“Technologies are available that are able to contain portable electronic devices which are actively involved in a lithium-ion battery failure. While there have been several of these containment devices on the market, few have featured both adequate protection for the person attempting to contain the device and a method for suppressing a fire after containment. New technology now can protect the person moving the device and contain it safely. Incorporation of this technology is recommended in passenger aeroplanes.”
The “New Technologies” mentioned, would be a fitting description of the FLIGHT FIREBOX.
