ALL Fire Extinguishers have a UL Rating on them that tells you what type of fire that it has been tested and approved to suppress.

For example, if a fire extinguisher has a rating of 2A:10BC it means that it is rated to be used on a fire that is 2 square feet of a Class A fire or 10 square feet of a Class B or C type fire.

So the size that you need depends on what type of fire is expected in that specific area.    You can always use a fire extinguisher that has a higher rating than what is required (ie if your fire marshall tells you that you need a 1A:10BC, you can use a 2A:10BC).


NFPA 10 specifically details what size and type of fire extinguisher is required for each type of hazard. If you would like a copy of NFPA 10, please email us and we will be happy to send it to you.
