Class K fire extinguishers are specifically designed for kitchen fires, particularly those involving cooking oils and grease. These fires can be extremely dangerous because they burn at high temperatures and can easily reignite if not properly extinguished. How Class K Fire Extinguishers Work - They use a wet chemical agent (such as potassium acetate, potassium citrate, or potassium carbonate) that reacts with the burning oil to create a soapy foam layer. - This foam smothers the fire, cools the oil, and prevents re-ignition. - Unlike ABC fire extinguishers, which may not be effective on kitchen fires, Class K extinguishers are specially formulated - to handle high-temperature cooking oils. Where Are They Used? - Restaurants & Commercial Kitchens - Food Trucks & Catering Businesses - Home Kitchens (for extra safety)
