Fire Extinguishers and Fire Blankets

What do the UL Ratings mean?

UL stands for Underwriters Laboratories

  • Class A

    Fires involving wood, Paper, cloth, trash, plastics (solids that are not metals).

  • Class B

    Fires involving flammable liquids and vapors, such as gasoline, oil, grease, acetone.

  • Class C

    Fires involving electrical Currents.

  • Class D

    Metal fires (magnesium, sodium, potassium and sodium-potassium alloys).

  • Class K

    Cooking oil fires (mainly relating to fires in restaurants).

Classes A fires relate to homes and households, and are among the most common. They involve "ordinary" combustibles such as wooden furniture, paper trash, clothing and curtains, and ever the kind of rubber found in your shoes.

Unlike in Europe and Australia, all flammable liquids and gases are Class B in the United States. These are the kind of elements you will usually found in your garage, workshop and kitchen.

Class C relates to electrical fires and electrical equipment.

In relation to Class A, you multiply the number in front of the letter by 1.25 to to give you how much water the extinguisher contains. For example, a Rating of 2-A shows the unit contains 2.5 gallons of water.

For a Class B Rating, the number shows how many square feet the extinguisher can suppress.

Classes C, D, and K do not have a numerical rating.

So, an extinguisher with a 2-A:10-B:C Rating. This translates to it containing 2.5 gallons of water, that it can suppress fire over 10 square feet, and it's suitable for fighting fires in the A, B, and C classes, as described above. 

We have written more about fire suppression, the different types of fire extinguishers, and the Classes of fire.
