More on Extinguisher Labeling
Reference the UL label in the image. The extinguisher classification is:
2-A:10-B:C
The letters (A, B, and C) represent the type(s) of fire for which the extinguisher has been approved.
The number in front of the A rating indicates how much water the extinguisher is equal to and represents 1.25 gallons of water for every unit of one. For example, a 2-A rated extinguisher would be equal to 2.5 (2 x 1.25) gallons of water.
The number in front of the B rating represents the area in square feet of a class B fire that a non-expert user should be able to extinguish. Using the above example, a non-expert user should be able to put out a fire that is as large as 10 square feet.
