Different Fire Extinguisher Types

There are many different fire extinguisher types. This is because depending on the type of fire you want to extinguish, you need to approach it in different ways. For example, we all know that water and electricity are not best friends. Therefore, if the fire involves a live source of electricity, we wouldn't want to spray a water type extinguisher in there. On the other hand, there are specially modified water fire extinguishers which emit a spray mist instead of a jet of water which are suitable for electrical fires. In an ideal world, every person would be trained in the correct use of fire extinguishers. Failing that, everyone should have a basic understanding of how fire extinguishers work, so that ...

Different Fire Types

To help firefighters describe different types of fire more easily, there is a table of fire classes. Each fire is tackled with different fire extinguisher types. Class A Fires are those involving "ordinary combustibles". Class B (USA) and Classes B & C (Europe and Australasia) are those involving flammable liquids and gasses. Class C (USA) and Class E (Australasia) are electrical fires. Electrical fires are not classified i... Read Article ›

How to Extinguish a Class A Type Fire

Class A fires are those involving "ordinary combustibles" (see our tutorial on types of fire for more information). Ordinary combustibles are essentially those which are fuelled by a solid organic material. Plastic, cloth, rubber and wood are examples of such material. Although these types of fire are typically seen in a controlled setting, if they go out of control, then you must work to bring them back under control or extinguish them with the correct extinguisher from the list of fire extinguisher types. In order to sustain itself, every fire needs to satisfy the fire tetrahedron. The normal approach to extinguishing... Read Article ›

How to Extinguish a Class B Type Fire

Class B fires in the USA are those which are fueled by flammable liquids or gases. Europe and Australasia separate these into Class B and Class C fires. The most important point to note with this kind of fire is that among all of the different fire extinguisher types you should NEVER! use a water type fire extinguisher on them since it will more than likely cause the flammable material to spread out over a wider area making the fire worse rather than better. The CO2 is effective because it smothers the fire. So, if you ever want to know what type of fire extinguisher to use on a Class B fire (gasoline, diesel etc) or a Class C fire (natural gas etc), then you can remember the line "fight gas with gas" and reach for that Read Article ›

How CO2 Type Fire Extinguishers Work

Carbon dioxide (CO2) fire extinguishers are one of the fire extinguisher types which contain pressurized carbon dioxide. Under pressure, the gas takes on a liquid form. When the carbon dioxide fire extinguisher is activated however, the pressure difference between the atmosphere outside and the high pressure container causes the liquid to rapidly expand and to take on a gaseous form. All fires need to satisfy the fire tetrahedron to stay burning. The carbon dioxide type fire extinguisher starves the fire of oxygen. This occurs due to the relative difference in density between the carbon dioxide and the oxygen. The oxygen gets pushed away from the burning material, and the burning material is therefore extinguished. Read Article ›

How Water Type Fire Extinguishers Work

Water type fire extinguishers consist of a canister of pressurized water. These are one of the most common fire extinguisher types. When the safety pin is released, and the extinguisher is triggered, a jet of water emerges which can be directed at the base of the fire in order to extinguish it. The main extinguishing component arises from the cooling effect of the water on the burning materials and preventing them from catching fire again. It is important to remember that since water is an electro-conductor, standard water type fire extinguishers should not be used on electrical fires. Some water type fire extinguishers emit a mist rather than a jet. These spray mist extinguishers are suitable for electrical fires, since the mist is not a good conductor of electricity. Also, since the mist can spread more than the jet, t... Read Article ›

Fire Extinguisher Training

There are many sources of information about fire extinguishers and how they work, but it is sometimes difficult to find easy to understand information on how to use fire extinguishers. This article will help you know what to do in the case of a fire. The first thing to remember is : "Don't Panic!". You are no use to anyone if you are not thinking clearly. If you have not received the correct fire extinguisher training, don't worry. There are many companies who are prepared to charge a small fortune to teach you how to use a fire extinguisher, but the simple reality is that fire extinguishers are designed to be easy to use, by anybody---training or no training. On other parts of this wiki, you can read about fire extinguisher types in general, but ... Read Article ›

Electronic Cigarettes : No more Fire Hazards?

Smoking cigarettes is a dangerous habit for many reasons. Obviously, there are some serious health risks. Some would even go so far as to say "guarantees", since lifetime smokers are fairly likely to die from a smoking related illness. Electronic cigarettes are possibly the best solution to this problem, since they remove the nasty health side effects, and replace them with something that is pretty comparable to the real thing. Many electronic cigarette companies advertise these positive health benefits, but so far, I have seen none of them consider the other health and safety benefits. In terms of fire safety, and fire extinguishers in general, one of the major benefits of smoking an electronic cigarette would be that there is no combustible material involved. Electronic cigarettes consist of three major components, regardless of shape, size or brand... Read Article ›
