What are the types of Fire extinguisher?

Question

I know there are at least two types fire extinguisher. One handles chemical/gas, the other does _____( like wood and other surfaces, but the name escapes me). I had the question wrong at first, but I fixed the wording. Please fill in the blank; it's for my Physical Science course which is tomorrrow, and since dying is not high on my list of things to do, I could really use the help. Thank you

I only need like, one word, cuz I only get about two inches to answer. It's a one word answer.

Answer 1

See also reference 1, below.

Class A is for "common combustibles," mainly solids like paper, wood, that sort of thing. Pressurized water can extinguishers are for Class A fires, among other types.

A Class B extinguisher works on liquids, such as gasoline, kerosene, and so forth. Many of these use a chemical foam.These do not work well on 3-dimensional fires, i.e.: a fire where something is leaking from a pipe or a tank, and the flaming liquid is moving.

Class C fires are electrical fires. In order to extinguish these types of fires, the extinguishing agent cannot be electrically conductive, such as the foam that is sometimes used in Class B extinguishers. Once de-energized (the power is turned off), they can be treated as Class A fires.

Class D fires are metal and metal powder fires. Compounds such as "Purple K" and similar are used; these are normally chemical salts (including sodium chloride, or table salt, for some extinguishers), along with a compound that helps fuse it together under heat to keep it from cracking. They are poured on top of the burning metal, and melt to form an air-impermeable seal. In reality, if you have burning metals, then leaving the room is the best option. Class D extinguishers are used only under unusual circumstances.

These are the types of extinguishers based on the class of fire they are to be used on. There are different types of extinguishers based on the way in which they work. For example, the pressurized water can squirts water; the carbon dioxide extinguisher is full of carbon dioxide that displaces oxygen (and is very cold) to remove oxygen and some heat from the fire; ABC extinguishers with monoammonium phosphate displace oxygen and melts to form an impermable seal to keep oxygen out; Halon extinguishers mess with the self-sustaining chemical chain reaction, and are very effective- but some types of halons tend to break down ozone, so they are being replaced with newer agents.

Check out the Wikipedia link for plenty of information on the types of extinguishers and the types of fires.

Good luck on your test. I think the word you're working for is "common combustibles," or perhaps "solids."

Answer 2

Ordinary Combustibles
Fires in paper, cloth, wood, rubber, and many plastics require a water type extinguisher labeled A.

CO2

Flammable Liquids
Fires in oils, gasoline, grease and other flammable liquids require an extinguisher labeled B.

Electrical Equipment
Fires in wiring, fuse boxes, computers, and other electrical sources require an extinguisher labeled C.



Dry Chemical
Flammable Liquids
Fires in oils, gasoline, grease and other flammable liquids require an extinguisher labeled B.

Electrical Equipment
Fires in wiring, fuse boxes, computers, and other electrical sources require an extinguisher labeled C.


Multi-Purpose
Ordinary Combustibles, Flammables Liquids, or Electrical Equipment
Multi-purpose dry chemicals fights all fires in class A, B, or C. This type of extinguisher may be the best to have for your home.

Answer 3

Co2 is carbon dioxide,which puts out most fires which do not have their own oxygen supply. and since it is a gas and not liquid it is safe for electrical. I would just be careful for liquid fuel since the force of the gas coming out can spread the liquid. IE a chip pan fire, with hot oil spraying you can be injured or spread the fire if not thinking, as in turning off the heat source. but the best in a car or home, a as long as you remember that also you need oxygen as well as the fire, so tackle and get out fast before you collapse, leave the real fires to the fire brigade. you endanger yours and their life's. If you are still not sure ask your local fire station they will help you understand

Answer 4

There are basically four different types or classes of fire extinguishers, each of which extinguishes specific types of fire. Newer fire extinguishers use a picture/labeling system to designate which types of fires they are to be used on. Older fire extinguishers are labeled with colored geometrical shapes with letter designations. Both of these types of labels are shown below with the description of the different classes of extinguishers.

Additionally, Class A and Class B fire extinguishers have a numerical rating which is based on tests conducted by Underwriter’s Laboratories that are designed to determine the extinguishing potential for each size and type of extinguisher.

Fire Extinguisher Ratings
Class A Extinguishers will put out fires in ordinary combustibles, such as wood and paper. The numerical rating for this class of fire extinguisher refers to the amount of water the fire extinguisher holds and the amount of fire it will extinguish.

--------------------------------------------------------------------------------

Class B Extinguishers should be used on fires involving flammable liquids, such as grease, gasoline, oil, etc. The numerical rating for this class of fire extinguisher states the approximate number of square feet of a flammable liquid fire that a non-expert person can expect to extinguish.

--------------------------------------------------------------------------------

Class C Extinguishers are suitable for use on electrically energized fires. This class of fire extinguishers does not have a numerical rating. The presence of the letter “C” indicates that the extinguishing agent is non-conductive.

--------------------------------------------------------------------------------

Class D Extinguishers are designed for use on flammable metals and are often specific for the type of metal in question. There is no picture designator for Class D extinguishers. These extinguishers generally have no rating nor are they given a multi-purpose rating for use on other types of fires.

Answer 5

water
CO2
powder
foam

they're the main 4 in europe

Answer 6

One word huh? Well based on your question I would go with "solids", but that is really oversimplifying things.

Answer 7

water , foam & co2
