"Denios recently started selling large, metal boxes that are specifically designed for storing new or damaged or questionable lithium ion batteries. It’s an option for companies who might be handling a large batch of batteries or for a building where there are many users of e-bikes. They are resistant to fire for up to two hours, allowing a user to toss in and isolate a lithium battery that has exploded or is on fire and then call the fire department for more help."
Seems like a good idea. Amazingly common sensical and non-sensationalized coming from the common media.
