Explanation
Class K (NFPA classification) covers fires in cooking appliances involving high-temperature cooking oils and animal or vegetable fats. These fires occur in commercial galley deep fryers and griddles. Wet chemical agents (potassium acetate/potassium citrate) are the correct extinguishing agent — they saponify the fat and create a barrier. Water or dry chemical can cause violent splatter.
