Putting Out Fires 101: The Fire Extinguisher Types


Fire extinguishers are probably one of the most recognizable safety devices around. You’ll know it once you see it. But not many people know that the contents within fire extinguishers vary, and not all of them can be used to douse certain types of fires. If you ‘re in the market looking for a fire extinguisher product for sale, here are a few pointers to consider.


According to Fire Foe, the first thing you need to know before purchasing fire extinguishers on sale is that there are class ratings for these devices. There are four known fire extinguisher classifications, namely:

  • Class A – used for fires from combustible materials such as paper and wood
  • Class B – is a fire extinguisher used for putting out gasoline, oil and grease fires
  • Class C –should only be used for electrical fires
  • Class D – is used to extinguish fires caused by flammable metals

Chemical Content

If you can afford to purchase only one type of fire extinguisher for your home, choose a multiclass rating fire extinguisher. This is also recommended for an area that may produce more than one type of fire, as these contain chemicals that can put out fires from different causes safely. Also, choose a fire extinguisher product that has been tested and certified by an independent laboratory. Look for a label on the side of the device to determine if indeed it has undergone such testing and certification. The certification informs the customer that the device is safe to use and effective to snuff the type of fire for which it was manufactured.


Size is also an important factor to consider when buying a fire extinguisher. The size of the device is listed directly on the extinguisher itself. It has details on the area that a particular fire extinguisher can handle. The two most common sizes you can purchase are size 5 and 10. A size 5 can handle at least 12.5 square feet of fire, whereas a size 10 can handle at least 25 square feet. Take measurements of the room where you intend to place the fire extinguisher. Also, consider the type of activities that will regularly occur there. For example, if you use welding torches in a workshop regularly, then you’ll need to get a bigger type of fire extinguisher in case a big fire occurs.
