Anything that doesn't need an outside source of oxygen to burn, such as ammonium nitrate + fuel oil (fertiliser bomb).
Realistically, i don'tknow of any.
Magnesium metal burns in the presence of CO2 (undergoes what's called
an oxidation-reduction reaction, the Mg is oxidized to MgO and the carbon
is reduced to solid carbon). This can be readily seen by burning Mg in
dry ice. Trying to use a CO2 extinguisher on burning Mg simply causes it
to burn more. This happened to a British ship during its war over the
Falkland Islands. They tried to put out a fire in the hull after it was hit
using CO2 extinguishers and it simply caused it to keep burning. I would
bet there are other metals that will also react with CO2.

∙ 8y agoA CO2 extinguisher is rated as a B-C extinguisher- burning liquids and electrical fires. It is NOT rated to extinguish burning solid materials, such as wood, cloth, paper (Class A). The materials will re-ignite when the gas drifts away. It is also not rated for a class D fire- a combustible metal such as magnesium, zirconium, etc.

What gas is used to put fires?
Carbon dioxide (CO2) is the gas often used to put out fires, especially in fire extinguishers.
What substances do class A extinguishers use to put out fires?
Water, and compressed air as a propellant.
What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
Would fire extinguishers that produce carbon dioxide gas be more effective for fighting ground fires or ceiling fires?
Ground fires. CO2 is heavier than our air and would therefore fall to the ground when released.
Which is true of CO2 extinguishers?
THey must be used on Class B or C fires, they don't leave a corrosive residue which can damage equpiment and is difficult to clean up, and they must be used closer to the fire than other extinguishers.
Will all types of fire extinguisher bottles put out all categories of fires?
Not all fire extinguishers will put out all fires. You must check your fire extinguisher to make sure that is equipped for all fires since different fires must be put out different ways.
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.
What are fire extinguishers best used for?
Fire extinguishers are best used on incipient (at the beginning) fires.
Portable fire extinguishers are labeled for what purpose?
to put out fire In other words, because there are different types of fires there are different types of fire extinguishers. The label will tell you what type of fire it is designed for.
What should you put on a fire?
You should put different things on a fire depending on what is causing the fire. Water is good for fires with nonmetallic combustible sources such as paper or wood. For electrical, grease, or metallic fires you will need fire extinguishers made for those types of fires.
What color are fire extinguishers in India?
normally red, but different fires require different extinguishers which will vary in color.
What type of fire extinguisher should you use for an electrical fire?
It is the Class C fires that invlove electrically energized equipments, and they are suppressed using CO2 extinguishers or dry chemical extinguishers. Certainly the use of water or water-based extinguishers or other water-based suppression equipment is not to be considered.
