Japan Invented The Fire-Extinguishing Chemical Grenade
So, here's how it works; when an early-stage small fires breaks out in an enclosed space, throw the container at the source of the flame and the ammonium phosphate dibasic and ammonium bicarbonate chemical combination extinguishes the fire like magic. Each container has about 22 ounces of liquid on the inside and can last up to five years
The chemical solution inside each container has an extinguishing capacity ten times that of water and keeps those in trouble out of harm's way.
Plus having the power to put out a fire with one throw basically makes you one of the X-Men.
