Can you use water to extinguish a grease fire?

Using water on a grease fire is extremely dangerous as it can cause the fire to spread rapidly. When water is poured onto a grease fire, it can instantly vaporize and create a large cloud of steam, which can ignite the surrounding flammable materials and lead to a more intense fire. The behavior of burning grease and water highlights the importance of using appropriate methods for extinguishing such fires.

For grease fires, it is recommended to use a Class K fire extinguisher, which is specifically designed for cooking oils and fats. Alternatively, suffocating the fire with a lid or using baking soda can be effective, as these methods remove the oxygen from the fire or prevent the flames from reaching more fuel. Understanding this is crucial for safety in environments where cooking is taking place.
