5. Class K extinguishers.
To produce fires that include combustible food preparation liquids like fats as well as oils, utilize a class K extinguisher. Considering that a few of the chemical agents/compounds utilized to suppress kitchen fires are electrically conductive, switch off power outlets initially.
