What is the gas that found in fire extinguishers is?
The gas commonly found in fire extinguishers is carbon dioxide (CO2) for certain types of extinguishers, which is effective for smothering fires by displacing oxygen. Other extinguishers may use chemicals like halon or dry chemical agents such as monoammonium phosphate. Each type is designed for specific classes of fires, such as electrical, flammable liquids, or ordinary combustibles.

For instance, water extinguishers are effective for ordinary combustibles (Class A fires), while foam extinguishers can address flammable liquids (Class B fires). For electrical fires (Class C), carbon dioxide (CO2) extinguishers are suitable, and dry chemical extinguishers can tackle multiple fire classes, including A, B, and C. Additionally, specialized equipment like Class D extinguishers is used for metal fires, and wet chemical extinguishers are ideal for cooking oil fires (Class K).
Which class of fire extinguisher is used for vairious flammable metals?

A, B, C, D and K.
How many fire extinguishers are there?
There is one class of fire extinguisher for each of the 5 classes of fires: A,B,C,D,K. There are different mechanical types of extinguishers, based upon how their internal agent is expelled: contained pressure, external pressure cartridge, and manual pump. There are dozens of different types of agents found inside various fire extinguishers, ranging from ordinary air-pressurized water to many exotic gases and dry chemicals.
Why are fires organized by classes?
There are six classes of fires to define the type of fire, and most importantly, the type of fire extinguisher to use to put out the fire. Here are the fire classes and the types of extinguishers you should use: Class A - Solids (wood, paper, plastic) require water, foam, dry powder, and wet chemical extinguishers. Class B - Flammable liquids (fuel, oil, paraffin) require foam, dry powder, and CO2 gas extinguishers. Class C - Flammable gasses (propane, methane, butane) require dry powder extinguishers. Class D - Burning metals (aluminum, magnesium, titanium) require dry powder (M28/L2) extinguishers. Class E - Electrical items require dry powder or CO2 gas extinguishers. Class F - Cooking oils and fats require wet chemical extinguishers.
