The cost of replacing a fire extinguisher varies. For example, ours range from a little over $30 for a 2.5 lb. Buckeye ABC fire extinguisher to over $300 for our 20 lb. Buckeye CO2 model. In contrast, recharging and doing full testing on a fire extinguisher usually ranges from about $20 to $70.
Lower damage to appliances: If a pot is burning, a fire blanket might put out the fire and save the stove. On the other hand, a fire extinguisher will get dry chemicals all through the appliances, which may cause further damage. Less corrosive: ABC fire extinguishers have a caustic resin that can cause metals to corrode. Fire blankets do not.
Choosing and Using Fire Extinguishers
When operating a fire extinguisher, tell residents to remember the word PASS: Pull the pin. Hold the extinguisher with the nozzle pointing away from you and release the locking mechanism. Aim low. Point the extinguisher at the base of the fire. Squeeze the lever slowly and evenly.
Fire Extinguisher Sizes. The size of a fire extinguisher indicates the amount of extinguishing agent it holds and is most often measured in pounds. Sizes can range from as small as 2.5 lb. to as large as 350 lb. While the largest extinguishers will come with built-in wheels to make transportation manageable, size is always important to consider.

Why choose a different fire extinguisher for each application?
Fire extinguishers are uniquely designed to meet the needs of a variety of applications, so it’s important to choose the one that’s right for you. For example, a different extinguisher may be needed for a commercial kitchen as opposed to a clean room or library.
Is a fire extinguisher better than a blanket?
We feel a fire extinguisher is a better choice for extinguishing an incipient fire that’s hard to access and cover with a blanket. For example, you can’t extinguish a small fire burning in the corner of a room – or it’ll be hard to do so. But a fire extinguisher can blast dry chemicals into the corner and extinguish the fire with ease.
