Why do they use carbon dioxide in fire extinguishers?
Carbon dioxide (later sodium bicarbonate) extinguishers were used to knock down the flames and foam used to prevent re-ignition of the fuel fumes. “Foaming the runway” can reduce friction and sparks in a crash landing, and protein foam continued to be used for that purpose, although FAA regulations prohibited reliance upon its use for suppression.
When were soda-acid fire extinguishers invented?
