Abstract
A soda-acid fire extinguisher system reacts to the sensing of a fire in a building and starts a chemical reaction inside a sealed container. The chemical reaction produces carbon dioxide and water which is piped to the fire location and is sprayed on the fire by a nozzle. The fire extinguisher may also be manually activated and a nozzle is hand-held for extinguishing the fire.
