Air pressurised water extinguishers (class A) are filled with tap water two-thirds of the way and then filled with pressurised air the rest of the way. Carbon Dioxide extinguishers (class B) are filled with non-flammable carbon dioxide and have no pressure gauge. Dry Chemical (class C) are filled with carbon dioxide and halon gas.
