New concept for novel fire extinguisher in space. Researchers have developed a new concept of fire extinguishing, named Vacuum Extinguish Method. VEM is based on the 'reverse' operation of the conventional fire extinguishing procedure: It sucks the combustion products, even flame and the firing source itself, into a vacuum chamber to clean up the firing zone. This concept is advantageous for space use, as it prevents the spread of harmful combustible products throughout the enclosed cabin. Source 3n.
Compared to the regular CO2 fire extinguisher the new one will be easier to deal with, not just with space but with anything that humans cannot come out simply (Like underwater, gaseous environments, etc). Maybe hopefully, as time progresses the public may have this as a better alternative to fight fires.
