Features of Class K Fire Extinguisher
A class K fire extinguisher has several features that make it a reliable weapon for you during class K fire emergencies. Some of the major features include the following:
Wet Chemical Agent: Class K extinguishers utilize a specialized wet chemical agent that reacts with cooking oils, fats, and greases to form a soapy foam. This foam acts as a barrier, preventing the release of flammable vapors and suppressing the fire.
Enhanced Cooling Properties: The wet chemical agent in Class K extinguishers also provides superior cooling properties, which help to reduce the temperature of the fire and prevent re-ignition.
Discharge Mechanism: Class K extinguishers are often equipped with a low-velocity discharge nozzle or spray applicator designed to apply the wet chemical agent in a gentle and controlled manner.
Compatibility with Kitchen Appliances: Class K extinguishers are designed to be compatible with commercial kitchen appliances. They can be used safely on stovetops, deep fryers, grills, and other cooking equipment.
Different Types of Class K Fire Extinguishers:
Here are some common types of Class K fire extinguishers available:
| Class K Fire Extinguishers | Features |
| Stored-Pressure Wet Chemical | Utilizes a stored-pressure system to deliver a wet chemical agent effectively. |
| Cartridge-Operated Wet Chemical | Utilizes a cartridge system for pressurization, delivering a wet chemical agent efficiently. |
| Pre-Engineered Kitchen System | A fixed fire suppression system specifically designed for commercial kitchens. It automatically releases a wet chemical agent when a fire is detected. |
When to Use a Class K Extinguisher?
A Class K fire extinguisher is designed for use in commercial kitchens and areas where cooking oils, fats, and greases are present. It is specifically intended to combat fires involving flammable liquids used in cooking, such as vegetable oils, animal fats, and more.
