A revolutionary self activating device, the E Fire USA Fire-extinguishing Ball (EFB) provides a much needed additional line of defense for fighting fires. As a passive method, mount your EFB in areas of concern where a possible fire can occur. Examples: Switchboard and circuit control system, electric appliance areas, electrical outlet, deteriorated or damaged electrical wire areas, battery power bank, lithium-ion battery charger, engine room, kitchen, boiler room, washer and dryer. In active use, the EFB can be thrown, released or launched into an active fire. Whether in a fixed position providing 24/7 coverage or used manually, the patented EFB ELY6 allows any user to mitigate a fire.
