Contents of Fire Extinguishers Dry chemical-smothers-contains potassium bicarbonate or potassium chloride-leaves mildly corrosive residue-used on Class C fires ABC fire extinguisher leaves a yellow powder which has a sticky residue. Can damage computers or other appliances and is irritating to skin and eyes. It contains a graphite-type chemical.
Contents Halon-gas that interferes with chemical reaction that occurs when fuels burn-used on Class C fires
