan class=\"accordion-title\"\u003eAgent Properties and Performance\u003c\/span\u003e\u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\u003cdiv class=\"accordion-content-inner\"\u003e\n      \u003cp\u003eTRPL-E is a mineral-based suspended encapsulator agent, not a chemical foam concentrate.
