• The K-GUARD liquid agent fire extinguisher is specifically designed for use on fires that involve combustible cooking vegetable or animal fats in commercial cooking equipment. Typical appliances include: fryers; griddles and range tops; upright, natural charcoal, or chain-type broilers; electric, lava rock, mesquite or gas-radiant char-broilers; and woks. Newer, more efficient cooking appliances, plus the use of non-saturated cooking oils, require a fire extinguishing agent which will not only smother a fire but provide a cooling effect. The extinguisher is ideally suitable for use in restaurants, hospitals, nursing homes, hotels, schools, airports, and other similar facilities.
