There is a good chance that when you really need it, the fire extinguisher that you bought eons ago will not work. This is mainly because of poor maintenance and the life span of the system. To counter this problem, we have here the Firearc, a fire extinguisher that uses a chemical reaction to activate. With a simple twisting action, the creation of an instant chemical reaction can activate the salts and help combat the flames. For example, bicarbonate salts and acid mix together and activate to produce a massive amount of carbon dioxide (CO2) that can be incorporated, to streamline the use of the fire extinguisher. This kinda removes an expiry date to the extinguisher.
