As a way to promote fire safety, Samsung came up with the "Firevase". It is a usable vase, but the structure contains a double wall filled with potassium carbonate, a extinguishing agent. The idea is that it can be thrown at a fire, and will break to disperse the agent, and is able to extinguish small house fires. Currently on sale in Sourh Korea, selling about 200,000 units a year. It's credited with raising the national level of households with fire extinguishers by 8%. www.theverge.com/2019/3/28/18285253/samsung-firevase-throwable-fire-extinguisher-south-korean-awareness-campaign |

making a throwable fire extinguisher decorative is a bit of an innovation, though the throwables, themselves are old technology.
the biggest thing fire safety groups is pushing is that you STILL call for the fire department, because there have been multiple incidents where someone delayed calling because hey thought they could put it out themselves, and ultimately lost their home or workplace.

Wonder if it will put out a Samsung smart phone fire.

Wonder if it will put out a Samsung smart phone fire. I'm guessing not. Lithium chloride and graphite extinguishing agents are recommended for lithium fires. www.fireengineering.com/articles/print/volume-131/issue-6/features/metal-fires-require-knowledge-of-proper-extinguishing-agents.htmlI couldn't find documentation, but I suspect that despite the fact that the mixture of water and potash- being essentially a mixture of two combustion byproducts - may still be cracked by the lithium fire and be able to be re-burned - considering that we are warned not to use CO2 for that reason. if we get another round of mythbusters, that might be a cool episode: "can water/CO2/potash/etc burn?" I'd say side by side testing with calorimeters. burn the fuel, alone, and then burn it with the subject material added and see if it produces more heat. |

Can you use a Class D fire extinguisher to put out a lithium battery fire?

I remember someone created a "Samsung battery recharging station" that consisted of a few layers of shrink wrap atop a clear plastic container filled with water.
The logic was that if the device overheated and caught fire, it'd melt the plastic shrink wrap and end up in the water, extinguishing the fire.
...But presenting a shock hazard instead.
