Fire Extinguishers

When purchasing fire extinguishers for home or office, it is vital to ensure that the chosen extinguisher is rated correctly for the environment and the likely combustables it will be used for. A summary of UL fire classification ratings is below. 

Note: The number indicates the extinguisher’s relative power against that class of fire. For example, an extinguisher with a 2A rating is twice as powerful against common combustible fires as a 1A extinguisher. Class C and D do not have numerical ratings.
