PYROCHILL® Formulations are effective for preventing and stopping

Class A, B, C, and most D and K fires.

 

Class A​

The Class A fire is defined as ordinary combustibles. These types of fires use commonly flammable material as their fuel source. Wood, fabric, paper, trash, and plastics are common sources of Class A fires. This is essentially the common accidental fire encountered across several different industries. Trash fires are one such example. 

​

Class B​

The Class B fire is defined as one that uses a flammable liquid or gas as its fuel base. Common liquid based fuel sources include petroleum based oils and paints, kerosene, and gasoline. Flammable gases such as butane or propane are also common fuel sources in Class B fires. Class B fires are a common hazard in industries dealing with fuels, lubricants, and certain types of paint. Smothering these types of fires to remove oxygen is a common solution as are chemical reactions that produce similar effects. Note that cooking fires have their own classification and are defined as Class K fires.

​

Class C​

The Class C fire is defined as a fire that uses electrical components and/or energized equipment as its fuel source. Electrical fires are often fueled by motors, appliances, and electronic transformers. Electrical fires are common in industries that deal with energy or make use of heavy electrically-powered equipment. However, electrical fires can occur on smaller scales in all businesses (i.e. an overloaded surge protector or bad wiring) and should be taken seriously. To extinguish such fires you must first cut the power off and then extinguish the fire.

​

Class D​

The Class D fire is defined as one that uses a combustible metal as its fuel source. Examples of such combustible metals include titanium, magnesium, aluminum, and potassium. Note that there are also other metals with combustive properties you may encounter. Class D fires are a danger in laboratory environments. However, be aware that combustible metals are used as part of production and other industry processes, and you need to be certain of what materials you are using for day-to-day operations. When confronted with such a fire, common extinguishing agents such as water are ineffective and can be hazardous. 

​

Class K​

The Class K fire is defined as a cooking fire involving combustion from liquids used in food preparation. Technically a type of liquid fire, Class K fires are distinct enough to warrant their own classification. Cooking fires are fueled by a wide range of liquid cooking materials. Greases, cooking oils, vegetable fat, and animal fat are all fuel sources found in Class K fires. Class K fires are naturally of concern in the food service and restaurant industry.
