May 8, 2026

Quick Answer

For kitchen use, a multipurpose fire extinguisher rated for Class K fires is the best option, as it can effectively extinguish grease and cooking oil fires. Look for an extinguisher rated for Class K fires, with a UL rating of at least 10-B:C.

Choosing the Right Fire Extinguisher for Kitchen Use

When selecting a fire extinguisher for the kitchen, it’s essential to understand the different types of fires and the extinguishers designed to combat them. Class K fires involve flammable liquids, such as cooking oils and greases, which are commonly found in commercial kitchens. These types of fires require a specific type of extinguisher that can effectively smother and cool the flames.

Extinguisher Types for Kitchen Fires

The most common types of fire extinguishers for kitchen use are multipurpose extinguishers rated for Class K fires. These extinguishers contain a dry chemical agent that can effectively extinguish fires involving cooking oils and greases. They are also designed to be safe for use around people and equipment, making them a suitable choice for commercial kitchens. Look for an extinguisher with a UL rating of at least 10-B:C, which indicates that it can effectively extinguish fires involving flammable liquids.

Proper Use and Maintenance of Fire Extinguishers

In addition to selecting the right type of fire extinguisher, it’s also essential to use and maintain them properly. This includes ensuring that the extinguisher is easily accessible, visible, and inspected regularly. Make sure to follow the PASS method when using an extinguisher: Pull the safety pin, Aim the nozzle at the base of the fire, Squeeze the handle to release the agent, and Sweep the nozzle back and forth to extinguish the flames. Regular inspections can help identify any issues with the extinguisher, such as low pressure or a damaged nozzle, ensuring that it remains effective in the event of a fire.
