What is another word for carbon-dioxide foam?
Pronunciation: [kˈɑːbənda͡ɪˈɒksa͡ɪd fˈə͡ʊm] (IPA) 
Carbon-dioxide foam is a substance commonly used in firefighting to extinguish flames. There are several synonyms for this substance, including CO2 foam, carbonic acid foam, and carbonated foam. These terms all refer to the same substance, which is a mixture of carbon dioxide gas and water that is expelled from a foam extinguisher under pressure. This type of fire suppression method is effective for dousing flames in enclosed spaces, as the foam can cover a large area and deprive the fire of oxygen. Other common types of foam used for firefighting include aqueous film-forming foam (AFFF) and alcohol-resistant aqueous film-forming foam (AR-AFFF), which both contain special additives to enhance their effectiveness.
