subject: How Types Of Common Household Fire Extinguishers Work [print this page] Several types of fire extinguishers existSeveral types of fire extinguishers exist. Each one has its strengths in extinguishing a different type of fire. Each one has a distinct purpose in the home, the science lab, or business atmosphere. Home owners must be aware of which type to buy to shield their home from a fire that is on its way to a full blaze.
The first kind of fire extinguisher for review is the water-based version. Water is known as the basic substance that puts out fire- as it takes away the heat and helps extinguish existing flames. Water-based fire extinguishers are best for a shed, barn, or shop in which the fire will be dry and without any grease or oil. Otherwise the fire could spread further.
Dry chemical extinguishers are more convenient for areas at risk to electrical files. The base of the extinguisher fluid is foam or powder that is expelled from the extinguisher by nitrogen. The base is then able to separate the source of an electrical or flammable liquid fire from the air it needs in order to properly maintain combustion.
The next step up in fire extinguishers would be the carbon dioxide fire extinguisher. it is of course named after the fact that the extinguisher will spread the chemical compound carbon dioxide over the fire. The carbon dioxide will remove oxygen from the environment, starving the flame. It also helps extinguish flames by freezing the area it comes into contact with. This can be a double edged sword- make sure you are not in the blast radius to avoid any potential damages from them.
Some of the worst fires around are those in which are flammable metal fires. These types of fires are hard to snuff out, since the metal can't be extinguished through conventional means in a quick time frame. These are known as Class D fires. A special power, sand, or chemical extinguisher will be needed, and for different types of flammable metals you might have to use a different extinguishing method.
A fire extinguisher can go "bad" over the course of time. They may get a leak, and the fire extinguisher will basically fail when it is needed most. Avoid this situation by conducting regular checks on the fire extinguisher. A damaged nozzle is another example of how fire extinguishers can become disabled- likely from a fall or bump. Whatever the case may be. always double check everything on a regular time period so nothing is overlooked when you need it the most.

As they say, it's best to buy a quality product. This is quite true when regarding safety products; you shouldn't trust a life with a faulty product. Buy something that has good reviews from peers, but also don't fret if you are getting a good deal and are not paying top dollar. Find the median for both traits for best effect.
