What type of fire extinguisher systems does a Type K license allow for installation and servicing?

The Type K license is specifically designed to allow for the installation and servicing of fixed fire extinguisher systems that are used in commercial cooking areas. This is crucial for environments like restaurants and kitchens, where there is a high risk of grease fires due to the cooking processes involved. Fixed systems that are Type K extinguishers typically use a special wet chemical agent capable of suppressing fires that involve cooking oils and fats, distinguishing them from other fire suppression systems that may not be effective against such hazards.

In comparison, residential range top fire extinguisher systems and portable fire extinguishers might be addressed under different licensing categorizations, but the Type K licensing focuses on larger, fixed systems specifically tailored for the unique challenges presented by commercial kitchen environments. Thus, the correct answer reflects the specialized capabilities granted by the Type K license, which is essential for addressing the risks associated with combustible cooking materials.
