Fire safety is a priority in every environment, but it becomes even more essential in places where cooking is involved. Restaurants, commercial kitchens, and bakeries operate under significant fire risk as Class K fires occur from burning cooking oils and greases. These fires operate at extremely high heat levels, which makes standard extinguishers ineffective when attempting to control them. Class K fire extinguishers have been developed to eliminate dangerous fires effectively. Read through to learn what is a class K fire, how their extinguishers work, why they are essential and how to install them.<\/p>\n\n\n\n

Understanding Class K Fires<\/h2>\n\n\n\n

As discussed, a class K fire event refers to any incident that involves heated cooking oils as one of the ignition factors. It is not just the oil itself that ignites but also the vapour generated when it is heated past its flash point. It generates an intense and swiftly spreading blaze. <\/p>\n\n\n\n

Also, the chemical makeup of cooking oils makes them extremely hard to put out using water. In fact, water can forcefully make the burning oil splatter, spread the flames and possibly lead to serious burns.\u00a0<\/p>\n\n\n\n

What is a Class K Fire Extinguisher?<\/h2>\n\n\n\n

The class K fire extinguisher is a perfect partner for kitchens with deep fryers and grills. It has wet chemicals inside, like potassium acetate, potassium carbonate, and potassium citrate, which help fight fires. When you use it on a greasy fire, it shoots out a cool mist that basically puts out the fire by dropping the temperature. It also leaves a layer on the oil, so it can’t start back up again.<\/p>\n\n\n\n

How Do Class K Fire Extinguishers Work?<\/h2>\n\n\n\n

Class K fire extinguishers use saponification. This involves the extinguisher’s wet chemical agent reacting with the hot oil or grease. It forms a soapy foam that smothers the fire and cools the surface. Here\u2019s how they work:<\/p>\n\n\n\n
