What type of suppression system should be used in kitchens to handle grease fires?

A Type K suppression system is specifically designed to address fires that involve cooking oils and fats, which are common in kitchens. These systems utilize a wet chemical agent that not only cools the flames but also forms a barrier on the surface of the burning grease, helping to prevent re-ignition. The effectiveness of a Type K system lies in its ability to tackle the unique challenges posed by high-temperature grease fires, making it essential for commercial kitchens where such hazards are prevalent.

In contrast, other types of fire suppression systems are not suitable for kitchen fires. For example, Type A systems are aimed at ordinary combustibles like wood and paper, Type B systems are designed for flammable liquids, and Type C systems are meant for electrical fires. Each of these systems uses different agents that would not effectively suppress a grease fire, which can lead to danger if the wrong type is used. Therefore, the Type K suppression system is the most appropriate and essential choice for ensuring safety in kitchen environments.
