Make Sure You Have the Right Extinguisher — Know How to Read the Label!

November 8, 2013

Fire Extinguisher ClassYou may know what a Class A fire extinguisher is, as opposed to a Class B, C, D, or K (if you don’t click here), but what does it mean when the label says 2A:20B:C?

The numerical rating before letters A or B have to do with the size of fire that particular extinguisher was designed to handle. In the example above, you’ll notice no number in front of the C; this is because there is no numerical rating placed on C, D, and K extinguishers.

The number in front of the A refers to the amount of water the extinguisher is equal to; each unit representing 1.25 gallons. In the example above, this extinguisher has the same effectiveness as 2.5 gallons of water.

The number preceding the B indicates the area, in square feet, of the fire that extinguisher can handle. In this case, the extinguisher was designed to extinguish a fire up to 20ft x 20ft.
