Understanding fire extinguishers and their uses is an important step of learning fire safety. As stated before, different types of fire each require a different fire extinguisher. First, let’s go over the different classes of fires: class A fires, class B fires, class C fires, class D fires, class F fires, and electrical fires. For each class of fire, there is a different extinguisher suitable for use:


Each kind of fire extinguisher puts out a different sort of fire, and there are many types of fires. It’s important to know the types of extinguishers and fires so you can match them correctly and not further ignite a fire. We offer a range of cheap fire extinguishers so we have something for everyone’s budget, but all our cheap fire exintguishers meet all qualtiy standards.
Different extinguishers use different ingredients. Dry chemical extinguishers use a powder-based agent that prevents dangerous reactions from occurring in the fire. This agent includes potassium chloride, sodium bicarbonate, and more.

Foam extinguishers use film-forming foams and fluoro-protein as well as alcohol-resistant foams and a compressed air foam system. These foams smother a fire and prevent oxygen from making the fire worse.

Water extinguishers use water to cool off the material that is burning. They can take form in pump-type water, pressurized water, and mist.

CO2 extinguishers extinguish fires by displacing the oxygen and heat from the zone that’s combusted. The ingredients they use include halocarbon replacements, novec 1230, and E-36 cryotec.
The short answer to this question is that using the wrong fire extinguisher could potentially make the fire even worse. That is why it’s so important to know the classes of fires and types of extinguishers.
Technically, there aren’t any all-purpose extinguishers yet, but you can fairly safely use dry chemical extinguishers on most fires with just a few exceptions.
After finding the correct extinguisher for the fire at hand, it’s vital to make sure that it is working properly. Here are a few things you can do to ensure that your fire extinguisher will do the job right.

Check for the following:

1. easy access- make sure nothing is blocking a person’s ability to reach the extinguisher,
2. the pressure level- check the gauge of the extinguisher to make sure it isn’t too high or too low,
3. working parts- ensure that the hoses, nozzles, and can aren’t damaged or rusted,
4. cleanliness- clean the extinguisher to make sure that there isn’t any oil or grease on the outside, and
5. check the guidelines- some extinguishers need to be shaken, or pressure tested regularly.

When using a fire extinguisher, think of the word PASS. P is for pulling the pen- holding the fire extinguisher with the nozzle pointing away from your body and release the lock.

A is for aiming low- point the extinguisher at the base of the fire. S is for squeezing the lever- do so slowly and evenly. Finally, the last S is for sweeping- sweep the nozzle from side to side.
