What is the correct way to extinguish a Class K fire involving cooking oils?

The proper method for extinguishing a Class K fire, which involves cooking oils and fats, is to use a Class K fire extinguisher or a fire blanket. Class K fire extinguishers are specifically designed to handle the unique challenges posed by cooking oil fires. They utilize a special agent that cools the burning oil and creates a barrier between the fire and the oxygen, effectively smothering the flames without causing a dangerous reaction.

A fire blanket can also be useful in this scenario as it can smother the fire and cut off its oxygen supply, preventing it from spreading. In contrast, using water is not advisable as it can cause the burning oil to spread, creating an even larger hazard. A dry chemical extinguisher may not effectively address the specific characteristics of a Class K fire, and sprinkling salt could be insufficient and potentially ineffective in controlling the flames. Therefore, using a Class K extinguisher or fire blanket is the most effective and safe approach to extinguishing these types of fires.
